Abstract:

This paper evaluates the occurrence of the TAs in 71 food products samples. The analysis comprised the following samples: 18 corn puffs, 12 popcorn, 16 corn and 25 corn grits samples, obtained from the shops in Belgrade and Novi Sad during 2019. and 2020. The overall number of the samples with the atropine and scopolamine detections below the LOQ was 61,97%. The percentage of the detection of the tropane alkaloids above the limit of quantification, which may have a negative effect on the health of humans and animals, was 29,57%. The atropine and scopolamine detections are equal in the number of corn puffs, popcorn and corn samples, while 7 samples of corn grits contained the atropine, and 6 of them contained the scopolamine. The highest mean concentrations of the atropine and scopolamine were detected in corn grits, followed by popcorn, then in the corn, while the lowest were in the corn puffs.

Abstract:

The corn silk fly, Euxesta stigmatias Loew (Diptera: Otitidae), and related otitid species can cause severe crop losses to sweet corn, Zea mays L., grown in tropical and subtropical regions. In Florida, the fall armyworm, Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae), and E. stigmatias are two debilitating insect pests on the sweet corn ear that are considered the most costly and difficult to control. Our purpose was to search for resistance to the corn silk fly in a diverse set of maize germplasm that included sweet, floury, field and popcorn, and to determine if any empirical relationship existed between E. stigmatias damage and S. frugiperda infestation in corn ears. The overall means across two sites, 3 yrs and 16 genotypes was 1.77 for corn silk fly damage, rated on a 0 to 4 prototype scale, and 30.1% for fall armyworm infestation. Clear differences existed between the sweet and popcorn types when compared to the field and floury types. The field and floury corns sustained significantly less damage by the corn silk fly than the sweet and popcorn types (0.91 vs 3.33). Five of these genotypes, CEW-R58, DDSB, GT-RI4, Mp704 and ‘Zapalote Chico 2451’, had both lower corn silk fly damage ratings and lower levels of fall armyworm infestation. Across this broad germplasm base no statistical relationship was identified between corn silk fly damage and fall armyworm infestation, suggesting that each insect species responds independently to different maize genotypes. Husk extension was partly related to reduced S. frugiperda infestation, and tip tightness was partly related to reduced E. stigmatias damage. These results indicate that field corn could possibly serve as source of resistance to the corn silk fly for the improvement of sweet corn.

Abstract:

The purpose of the online resource presented here, POPcorn (Project Portal for corn), is to enhance accessibility of maize genetic and genomic resources for plant biologists. Currently, many online locations are difficult to find, some are best searched independently, and individual project websites often degrade over time—sometimes disappearing entirely. The POPcorn site makes available (1) a centralized, web-accessible resource to search and browse descriptions of ongoing maize genomics projects, (2) a single, stand-alone tool that uses web Services and minimal data warehousing to search for sequence matches in online resources of diverse offsite projects, and (3) a set of tools that enables researchers to migrate their data to the long-term model organism database for maize genetic and genomic information: MaizeGDB. Examples demonstrating POPcorn’s utility are provided herein.

Abstract:

Abstract While the use of by- or co-products can help offset the costs of feeding cattle, these feeds often increase in price with increased adoption. Therefore, discovery and characterization of novel feedstuffs could benefit the producer. Our objective was to evaluate the viability of waste popcorn (Zea mays L.) as a feedstuff in ruminant diets. This objective was addressed through a series of two experiments. In Exp. 1, storage stability of popcorn was evaluated. Popcorn was collected on consecutive weekdays in 2 wk from a local cinema. Samples (n = 10) were subdivided into 9 aliquots and subjected to storage, uncovered, for 0, 1, 2, 3, 7, 35, 70, 105, and 140 d. Following the assigned storage time, samples were dried at 55°C to determine weight loss. Following open storage in a laboratory at approximately 24°C, popcorn gained (P < 0.05) between 2.6% (3 d) and 5.6% (105 d) of the original weight through moisture absorption. When dried, however, samples from any length of storage were within 1% of the original weight (P < 0.05). In Exp. 2, a composite sample of popcorn was used in comparison with cracked and steam-flaked corn (Zea mays L.), popped milo [Sorghum bicolor (L.) Moench ssp. bicolor], and rolled barley (Hordeum vulgare L.). Samples were dried at 55°C, ground to pass through a 2-mm screen, and subjected to a batch-culture in vitro assay for digestibility estimates. In vitro true digestibility of popcorn (77.8%) was less (P < 0.05) than estimates for cracked corn (94.8%), popped milo (93.6%), steam-flaked corn (92.6%), or rolled barley (90.3%). From these results, we may conclude that, while popcorn is not as digestible as other commercial energy sources, it may represent a viable option in the arsenal of feed formulation.

Abstract:

Orville Redenbacher's television commercial claims that his gourmet popping corn “blows the top off the popper.” One interpretation of this claim is that Redenbacher's brand produces the most popped corn per package. Does it? What if cost is taken into consideration? Students are consumers too, and they have a stake in finding out which product is best. One interpretation of best is the brand that produces the most popcorn. In this activity, students will use units of measure as the primary tool to answer questions about which brand of popcorn is the best buy. Testing different varieties of popcorn—measuring, popping, and eating them—will engage students because these activities are not contrived. Testing and analyzing the results in class gives students ownership of the mathematics as advertisers' claims are put to the test.

Abstract:

Corn flour, "canjica" (corn grits), corn flakes and popcorn for human consumption, commercialized in Santa Catarina (n=82), were analyzed in order to detect the presence of fumonisins B1 (FB1) and B2 (FB2). From the samples, 92.68% showed detectable levels of Fumonisins (FBs). Corn flour showed the highest level of contamination (91.5%) with average levels of 3.811 and 5.737 mg/g for the home-processed and industrialized products, respectively. The next most contaminated product was popcorn with a average of 2.872 mg/g and an occurrence in 91.6% of the samples. All samples of corn flakes were contaminated with an average of 1.307 mg/g. The product with the lowest levels of FBs was "canjica" with a average contamination of 0.732 mg/g. These results indicated the need of monitoring corn-based products in this state.

Abstract:

Phenolic acids (PAs) are a dominant group of phenolic compounds in cereals, existing mostly bound to compounds of cell wall. In this study, a total of 25 cereal grain samples, including wheat, winter and spring barley, corn, and popcorn, were evaluated for bound PAs and antioxidant activity in a two-year field trial. The PA contents, determined by HPLC, were significantly affected by cereal type. The mean total PA content was highest in popcorn and corn (3298 and 2213 μg/gdm, respectively), followed by winter and spring barley (991 and 908 μg/gdm, respectively) and wheat (604 μg/gdm). Ferulic acid was the most abundant, accounting from 62% to 83% of total PAs (in popcorn and winter and spring barley, respectively). Across cereals, p-coumaric (35–259 μg/gdm) and p-hidroxybenzoic (45–79 μg/gdm) were also dominant, while in corn and popcorn o-coumaric (71 and 89 μg/gdm, respectively) also occurred in higher content. The mean total phenol content ranged from 853 μg GAE/gdm (wheat) to 1403 μg GAE/gdm (winter barley) with DPPH scavenging activity from 14% to 67%, respectively. A significant influence of crop years on the ferulic acid and total PA content was found, while the variability of other PAs was dependent on the cereal type. The results indicated a high health benefit potential of selected cereals.

Abstract:

Fusarium moniliforme Sheldon occurs worldwide on corn intended for human and animal consumption. A closely related species Fusarium proliferatum also occurs frequently on corn. Yellow dent corn, white dent corn, white and yellow popcorn and sweetcorn may be contaminated. Both organisms are capable of producing a group of toxins known as fumonisins, of which Fumonisin B1 (FB1), Fumonisin B2 (FB2) and Fumonisin B3 (FB3) are most common. Fumonisins have been found in corn and corn-based foods worldwide. Fumonisins may be found in sound whole kernel corn at levels at or below 1.0 μg/g. By contrast animal disease problems begin to occur at fumonisin levels above 5.0 to 10.0 μg/g. Corn-based food products that have the most frequent and highest fumonisin levels, besides whole kernels, are corn meal and corn grits. In the United States, corn meal has been found contaminated with Fumonisin B1 at levels from 0.5 to 2.05 μg/g, and grits from 0.14 to 0.27 μg/g. Corn flakes, corn pops, corn chips and tortilla chips have been found negative for fumonisins. Popcorn, sweetcorn and hominy corn have been found contaminated with sporadic, low levels (0.01 to 0.08 μg/g) of fumonisins. The effects of processing on fumonisins in corn are still largely unknown. Heating may cause a loss of fumonisins in corn, but it may be a loss of detectability rather than degradation.

Amber (15 Dec, 30 Dec and 15 Jan) arranged in main plots and three level of plant population (60000, 80000 and 100,000 plants ha-1) in sub plot. Three level of fertility (100:50:50, 150:65:65 and 200:85:85 kg of N: P2O5: K2O ha-1) apportioned in sub-sub plots at the Research farm, Institute of Agricultural Sciences, BHU, Varanasi (U.P.) during late winter (rabi) seasons of 2009-10 and 2010-11 to study the influenced of planting time, fertility level and plant population on yield attributes, grain yield and economics of winter popcorn (Zea mays everta Sturt.) under late sown condition. The popcorn sown on 15th December recorded highest plant height, leaf-area index, dry matter, popcorn growth rate, yield attributes and yield of pop corn were significantly (P<0.05) affected and recorded highest benefit cost ratio (3.78). While, the maintenance of 80,000 popcorn plants/ha proved optimum for pop corn as it significantly (P<0.05) recorded highest number of kernel cob-1,grain yield (32.61 q/ha) and shelling percentage against density of 60,000 plants, while remained at par in straw yield over 100,000 plants. Application of 200: 85: 85 kg N: P2O5: K2O/ha significantly (P<0.05) increased growth, yield attributes and grain yield over 100: 50: 50 and 150: 65: 65 kg N: P2O5: K2O/ha and fetched the highest B: C ratio (3.14).

Abstract:

The aim of this study was to evaluate the combining ability of popcorn lines and hybrids with favorable traits for baby corn production, using lines extracted from the major genotypes of the Brazilian germplasm. From nine popcorn lines, derived from the genotypes Zélia, CMS 42, CMS 43, UEM M2, Zaeli and IAC 112, 36 single-cross hybrids were obtained without reciprocals. In partial diallel crosses, 25 single-cross hybrids were obtained, derived from crosses of five lines of the Zaeli (group I) with five lines from IAC 112 (group II). We recommend using lines derived from Zaeli and CMS 42 in hybrid breeding programs for higher ear yields. The lines P9.5.1 and P9.5.5 (group I) and P8.3 and P8.5 (group II) can be recommended for recombination within each group and for the formation of two synthetic populations for recurrent selection, in order to increase ear yield.

Abstract:

Seventy-nine grain-based food products were purchased from mid-Michigan retail grocery outlets in 1985 and analyzed for the mycotoxins zearalenone and aflatoxin B1 by enzyme-linked immunosorbent assay. Twenty-two percent of these samples contained detectable zearalenone (limit ⩾2.5 μg/kg). Zearalenone was found in breakfast cereal, snack foods, popcorn, corn meal, and cake-muffin mixes representing 10, 11, 57, 78, and 20% of these samples, respectively. The average level of this toxin among the positive samples was 20 μg/kg with maximum levels of 120 and 130 μg/kg being found in samples of corn meal and popcorn, respectively. Zearalenone was not found in any of the wheat flour or baby foods samples. Detectable aflatoxin B1 (limit ⩾5.0 μg/kg) was not found in any of the 79 samples tested.

Abstract:

Abstract. Two of the most commonly used approved grain moisture air-oven reference methods for corn are the air oven method ASAE S352.2, which requires long heating time (72 h) at 103 ± 1°C for unground samples, and the AACC 44-15.02 air-oven method, which dries a ground sample for 1 h at 130 ± 1°C, but there is specific moisture measurement method for popcorn. The AACC 44-15.02 recommends a two-stage drying method for grain over 13%. But this involves more handling and drying time. The objective of this study was to develop an air-oven procedure for popcorn that requires short heating time (1h or less) based on existing reference method for ground corn (AACC 44-15.02). In the process of procedure development, two laboratory mills (Wiley Mini-Mill and Perten 3303 Mill) were optimized for mesh screen size and mill gap settings. The approved AACC method recommends using a 20-mesh screen fitted to the Wiley Mill, which failed, with wires breaking during the grinding process, possibly due to the hard nature of popcorn and/or clogging. It was replaced with the 10-mesh screen which produced larger particle size distribution with ~73% greater than 840 µm. The Perten Mill 3303 was set to gap No. 3 which produced ~68% particles that were greater than 840 µm. Additionally, this study evaluated the effectiveness of single-stage moisture measurement with the 14.5% and 16% moisture popcorn samples. Using the proposed procedure, four varieties of popcorn were tested at three different moisture contents (13%, 14.5%, and 16%). The method using the Wiley grinder and 60 min. heating time yielded oven moisture values which were statistically (p<0.05) similar to the approved ASAE S352.2 and AACC 44-15.02 (72-h, whole grain method). The moisture content of ground samples obtained from the Perten 3303 Mill had elevated moisture measurements and bias across the moisture levels when dried for 60 min. A reduction in heating time to 50 min. resulted in Perten mill samples yielding statistically (p<0.05) similar moisture measurements with the reference 72-h, whole grain method.

Abstract:

Between 2004 and 2007 we examined foods from Japanese retail shops for contamination with ochratoxin A (OTA) and fumonisins B1,B2, and B3. A total of 1,358 samples of 27 different products were examined for OTA, and 831 samples of 16 different products were examined for fumonisins. The limits of quantification ranged from 0.01 to 0.5 μg/kg for OTA and 2 to 10 μg/kg for the fumonisins. OTA was detected in amounts higher than limits of quantification in wheat flour, pasta, oatmeal, rye, buckwheat flour and dried buckwheat noodles, raisins, wine, beer, coffee beans and coffee products, chocolate, cocoa, and coriander. OTA was found in more than 90% of the samples of instant coffee and cocoa, and the highest concentration of OTA, 12.5 μg/kg, was detected in raisins. The concentration of OTA in oatmeal, rye, raisins, wine, and roasted coffee beans varied remarkably from year to year. Fumonisins were detected in frozen and canned corn, popcorn grain, corn grits, cornflakes, corn soups, corn snacks, beer, soybeans, millet, and asparagus. The highest concentrations of fumonisins B1, B2, and B3 were detected in corn grits (1,670, 597, and 281 μg/kg, respectively). All of the samples of corn grits were contaminated with fumonisins, and more than 80% of the samples of popcorn grain and corn snacks contained fumonisins. OTA and fumonisins were detected in several food products in Japan; however, although Japan has not set regulatory levels for these mycotoxins, their concentrations were relatively low.

Abstract:

AbstractVelvetleaf is an economically important weed in popcorn production fields in Nebraska. Many PRE herbicides in popcorn have limited residual activity or provide partial velvetleaf control. There are a limited number of herbicides applied POST in popcorn compared with field corn, necessitating the evaluation of POST herbicides for control of velvetleaf. The objectives of this study were to (1) evaluate the efficacy and crop safety of labeled POST herbicides for controlling velvetleaf that survived S-metolachlor/atrazine applied PRE and (2) determine the effect of velvetleaf height on POST herbicide efficacy, popcorn injury, and yield. Field experiments were conducted in 2018 and 2019 near Clay Center, Nebraska. The experiments were arranged in a split-plot design with four replications. The main plot treatments were velvetleaf height (≤15 cm and ≤30 cm) and subplot treatments included a no-POST herbicide control, and 11 POST herbicide programs. Fluthiacet-methyl, fluthiacet-methyl/mesotrione, carfentrazone-ethyl, dicamba, and dicamba/diflufenzopyr provided greater than 96% velvetleaf control 28 d after treatment (DAT), reduced velvetleaf density to fewer than 7 plants m−2, achieved 99% to 100% biomass reduction, and had no effect on popcorn yield. Herbicide programs tested in this study provided greater than 98% control of velvetleaf 28 DAT in 2019. Most POST herbicide programs in this study provided greater than 90% control of up to 15 cm and up to 30 cm velvetleaf and no differences between velvetleaf heights in density, biomass reduction, or popcorn yield were observed, except with topramezone and nicosulfuron/mesotrione 28 DAT in 2018. On the basis of contrast analysis, herbicide programs with fluthiacet-methyl or dicamba provided better control than herbicide programs without them at 28 DAT in 2018. It is concluded that POST herbicides are available for control of velvetleaf up to 30-cm tall in popcorn production fields.

Abstract:

Northern corn leaf blight, caused by Exserohilum turcicum (Et), is a disease of widespread occurrence in regions where corn, sweetcorn and popcorn are grown. This disease has great potential to cause damage and has been studied for years, but the association of its causal agent with seeds remains unconfirmed. Thus, the availability of a sensitive method to detect and quantify the inoculum in seeds, even at low incidence, is essential. The aim of this study was to develop a method to detect and quantify the presence of the fungus infecting and infesting corn and popcorn seeds. Artificially and naturally infected seeds were employed to develop the medium. The semi-selective medium was composed of carbendazim (active ingredient) (60 mg/L), captan (30 mg/L), streptomycin sulfate (500 mg/L) and neomycin sulfate (600 mg/L) aggregated to the medium lactose casein hydrolysate agar medium. By using this, Et was detected in naturally infected corn seeds, showing 0.124% incidence, in four out of ten analyzed samples. In addition, 1.04 conidia were detected per infested seed. By means of isolation, pathogenicity test, morphological characterization and comparison with descriptions of the species in the literature, the fungus isolated from the seeds was confirmed to be Et. Both infection and infestation were considered low; thus, for studies of Et detection in corn seeds, the use of semi-selective medium and more than 1,200 seeds/sample is suggested.

Abstract:

2-Acetyltetrahydropyridine is an important flavor component in heated corn products such as popcorn and corn chips. The compound exists as a mixture of two tautomers that have different flavor/aroma characteristics. The tautomers also exhibit different chromatographic behaviors and are distinguishable spectroscopically. Alhough their electron ionization mass spectra are different, structure assignment based on low-resolution mass spectra alone has been subject to error. A combination of high resolution exact mass measurement and vapor phase infrared measurement of the separated tautomers was used to unambiguously assign the tautomer structures.

Abstract:

Plant height (PH) is one of the most important traits in maize breeding programs. In popcorn, inferior plant traits can be improved with the dent/flint corn germplasm. In the current study, a total of 259 F2:3 families, developed from a cross between a dent corn inbred and a popcorn inbred, were evaluated for 4 PH traits. Quantitative trait loci (QTLs) for each trait were detected using composite interval mapping methods. In addition, genetic interrelationships were investigated using multiple-trait joint analysis for PH with ear height (EH), and for PH with top height (TH). In total, 6, 5, 2, and 6 QTLs were identified for PH, EH, TH, and TH/PH in single-trait analysis, respectively. Joint-analysis data suggest a strong and complex genetic relationship between PH and EH, and between PH and EH, with no QTLs controlling any single trait independently. In addition, 4 kinds of QTLs detected were classified as closely linked QTLs, pleiotropic QTLs, QTLs with opposite effects, and additional QTLs. It was, consequently, difficult to improve lodge resistance through selection on any individual PH trait. The current study demonstrates that multiple-trait joint analysis not only identified additional QTLs, but also revealed the genetic relationship among different highly correlated traits at the molecular level.

We conducted a survey of aflatoxin B1, B2, G1, and G2, ochratoxin A, and fumonisin B1, B2, and B3 contamination in various foods on the retail market in Japan in 2004 and 2005. The mycotoxins were analyzed by high-performance liquid chromatography, liquid chromatography–mass spectrometry, or high-performance thin-layer chromatography. Aflatoxins were detected in 10 of 21 peanut butter samples; the highest concentration of aflatoxin B1 was 2.59 μg/kg. Aflatoxin contamination was not found in corn products, corn, peanuts, buckwheat flour, dried buckwheat noodles, rice, or sesame oil. Ochratoxin A was detected in oatmeal, wheat flour, rye, buckwheat flour, green coffee beans, roasted coffee beans, raisins, beer, and wine but not in rice or corn products. Ochratoxin A concentrations in contaminated samples were below 0.8 μg/kg. Fumonisins were detected in popcorn, frozen corn, corn flakes, and corn grits. The highest concentrations of fumonisins B1, B2, and B3 in these samples were 354.0, 94.0, and 64.0 μg/kg, respectively.

Abstract:

Five maize hybrids were used in this research: two yellow and one white dent, sweet hybrid, and yellow popcorn. Five brine recipes with acetic acid were examined, of which two with the addition of potassium sorbate. The brines with preservatives were stable for 16 months without colour changes of the liquid and corn cobs. The pH of brines ranged from 3.39 to 3.89. Canned hybrids ZP 366 and ZP 611k in brine without sugar, and with the addition of potassium sorbate and potassium metabisulfite marked as Number 5, showed the best sensory characteristics. The protein content determined in ZP 366 (9.56 %) and ZP 611k (10.23 %) did not vary significantly compared to whole-grain maize flour, while crude fibre content (7.67 and 6.88 %), and ash content (21.96 and 20.72 %) were significantly higher than in flour (crude fibre: 2.40; 2.64 %, ash:1.35; 1.48 %, respectively). This research will be continued in order to implement preliminary findings and new data on this subject.

Full text

Abstract:

Knowledge of the inheritance of C-glycosyl flavone synthesis in maize ( Zea mays L.) silk tissues has been acquired through detailed genetic studies involving primarily germplasm from the Corn Belt Dent race. To test the robustness of this genetic knowledge, we examined C-glycosyl flavone synthesis in a genetically distinct germplasm pool, popcorn. C-glycosyl flavone profiles and levels and the involvement of three specific genes/quantitative trait loci (p, pr1, and sm1) in C-glycosyl flavone synthesis were examined in popcorn germplasm representing at least two races and various diverse geographic regions. Twenty-four inbred lines and 23 hybrids involving these inbred lines and inbred line R17 were characterized for their flavone profiles and levels in silk tissues. Two F2 mapping populations were constructed to examine the involvement of p, pr1, and sm1 on C-glycosyl flavone synthesis. C-glycosyl flavone levels threefold higher than previously reported in Corn Dent Belt materials and a novel class of compounds were discovered. The gene action of sm1 was different, the functional p allele was not always dominant, and pr1 did not affect maysin synthesis. Based on this rather simplistic “model” quantitative trait, it appears that caution should be exercised when attempting to apply quantitative trait locus knowledge accumulated in one germplasm base to a germplasm base that is known to be distinctly unique.

Abstract:

Abstract A rapid, quantitative, inexpensive, and efficient method was developed to determine aflatoxins in corn, corn meal, popcorn, rice, wheat, cottonseed, and peanuts. Samples are ground and extracted with methanol–water (80 + 20). A portion of the extract is cleaned up by passage through a solid-phase separatory column, 500 μL purified extract is derivatized with a bromine reagent, and fluorescence of the solution is immediately quantified with a calibrated fluorometer containing a broad wavelength pulsed xenon light source. This method can quantify aflatoxin from 5 to 5000 ppb without dilution and was linear when applied to samples of noncontaminated corn spiked at 0 to 5000 μg aflatoxin B1/g. Correlation coefficients of the method with LC for multiple analyses for corn (n = 34), cottonseed (n = 32), and peanuts (n = 11) were 0.999, 0.995, and 0.980, respectively. Individual analyses may be conducted in less than 5 min, and grouping of samples is unnecessary. The sensitivity of the method for corn is 5 ppb and the fluorometer, under the operating conditions, has a limit of detection of 0.6 ng aflatoxin B1.

Abstract:

Abstract A single-laboratory method validation was conducted to establish the effectiveness of an immunoaffinity column cleanup procedure followed by liquid chromatography/mass spectrometry (LC/MS) for the determination of fumonisins B1 and B2 (FB1+ FB2) in corn. The test portion is extracted with acetonitrilemethanolwater (25 + 25 + 50). The extract is filtered, diluted with phosphate-buffered saline solution, and applied to an immunoaffinity column. FB1 + FB2 are removed with methanol and directly determined by reversed-phase LC with MS detection using selected-ion monitoring of 2 characteristic ions in each case. Test portions of blank corn samples were spiked with a mixture of FB1 + FB2 to give total levels of 200 and 500 ng/g, respectively. Recoveries of both FB1 and FB2 from spiked samples averaged 90.4101. Based on results for spiked raw corn (triplicates at 2 levels), the relative standard deviation for repeatability ranged from 2.8 to 7.1. The accuracy of the method was demonstrated by analysis of Food Analysis Performance Assessment Scheme (FAPAS) test material. The method was also applied to a small survey of processed corn products such as corn chips, cornflakes, and popcorn.

Abstract:

Abstract. Both perennial grasses and corn biomass residues are non-edible for humans and have high carbohydrate contents that make them promising raw materials for biofuel production. This study evaluated perennial grasses (miscanthus and switchgrass) and corn-based biomass materials (corn stover, stalk, cob, husk, and bran) for high-yielding hydrogen gas production by aqueous-phase reforming (APR). The biomass materials were dissolved in subcritical water to obtain hydrolysates for use as feed solutions in APR. The dissolution experiments showed that hydrolysis percentages and total organic carbon releases were considerably higher in corn biomass fractions as compared to perennial grasses. The highest (66.7 mL H2) and lowest (27.0 mL H2) hydrogen yields were observed when miscanthus and corn bran biomass hydrolysates, respectively, were used as the feed solution. Hydrogen production yields were found to be in the following descending order: miscanthus > corn cob > corn stover > switchgrass > corn husk = corn stalk >> corn bran. In general, the biomass hydrolysates that had less organic carbon resulted in higher hydrogen production. Hydrolysis and gasification results for corn husks from various types of corn (field corn, sweet corn, seed corn, and popcorn) were different. The findings of this study will be beneficial for selection of the right biomass material for production of a specific value-added product from biomass. This study focused on biofuel hydrogen gas, which has the highest specific energy content of all conventional fuels. Keywords: APR, Corn biomass, Hydrogen, Hydrolysis, Miscanthus, Switchgrass.

Abstract Purification of Hageman factor (HF, factor XII) from human plasma is a tedious procedure and the product is not always in the precursor form. Hojima has described a protein derived from corn kernels that inhibits the enzymatic properties of HF. This inhibitor binds to the precursor form of HF. Rapid purification of HF was achieved by using as the major purification step adsorption of this clotting factor to popcorn inhibitor bound to agarose. The product had a specific activity of 50.0 to 67.1 coagulant units of HF per milligram protein, and the yield was 33% to 40% of the HF content of the starting plasma. The purified protein displayed a single band upon unreduced or reduced sodium dodecyl sulfate polyacrylamide gel electrophoresis and less than 0.1% was in an activated form, as measured in coagulant assays. The technique described is more rapid and reliable than methods described earlier.

Abstract:

The contamination of corn with fumonisin produced byFusariumspecies represents an important risk for humans and animals. The incidence ofFusariumspp. and contamination by fumonisin B1(FB1) were studied in field samples from 70 fields of corn during the 2005 and 2006 preharvest seasons in the province of Samsun, Turkey.Fusariumwas the predominant genus isolated from the field samples, withF. verticillioides,F. proliferatumandF. subglutinansbeing the most commonly isolated species. The occurrence ofFusariumspp. varied each year, from 97.14% to 78.57% in 2005 and 2006, respectively. The widespread occurrence of FB1was also observed across the Samsun province. All corn samples infected withF. verticillioides,F. proliferatumandF. subglutinanstested positive for FB1, but none were infected with FB2. Levels of FB1ranged from 0.28 to 8.48 mg kg-1in 2005 and from 0.11 to 2.77 mg kg-1in 2006. The concentration of FB1was lower than 2 mg kg-1in 63.6% of the samples, 28.8% contained from 2 mg kg-1to 5 mg kg-1, while 7.6% contained more than 5 mg kg-1. Our study shows that corn contamination with bothFusariumand FB1was present throughout the Samsun province, but it was strongly dependent on environmental and seasonal conditions. However, there was noFusariumcontamination in certain native white-type and popcorn-type cultivars in 2005 and 2006.

The Southern corn leaf blight, caused by Bipolaris maydis, is a major foliar disease of corn, presentingconsiderable potential of damage, especially in Zea mays, although studies with this pathosystem are still scarce. In thispaper, the effect of different culture media was evaluated on mycelial sporulation and infectivity of conidial inoculum ofB. maydis on leaves of the susceptible cultivar Beija-Flor, of corn-popcorn. Experiments in laboratory and greenhousewere installed in a randomized blocks design with four replications. The mycelial growth and sporulation of B. maydison different culture media (Potato Dextrose Agar, Bean Agar, Coconut Water Agar, Rice Polished Agar, Corn LeafAgar Lactose Casein Agar) were evaluated in the laboratory. In the greenhouse it was evaluated the number of lesionsper leaf and the incidence of disease in susceptible plants inoculated with a suspension of 104 conidia/ml. The culturemedium Polished Rice Agar promoted the highest mycelial growth, but did not promote sporulation. Sporulation washigher on culture media Potato dextrose Agar and Agar Bean. A greater number of leaves with symptoms of the diseaseand a higher number of lesions per leaf were obtained with the inoculum produced in the culture medium Bean Agar.Keywords: Zea mays L, Mycelial growth, Southern corn leaf bligh, Sporulation, Popcorn.
