Annotation:

Crude xylanase preparations from Penicillium corylophilum, Aspergillus niger and Trichoderma longibrachiatum were used to treat Eucalyptus kraft pulp, prior to chlorine dioxide and alkaline bleaching sequences. The enzyme pretreatment improved brightness and delignification of non-delignified and oxygen-bleached samples of eucalyptus kraft pulp. Xylanase preparations from T. longibrachiatum and P. corylophilum were more effective to reduce pulp kappa number. A small reduction in viscosity was obtained when the oxygen-bleached pulp was treated with xylanase preparation from A. niger. For all enzyme samples, the best release of chromophoric material from the pulp was at 237 nm. The enzyme preparation from P. corylophilum was responsible for the highest release of reducing sugar at a dosage interval of 10-20 IU/g dry weight pulp. Scanning electron microscopy studies of oxygen-bleached pulp after xylanase treatment revealed morphological changes, including holes, cracks, filament forming and peeling.

Annotation:

The combined effect of undissociated lactic acid (0 to 180 mmol/liter), acetic acid (0 to 60 mmol/liter), and propionic acid (0 to 12 mmol/liter) on growth of the molds Aspergillus niger, Penicillium corylophilum, and Eurotium repens was quantified at pH 3.8 and 25°C on malt extract agar acid medium. The impact of these acids on lag time for growth (λ) was quantified through a gamma model based on the MIC. The impact of these acids on radial growth rate (μ) was analyzed statistically through polynomial regression. Concerning λ, propionic acid exhibited a stronger inhibitory effect (MIC of 8 to 20 mmol/liter depending on the mold species) than did acetic acid (MIC of 23 to 72 mmol/liter). The lactic acid effect was null on E. repens and inhibitory on A. niger and P. corylophilum. These results were validated using independent sets of data for the three acids at pH 3.8 but for only acetic and propionic acids at pH 4.5. Concerning μ, the effect of acetic and propionic acids was slightly inhibitory for A. niger and P. corylophilum but was not significant for E. repens. In contrast, lactic acid promoted radial growth of all three molds. The gamma terms developed here for these acids will be incorporated in a predictive model for temperature, water activity, and acid. More generally, results for μ and λ will be used to identify and evaluate solutions for controlling bakery product spoilage.

Annotation:

14 strains of Penicillium species were isolated from different localities and habitats from Jeddah, Saudi Arabia and cultivated on two different media: Czapek Dox’s medium, in which NaNO3 is the source of inorganic nitrogen, and Waksman’s medium, in which pepton is the source of organic nitrogen. Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS-PAGE) technique was used in this study to distinguish these isolates. The Penicillium isolates examined in this study consisted of six Penicillium species: Penicillium corylophilum (three isolates), P. rubrum (one isolate), P. citrinum (two isolates), P. crustosum (one isolate), P. canesens (six isolates) and Penicillium sp. (one isolate). The electrophoretic protein patterns from Penicillium isolates grown on Czapek Dox's medium revealed the presence of 17 different bands (out of 14 polymorphic bands, there were three monomorphic bands and two unique bands). The electrophoretic protein pattern of the same isolates grown on Waksman's medium revealed the presence of 12 different bands (out of eight polymorphic bands, there were four monomorphic bands and one unique band). Data were analysed by a clustering method and similarity coefficients using NTSYSpc version 2.02i. Two different phenograms were produced for the studied Penicillium species based on the analysis of the protein banding patterns. Data from the protein banding patterns produced from both media were combined and analysed to produce third phenogram, and the relationships between the species and isolates are discussed.

ABSTRACT Sourdough lactic acid bacteria were selected for antifungal activity by a conidial germination assay. The 10-fold-concentrated culture filtrate of Lactobacillus plantarum 21B grown in wheat flour hydrolysate almost completely inhibited Eurotium repens IBT18000, Eurotium rubrum FTDC3228,Penicillium corylophilum IBT6978, Penicillium roqueforti IBT18687, Penicillium expansum IDM/FS2,Endomyces fibuliger IBT605 and IDM3812, Aspergillus niger FTDC3227 and IDM1, Aspergillus flavus FTDC3226,Monilia sitophila IDM/FS5, and Fusarium graminearum IDM623. The nonconcentrated culture filtrate ofL. plantarum 21B grown in whole wheat flour hydrolysate had similar inhibitory activity. The activity was fungicidal. Calcium propionate at 3 mg ml−1 was not effective under the same assay conditions, while sodium benzoate caused inhibition similar toL. plantarum 21B. After extraction with ethyl acetate, preparative silica gel thin-layer chromatography, and chromatographic and spectroscopic analyses, novel antifungal compounds such as phenyllactic and 4-hydroxy-phenyllactic acids were identified in the culture filtrate of L. plantarum 21B. Phenyllactic acid was contained at the highest concentration in the bacterial culture filtrate and had the highest activity. It inhibited all the fungi tested at a concentration of 50 mg ml−1 except forP. roqueforti IBT18687 and P. corylophilumIBT6978 (inhibitory concentration, 166 mg ml−1). L. plantarum 20B, which showed high antimold activity, was also selected. Preliminary studies showed that phenyllactic and 4-hydroxy-phenyllactic acids were also contained in the bacterial culture filtrate of strain 20B. Growth of A. niger FTDC3227 occurred after 2 days in breads started with Saccharomyces cerevisiae 141 alone or with S. cerevisiae andLactobacillus brevis 1D, an unselected but acidifying lactic acid bacterium, while the onset of fungal growth was delayed for 7 days in bread started with S. cerevisiae and selectedL. plantarum 21B.

Aspergillus fumigatus, A. terreus, Emericella nidulans, E, quadrilineata, Penicillium aculeatum, P. brevicompactum, P. chrysogenum, P. citreonigrum, P. corylophilum, P. fuscum, P. griseofulvum, P. janthinellum, P. nigricans, P. purpurogenum, P. restrictum, P. turbatum, P. verruculosum, Eupenicillium sp. and E. euglaucum were isolated from roots of wheat and ryegrass at seedling, tillering, stem extension, milky ripe and ripe for cutting stages. Frequency of occurrence of species of Aspergillus and Penicillium were higher in roots subjected to washing only and plated onto PDA or PDA amended with lactic acid. In general, species of these two genera were common at the stem extension stage. P. nigricans, P. janthinellum, P. griseofulvum, P. fuscum, Eupenicillium sp. and P. turbatum were isolated at a higher frequency than other species. When introduced at 1% inoculum level A. terreus, P. fuscum, P. griseofulvum and P. nigricans caused severe damage to wheat and ryegrass seedlings especially in sterilised Lancelin soil where they reduced the fresh shoot and root weights of the hosts. When these isolates were screened for antagonism towards Gaeumannomyces graminis var. tritici (Ggt) or agar the strongest antagonism was shown by P. griseofulvum, A. terreus, P. nigricans, P. fuscum and P. janthinellum, whereas other species of the two genera had little or no effect on Ggt. The presence of A. terreus, P. griseofulvum or P. fuscum. with Ggt decreased root rot of wheat and ryegrass caused by Ggt in sterilised and non-sterilised soil, while P. nigricans showed a similar effect in non-sterilised soil only. However, none of the isolates tested would be suitable as biological control agents.

Rhizosphere and rhizoplane of fababean (Vicia faba), melochia (Corchorus olitorius), sesame (Sesamum indicum) and soyabean (Glycine max) plants are inhabited with fungi, mostly Aspergillus flavus, A. niger, Fusarium oxysporum, Penicillium corylophilum, P. cyclopium, P. funiculosum and Rhizopus stolonifer. All fungal species have the ability to produce gibberellin (GA) but F. oxysporum was found to produce both GA and indole-acetic acid (IAA). The optimum period for GA and IAA production by F. oxysporum was 10 days in the mycelium and 15 days in the filtrate at 28°C. The contents of GA and IAA were significantly increased at 0.5 and 1% NaCl after 5 days, but they were lowered at 4% (700 mM) NaCl. Cytochrome P-450 was significantly increased under salt stress at 0.5–7% NaCl. Calcium decreased NaCl stress on F. oxysporum by significant elevating GA biosynthesis at 40 mM Ca<sup>2+</sup>/700 mM Na<sup>+</sup>. GA at 10 µM and Ca<sup>2+</sup> at 10 mM enhanced the germination of seeds under 175 mM Na<sup>+</sup>.

Foods preserved with sorbic acid or its salts can undergo spoilage with the formation of chemicals characterized by odors of plastic, hydrocarbons, or kerosene. 1,3-pentadiene, which is formed through the decarboxylation of sorbic acid or its salts, is one such compound. Numerous species of molds and yeasts have been reported as capable of degrading sorbic acid. This work is aimed to identify the off-odor compounds in samples of strawberry-flavored water preserved with potassium sorbate and sodium benzoate. In addition, the mold isolated from this drink was evaluated for the ability to form undesirable compounds, and the results revealed the presence of 1,4-pentadiene and benzaldehyde in the tested samples. The mold isolated from the samples was identified as Penicillium corylophilum. During its 5-day incubation at 25 °C in a liquid medium, potassium sorbate added at a final concentration of 200 and 400 mg/L was completely assimilated by the growing mycelium and converted into 1,4-pentadiene. The concentration of the latter was determined as 46.5 and 92.6 mg/L, respectively. The decrease in the concentration of sodium benzoate exceeded 53% in the broth spiked at 200 mg/L and 23% at 400 mg/L, resulting in the formation of benzaldehyde.

ABSTRACT Four axenic bacterial species capable of biodegrading nitroglycerin (glycerol trinitrate [GTN]) were isolated from soil samples taken from a washwater soakaway at a disused GTN manufacturing plant. The isolates were identified by 16S rRNA gene sequence homology asPseudomonas putida, an Arthrobacter species, aKlebsiella species, and a Rhodococcus species. Each of the isolates utilized GTN as its sole nitrogen source and removed nitro groups sequentially from GTN to produce glycerol dinitrates and mononitrates (GMN), with the exception of theArthrobacter strain, which achieved removal of only the first nitro group within the time course of the experiment. TheKlebsiella strain exhibited a distinct preference for removal of the central nitro group from GTN, while the other five strains exhibited no such regioselectivity. All strains which removed a second nitro group from glycerol 1,2-dinitrate showed regiospecific removal of the end nitro group, thereby producing glycerol 2-mononitrate. Most significant was the finding that theRhodococcus species was capable of removing the final nitro group from GMN and thus achieved complete biodegradation of GTN. Such complete denitration of GTN has previously been shown only in mixed bacterial populations and in cultures of Penicillium corylophilum Dierckx supplemented with an additional carbon and nitrogen source. Hence, to the best of our knowledge, this is the first report of a microorganism that can achieve complete denitration of GTN.

A sponge cake analog was used to study the influence of pH, water activity (aw), and carbon dioxide (CO2) levels on the growth of seven fungal species commonly causing bakery product spoilage (Eurotium amstelodami, Eurotium herbariorum, Eurotium repens, Eurotium rubrum, Aspergillus niger, Aspergillus flavus, and Penicillium corylophilum). A full factorial design was used. Water activity, CO2, and their interaction were the main factors significantly affecting fungal growth. Water activity at levels of 0.80 to 0.90 had a significant influence on fungal growth and determined the concentration of CO2 needed to prevent cake analog spoilage. At an aw level of 0.85, lag phases increased twofold when the level of CO2 in the headspace increased from 0 to 70%. In general, no fungal growth was observed for up to 28 days of incubation at 25°C when samples were packaged with 100% CO2, regardless of the aw level. Partial least squares projection to latent structures regression was used to build a polynomial model to predict sponge cake shelf life on the basis of the lag phases of all seven species tested. The model developed explained quite well (R2 = 79%) the growth of almost all species, which responded similarly to changes in tested factors. The results of this study emphasize the importance of combining several hurdles, such as modified atmosphere packaging, aw, and pH, that have synergistic or additive effects on the inhibition of mold growth.

Molds were isolated from various foods from Burundi and identified. The ability of these molds to produce aflatoxins, cyclopiazonic acid (CPA), and fumonisins, and the presence of these toxins in the foods were determined. Fusarium moniliforme was the predominant mold isolated from corn. It was also one of the dominant molds isolated from sorghum and sorghum meal. Very few molds were isolated from polished rice, millet, and millet meal. F. semitectum and F. equiseti were the most common molds isolated from haricot and mung beans. F. semitectum was also the predominant mold in peanuts. Peas (Pisum sativum) were predominantly contaminated with Aspergillus ochraceus and A. wentii. The predominant molds isolated from dried nonsalted Ndagala fish (Limnothrissa miodon and Stolothrissa tanganicae) were A. flavus, A. niger and A. sydowi. Dried crushed cassava (Manihot esculenta) tubers and cassava flour were predominantly contaminated with Penicillium citrinum, P. corylophilum, and P. chrysogenum. Very few molds were isolated from the infant food Musalac™. Thirty-seven of 95 isolates of A. flavus and all 5 isolates of A. parasiticus produced aflatoxins. Sixty-seven of the 95 isolates of A. flavus produced CPA, and all aflatoxin-producing A. flavus produced CPA. Ten of 20 isolates of A. oryzae and A. tamarii produced CPA. Fifty-one of 56 isolates of F. moniliforme and all 4 isolates of F. proliferatum produced fumonisins. High levels of fumonisin B1 (12.2 to 75.2 μg/g) were detected in all 6 samples of corn and 1 sample of sorghum meal. Neither aflatoxins nor CPA were found in any of the foods.

Abstract Marine fungi are potentially important resources for bioactive lead compounds for discovering new drugs for diseases such as Alzheimer’s disease. In this paper, the combined bioassay model of acetylcholinesterase (AChE) inhibition, 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging, and Artemia larval lethality was used to evaluate the activity and toxicity of 35 marine fungal strains from seas around China. Their bioactive constituents were revealed by thin layer chromatography (TLC) autography, bioactivity coupled LC–MS/MS and Global Natural Products Social Molecular Networking (GNPS). The results show that the extracts of five strains exhibited higher AChE inhibition ratios than the positive control compound, ‘tacrine’, for which the ratio was 89.8% at 200 μg/ml. Six strains displayed both AChE inhibition (inhibition ratios > 20% at 200 μg/ml) and DPPH scavenging activity (scavenging ratios > 30% at 200 μg/ml) together with low Artemia larval toxicity (lethal rates < 12%). TLC autography showed that the fractioned extracts of four strains contained highly diverse and different bioactive constituents, including strains Talaromyces sp. C21-1, Aspergillus terreus C23-3, Trichoderma harzianum DLEN2008005, and Penicillium corylophilum TBG1-17. From the most potent sample F-11-1-b (derived from Aspergillus terreus C23-3), five AChE inhibitors and seven antioxidants were recognized as bioactive molecules by AChE coupled ultrafiltration followed by LC–MS/MS, and LC–MS/MS coupled with DPPH incubation. Furthermore, with the aid of GNPS, the AChE inhibitors were plausibly annotated as territrem analogues including territrems A–C/D, arisugacin A and an unknown compound 4, and the seven antioxidants were assigned as butyrolactone Ι, aspernolide E, a phenolic derivative and possibly unknown compounds 8–10 and 12.

The physicochemical and bacteriological quality of borehole, bottle and sachet water sold in Anchor University and within Ayobo community Lagos state, Nigeria was investigated Microbiological analysis was carried out using standard microbial procedure to ensure that the water is microbiologically safe. It was screened for the presence of coliforms and other pathogenic microorganisms. The total heterotrophic bacterial count for bottle, sachet and borehole water are 16.50-123.50 x 103CFU/ml, 65.00-73.00 x 103CFU/ml and 0.00-72.00 x 103CFU/ml respectively while the total heterotrophic fungal count for bottle, sachet and borehole water are 5.00-54.50 x 103CFU/ml, 11.00-27.50 x 103CFU/ml and 6.00-16.16.00 x 103CFU/ml respectively. Most probable number was determined using membrane filtration method and it ranged from 15MPN/100ml, 22MPN/100ml, and 27MPN/100 ml for bottle, sachet and borehole water respectively. The mean total coliform per 100ml ranged from 22-30 x 103CFU/ml while fecal coliform ranged from 4-11 x 103CFU/ml. The isolated organisms were Salmonella paratyphi, Shigella flexneri, Proteus vulgaris, Pseudomonas aeroginosa, Escherichia coli, Citrobacter freudii, Salmonella paratyphi, Aspergillus candidus, Aspergillus niger, Aspergillus sulphureus and Penicillium corylophilum. Most of the bacteria isolated showed multidrug resistance to Augmentin, Gentamycin, Pefloxacin, Tarivid, Streptomycin, Septrin, Chloramphenicol and Amoxacillin and showed susceptibility to Ciprofloxacin. The study therefore concludes that these water samples do not meet the WHO standards for potable water; hence they can be potential sources of waterborne diseases.
