Abstract:
To test the beneficial effect on the following crop of hydrogen released by Hup− soybean nodules, soybean was inoculated with either a Hup− (JH47) or a Hup+ (JH) strain of Bradyrhizobium japonicum. These isogenic strains differ only in that JH47 has a Tn5 inserted in the gene coding for the small hydrogenase subunit which eliminates hydrogenase activity; thus when present in soybean nodules, hydrogen is released into the rhizosphere. Inoculated alfalfa plants were used as the positive control as no hydrogenase activity has ever been found in alfalfa nodules. Soil adjacent to hydrogen releasing (Hup−strain) legume nodules had a significantly higher hydrogen uptake rate than that around the nodules containing the Hup+ strain. Barley grown following soybean inoculated with the Hup− strain exhibited an increased grain yield under field conditions. Key words: Soil, hydrogen oxidization, rotation benefit

Abstract:
Although hydrogen is the most abundant element in the universe, it is not possible to find it in its purest state in nature. In this study, two-stage experimentation was carried out. The first stage was hydrogen production. The second stage was an electrochemical process to hydrogenate soybean oil in a PEM fuel cell. In the fist stage a Zirfon Perl UTP 500 membrane was used in an alkaline hydrolizer of separated gas to produce hydrogen, achieving 9.6 L/min compared with 5.1 L/min, the maximum obtained using a conventional membrane. The hydrogen obtained was used in the second stage to feed the fuel cell hydrogenating the soybean oil. Hydrogenated soybean oil showed a substantial diminished iodine index from 131 to 54.85, which represents a percentage of 58.13. This happens when applying a voltage of 90 mV for 240 min, constant temperature of 50 °C and one atm. This result was obtained by depositing 1 mg of Pt/cm 2 in the cathode of the fuel cell. This system represents a viable alternative for the use of hydrogen in energy generation.

Abstract:
Biodiesel consists of long-chain fatty acid esters, derived from renewable sources such as vegetable oils, and its utilization is associated to the substitution of the diesel oil in engines. Depending on the raw material, biodiesel can contain more or less unsaturated fatty acids in its composition, which are susceptible to oxidation reactions accelerated by exposition to oxygen and high temperatures, being able to change into polymerized compounds. The objective of this work was to determine the oxidative stability of biodiesel produced by ethanolysis of neutralized, refined, soybean frying oil waste, and partially hydrogenated soybean frying oil waste. The evaluation was conducted by means of the Rancimat® equipment, at temperatures of 100 and 105ºC, with an air flow of 20 L h-1. The fatty acid composition was determined by GC and the iodine value was calculated. It was observed that even though the neutralized, refined and waste frying soybean oils presented close comparable iodine values, biodiesel presented different oxidative stabilities. The biodiesel from neutralized soybean oil presented greater stability, followed by the refined and the frying waste. Due to the natural antioxidants in its composition, the neutralized soybean oil promoted a larger oxidative stability of the produced biodiesel. During the deodorization process, the vegetable oils lose part of these antioxidants, therefore the biodiesel from refined soybean oil presented a reduced stability. The thermal process degrades the antioxidants, thus the biodiesel from frying waste oil resulted in lower stability, the same occuring with the biodiesel from partially hydrogenated waste oil, even though having lower iodine values than the other.

Abstract:
Soybean oil (SBO), menhaden fish oil (FO), chicken fat (CF) or hydrogenated soybean oil (HSBO) were incorporated at 5% of the total diet to study changes in the immunological status of both Japanese quail (JAP) and Bobwhite quail (BOB). The SBO diet, in which 66% of the total fatty acids were polyunsaturated fatty acids (PUFA), was rich in linoleic acid (LA 18:2 n-6), alpha-linolenic acid (ALA 18:3 n-3) and low in saturated fatty acid (SFA). The FO diet which contained about 50% PUFA, had only 40% n-6 fatty acids and 8% n-3 PUFA. The trans fatty acid isomers and other monounsaturated fatty acids (MUFA) were high in the HSBO diet. The diet containing CF provided a relatively balanced fatty acid composition with 18% SFA, 31% MUFA and 50% PUFA. Plasma fatty acid and hepatic fatty acid profiles consistently reflected their respective dietary lipid treatments. There were no differences in the fatty acid profile between blood and liver within respective dietary treatments in the two species. Dietary fatty acids had no effect on antibody titers against sheep red blood cells (SRBC) at 1, 2 and 8 months following the start of dietary lipid treatment in JAP. However, female JAP fed FO had a significantly (p< 0.05) higher antibody production compared to the other dietary lipid treatments at 4 months following the start of fatty acids supplementation. BOB fed either FO or SBO diets had a higher immunoglobulin G production compared to birds fed the CF diet. The total antibody titer was significantly higher in BOB fed SBO compared to CF. Dietary fatty acids had a significant effect on cell-mediated immunity (CMI) as accessed by toe web thickness 24 hours post intradermal injection of phytohemagglutinin-P (PHA) in both JAP and BOB. In general, birds fed a FO diet had a significantly higher CMI response than those fed HSBO. A diet high in n-3 PUFA increased the index of cutaneous basophil hypersensitivity (CBH), while the high trans fatty acid isomers suppressed the CBH response. By observing a CBH response over a 72-hour period in JAP, it was concluded that quail fed CF or SBO had a different peak response time (12 hours post PHA challenge) and amplitude compared with those fed FO or HSBO (24 hours post PHA challenge). Phagocytic ability was not affected by dietary lipid treatments in BOB while the quail fed FO diet had a faster carbon clearance rate. The FO fed JAP had a significantly higher response (p< 0.05) to concanavalin A ensiformis (CONA) compared to HSBO fed birds. There was no difference in B lymphocyte proliferation stimulated by lipopolysacchride (LPS) in female JAP, whereas it was significantly higher in male JAP fed SBO compared to those fed FO and HSBO. Phorbol 12-myristate 13-acetate/ionomycin calcium salt (PMA/ION) was used to nonspecifically stimulate cell proliferation by increasing chromosome mitosis. Dietary FO or HSBO suppressed cell proliferation stimulated by PMA/ION. However, JAP fed SBO or CF had a significantly higher PMA/ION stimulated lymphocyte proliferation compared those fed FO or HSBO. In male BOB, the FO fed birds had the highest response to all mitogens. In contrast, female BOB did not show any dietary effects by lymphocyte proliferation. Consistent with JAP, BOB fed HSBO had depressed lymphocytes proliferation in response to various mitogens stimulation. In general, female birds had a higher plasma total protein (PTP) and lower pack cell volume (PCV) compared to their males counterparts in both BOB and JAP. In summary, in in vivo experiments, feeding a diet high in menhaden fish oil that is rich in n-3 PUFA enhanced the CMI. There was a minimal effect on antibody production caused by feeding n-3 PUFA in JAP since a significant treatment effect was only found at one sampling period, while BOB were more sensitive to dietary lipid manipulation and had a higher antibody production with SBO or FO treatments. Dietary lipids exerted different effects in the two species in in vitro experiments. While both BOB and JAP fed FO had higher lymphocyte proliferation to CON A mitogen compared to those fed HSBO, only male BOB showed a higher proliferation to LPS. Feeding HSBO that contained a higher content of trans fatty acid isomers, MUFA, but lower PUFA content resulted in the lowest lymphocyte proliferation to various mitogens in both BOB and JAP.

In this study, we found that compound K (K) can form active particles by a modified ethanol injection method combined homogenizer technique for the first time. In addition, adding of compound H (H) and compound T (T) were used as additives. Effect of H or T on physicochemical characteristic of K dispersions were investigated by dynamic light scattering (DLS), transmission electron microscope (TEM), small angle X-ray scattering (SAXS), UV/Visible spectrophotometer (UV-Vis), fluorescence spectrophotometer (FL), differential scanning calorimetry (DSC), high performance liquid chromatography (HPLC), Langmuir monolayers and fluorescence microscopy. In vitro transdermal adsorption experiments of mixed K/H and mixed K/T dispersions were investigated.The result showed mixed K/H dispersions could formed nanoparticle. The average particle size of mixed K/H gradually decreased with adding molar fraction of H. Furthermore, the stability days of K dispersions increased with H. At room temperature (dispersions were gel state), the highest molecule mobility in the hydrocarbon chain region of the particle membrane was found for the mixed dispersions with XH from 0.1 to 0.7. This indicated that the presence of H with XH = 0.9 reduced intermolecular fluidity of membranes. DSC analysis results indicated that incorporation of H into K dispersions with XH from 0.1 to 0.3 reduced the main phase transition enthalpy of K. Partial phase separation of mixed dispersions was found at XH ≥ 0.4. Adding H can maintain the activity of K dispersions. In addition, adding H could increase skin deposition amount of K dispersions. DSC and π-A isotherms results showed that K and H were miscible in the bilayer structures and monolayers. From results of excess area (Aex) and compressibility (κ), mixed K/H monolayers expressed positive Aex and large κ at low surface pressure, whose maximum values occurred at XH = 0.3. Furthermore, negative Aex and small κ were found at high surface pressure at XH ≥ 0.3, suggesting an attractive force existed between molecules and was beneficial to the package of molecules. The thermodynamic analysis suggested that the mixed monolayers with XH = 0.9 had the best stability. Fluorescence images results showed that K molecules aggregated into condensed morphology. At constant surface pressure, adding H made K aggregats become smaller and much less, indicating the mixed monolayers were more expanded. In the case of mixed K/T system, adding T could change structures of K nanoparticles. Adding T into K dispersions with XT ≤ 0.5 made average particle size of K dispersions become smaller, but the largest average particle size with XT ≥ 0.5. Mixed K/T = 9/1 dispersions exhibited the highest storage stability. At room temperature, adding T could increase the intermolecular mobility of the hydrocarbon chain region of K membranes. Furthermore, mixed K/T = 9/1 dispersions showed the highest skin deposition amount. The π-A isotherms results of mixed monolayers was found that two collapses with XT = 0.3, 0.5, and 0.7, suggesting the mixed K/T monolayers were immiscible. From results of Aex, excess Gibbs free energy (ΔGex) and Gibbs free energy of mixing for monolayers (ΔGmix) showed that the mixed K/T monolayers were negative deviations, indicating the tightest packing and more stable thermodynamically. Fluorescence images results showed that K aggregats become smaller and disordering molecular packing morphology with increasing the molar fraction of T, and the molecular aggregats were eliminated at XT ≥ 0.9, indicating addition of T made the mixed monolayers were more expanded. Finally, based on the above results, which can be versatility drug delivery carriers future expectations.

Combined effects of dietary hydrogenated soybean oil and DHA on the growth and DHA deposition of the grouper (Epinephelus coioides) Wei-Ching Chang Advisor: Dr. Houng-Yung Chen Department of Oceanography, National Sun Yat-sen University, Kaohsiung 80424 Taiwan Abstract This study investigated the combined effects of dietary hydrogenated soybean oil (HSO) and DHA on the growth performance and DHA deposition of the grouper (Epinephelus coioides), An 8-week grow-out experiment, followed by a 4-wk washing-out experiment, was carried out. The grow-out experiment was of a 3×2 factorial design, in which soybean oil was replaced by HSO at 0, 50, or 100%, and DHA was supplemented at 3.8 (low) or 10.8 (high) g/kg which is lower or higher than the requirement level, respectively. Juvenile groupers with an initial weight of 64.3 g were stocked in flow-through tanks at 20 fish/tank. Each dietary treatment was randomly assigned to four replicate tanks (N=4). The fish were hand fed twice daily to apparent satiation. The results of the grow-out experiment showed that fish growth was significantly higher in the high DHA group than the low DHA group, and there was no difference among the HSO groups. Body DHA deposition was increased with increasing dietary HSO level. In the washing-out experiment, fish growth was increased with increasing dietary HSO level in the grow-out experiment. DHA deposition was increased with the increasing HSO level in the grow-out experiment. The present results show that dietary inclusion of HSO was associated with body DHA deposition and growth in the grower regardless of dietary DHA levels. While DHA deposition was increased with increasing dietary HSO levels for both experiments, HSO level did not affect the growth of the grouper in the grow-out experiment, but promoted fish growth in the washing-out experiment.
