  • The present study was done to examine whether inoculated and established bacteria in the digestive tract of germ-free (GF) chickens affect growth performance, energy availability, nitrogen utilization and neutral detergent fibre (NDF) digestibility of the host bird fed a high-fibre diet. Gnotobiotic (GB) chicks were made from GF birds by co-inoculating with Ruminococcus albus, and Staphylococcus warneri, only the latter of which was established in the chicken gut. No difference was detected among conventional (CV), GF and GB birds in body weight gain, food intake or food efficiency from 7 to 21 d of age. The amount of nitrogen retained was larger in CV than in GF and GB chicks. DE and ME values of the diet and NDF digestibility were higher in CV birds than in GF and GB counterparts. It was concluded, therefore, that the established bacterium S. warneri did not give any beneficial effects on the host bird as judged by growth performance, energy availability, nitrogen utilization, and NDF digestibility.

  • This study was conducted to determine the effects of freezing and supplementation of molasses (M), lactic acid bacteria (LAB) and LAB+enzyme mixture on chemical and nutritional composition of sunflower silage (SF). Sunflower crops were harvested (at about $29.2%{\pm}1.2%$ dry matter) and half of fresh sunflower was ensiled alone and half was frozen (F) at $-20^{\circ}C$ for 7 days. Silage additives were admixed into frozen SF material. All samples were ensiled in glass jars with six replicates for 90 days. The treatments were as follows: i) positive control (non-frozen and no additives, NF), ii) negative control (frozen, no additives, F), iii) F+5% molasses (FM), iv) F+LAB (1.5 g/tons, Lactobacillus plantarum and Enterococcus faecium, FLAB); v) F+LAB+enzyme (2 g/tons Lactobacillus plantarum and Enterococcus faecium and cellulase and amylase enzymes, FLEN). Freezing silage increased dry matter, crude ash, neutral detergent fiber, and acid detergent lignin. The organic matter, total digestible nutrient, non-fiber carbohydrate, metabolizable energy and in vitro dry matter digestibility were negatively influenced by freezing treatments (p<0.05). In conclusion, freezing sunflower plants prior to ensiling may negatively affect silage quality, while molasses supplementation improved some quality traits of frozen silage. Lactic acid bacteria and LAB+enzyme inoculations did not effectively compensate the negative impacts of freezing on sunflower silage.

  • Enantioselective hydrolysis for the producing chiral epichlorohydrin from its racemic substrate was investigated using epoxide hydrolase activity of Rhodosporidium toruloides SJ-4. The effects of reaction parameters including pH, temperature, initial substrate concentration on initial hydrolysis rate and enantioselectivity were analyzed and optimized. The addition of detergent, Tween 20, enhanced the hydrolysis rate and enantioselectivity. Chiral (R)-epichlorohydrin with high optical purity (>99% ee) and yield of 25% (theoretically 50% maximum yield) was obtained from its racemate of 20 mM.

  • The present study was planned to analyze the nutritional quality, microbial counts and fermentative acids in Italian ryegrass (IRG) 80% and alfalfa 20% (IRG-HV) mediated silage inoculated with lactic acid bacteria (LAB) as a probiotic strain for 3 months. Crude protein (CP), acid detergent fiber (ADF), and neutral detergent fiber (NDF), total digestible nutrient (TDN) and In-vitro dry matter digestibility (IVDMD), lactic acid bacteria (LAB), yeast and fungi counts and fermentation metabolites such as lactic acid, acetic acid and butyric acids were analyzed. The result shows that the nutritional quality and metabolite profiles of silage were significantly improved with LAB. For microbial counts, LAB showed dominant followed by yeast as compared with control silage. The pH of the silage also reduced significantly when silage inoculated with LAB. The result confirmed that silage preparation using different crops with L. plantarum inoculation is most beneficial for the farmers.

  • This study was performed to study the removal efficiency of residual organophosphorus pesticides with process for making Perilla Jangachi. Two organophosphorus pesticides(chlorpyrifos-methyl and fenitrothion) were artificially attached to Perilla leaves. Then Perilla leaves were washed with detergent solution for 1minute and rinsed 2 times each for 1 minutes. After washing with neutral detergent solution, Perilla Jangachi was made with 2 steps of optimal condition. As a pretreatment, when soaked with 2% salt concentration solution for 42hours, the removal rate of residual pesticides was 81.75% of chlorpyrifos-methyl and 76.82% of fenitrothion. When Perilla leaves were steamed for 72 seconds after soaking, it became 88.94% and 82.19%, respectively. Finally, after making optimal Perilla Jangachi with 27% onion contents, removal rate was 89.12% of chlorpyrifos-methyl and 82.76% of fenitrothion. Consequently, it appeared that the process for making Perilla Jangachi effectively removed the residual pesticides of Perilla leaves.

  • Influence of the fluorescent whitening agent(FWA)'s adsorption on the whiteness of cotton and on the color change of the dyed fabrics was investigated by repeating wash cycles. Cotton 100% and cotton60/polyester40 blended fabrics were dyed pink, blue and yellow, and cyanuric chloride diamino stilbene(CC/DAS) and distyryl bisphenyl(DSBP) were used for the FWA with laundry detergents. Fabrics were washed at $20^\circ{C}$ with Terg-o-tometer. The FWA adsorption amount was measured by the absorption intensity for the pyridine-water extracted solution. The FWA adsorption increased on the cotton fabric with the wash cycles. Though adsorption of CC/DAS continuously increased up to the 20th cycle, that of DSBP increased sharply before the 10th cycle and reached an equilibrium. The whiteness of the fabrics dried in the shade was greater than that dried under the sunlight through window glass. The color change of dyed fabrics was increased by the number of wash cycles. Pink changed more greatly than blue, yellow or grey cloth. The color change(\Delta{E)}$ of dyed fabric washed repeatedly up to the 20th cycle with the detergent without FWA was less than 1. It is recommended to wash pale colored fabric with the detergent free of FWA.

  • Detergency and soil redeposition of wool fabric in drycleaning solvents, i.e. petroleum solvent, perchloroethylene (PCE), decamethylcyclopentasiloxane($D_5$), with commercial detergents were studied. The detergency of wool soiled cloth in drycleaning solvents without detergents were the order of PCE > petroleum solvent > $D_5$. When commercial detergents were added to the system, the detergency were greatly improved. When 1.0% water was added to solvents/commercial detergents system, the detergency of petroleum solvent and PCE improved whereas that of $D_5$ decreased. The soil redeposition prevention effects of solvents were the same order of detergency, i.e. PCE > petroleum solvent > $D_5$. When commercial detergents were added to the system, the soil redeposition changed depending on solvents and detergents. The soil redeposition in $D_5$ became higher with a commercial detergent, therefore it is important to develop appropriate detergents for $D_5$. Three silicone surfactants were tested for detergency and soil redeposition in $D_5$ to find candidate surfactants for drycleaning detergent formulations. Silicone surfactant PEG/PPG-19/19 Dimethicone was found to be the best surfactant for $D_5$ drycleaning detergents.

  • A field experiment was carried out to determine the effects of conditioning methods and tedding frequency on the drying rate and quality of Italian ryegrass hay. Italian ryegrass was cut with three types of mower conditioners (un conditioned, impeller, roller) and tedded with rake-tedder once or twice daily during field curing. The field drying rate of Italian ryegrass hay was the highest in roller conditioner. Conditioning treatment shorten the date from 1 to 1.5 compare with unconditioned. Drying rate of Italian ryegrass plant had been affected by tedding frequency within 3 days after it was cut, but it was ineffective after 3 days. There is no effect on acid detergent fiber (ADF) and neutral detergent fiber (NDF) but effect crude protein (CP) and relative feed value (RFV) by conditioning treatment in nutritive value of Italian ryegrass hay.

  • The overall objective of this research was to evaluate the effects of spraying sulfuric acid solution, and adding corn meal or molasses to reed canarygrass silage on digestibility of dry matter (DM) and fibrous components in ruminant. DM content of molasses or corn meal treated silages were higher than control. Whereas, sulfuric acid treated silage showed lower DM content compared with untreated control. Acid detergent fiber content was similar among treatments, but neutral detergent fiber (NDF) and hemicellulose concentration were higher in treated silages than those of control. Organic acids content were also increased in treated silages. In contrast, silage pH were lower in treated silages. Treated silages increased both rate and extent of DM and NDF in situ digestibility compared to control at all incubation times. Especially, 7 % molasses and 0.4 % sulfuric acid treated silages increased DM and NDF digestibility significantly after 12 hours of incubation compared with control. In nitro DM and NDF digestibility showed similar trend to in situ incubation. Also treated silages(mo1asses or sulfuric acid treated) incubated in situ had higher particle-associated carboxymethylcellulase activity throughout the incubation except 72 hours.

  • The objective of the study was to measure the beneficial effects of lactic acid bacteria (LAB) inoculation on the nutritive value of oat silage collected from thirteen regions in the Republic of Korea. The contents of crude protein, acid detergent fiber (ADF), neutral detergent fiber (NDF) and crude ash (CA) were slightly lower in LAB inoculated silage when compared with the control silage, whereas inoculation of LAB resulted in increased total digestible nutrient (TDN). Higher number of LAB, but lower count of yeast and fungi indicated the effectiveness of the LAB inoculation on oat silage fermentation. LAB inoculation resulted in low pH silage, which may prevent undesirable microbial growth. The LAB inoculation promoted lactic acid dominant fermentation with marginal levels of acetic acid and butyric acid in oat silage. These data suggest that the LAB inoculation may preserve oat silage at better quality for ruminant animal production.
