A tentative composition and some properties of biosurfactants, type I and type II, from Pseudomonas sp. SW1 are described. Biosurfactant type I and II are soluble in water, dichloromethane, chloroform, and a mixture of chloroform and methanol, respectively. The UV absorption spectrum of biosurfactants showed three characteristic peaks in the range of 212, 250 and 365nm, respectively. As a result of IR spectroscopy, GC/MS analysis and biochemical analysis, biosurfactant type I was a polymeric biosurfactant containing carbohydrate, lipid and protein. The carbohydrate was characterized as rhamnose. The lipid part consists of $C_{14}-C_{23}$ fatty acid when analyzed by GC/MS. The biosurfactant type II was a rhamnolipid consisting of carbohydrate and lipid.

Fabrea salina is a hypersaline ciliate having importance as a live food source for juvenile stages of aquatic animals including smaller invertebrates. The analysis of this ciliate for proximate and biochemical composition was carried out. The moisture, protein, fat, carbohydrate and ash content of F. salina from natural sources were 86.66$\pm$0.380, 56.66$\pm$0.494%, 36.66$\pm$0.614%, 1$\pm$0.073% and 4$\pm$0.182%, respectively. Gas chromatographic analysis (percent area below the curve) revealed that the presence of oleic acid was higher over other fatty acids in both natural and cultured F. salina. The absolute content of oleic acid was higher in natural (18.91% area) than in the cultured (10.74% area) F. salina. Linoleic and linolenic acids were also among major fatty acids with the percentage area of 16.29 and 14.58, respectively. The number of fatty acids in cultured Fabrea was less as compared to the natural ones and the oleic acid was followed by palmitic acid, palmitoleic acid, linoleic acid and stearic acid.

Lectin binding assay was conducted on 3 A. tamarense isolates (AT-A, AT-2 and AT-6). Fatty acid composition of all 3 isolates was analyzed, and total carotenoid content and $\beta$-carotene were also determined. AT-A and AT-2 treated with different lectins in this study showed the positive response, whereas potentially toxic AT-6 did not bind DBA lectin, regardless of different growth phase, but conjugated ConA, PNA, RCA, SBA, UEA and WGA. It is possible that DBA is a desirable method for rapid and easy discrimination of highly toxic A. tamarense. AT-A, AT-2 and AT-6 comprised saturated fatty acids (49.0-61.9%), monounsaturated fatty acids (8.0-20.5%) and polyunsaturated fatty acids (23.2-30.5%). In particular, 22:6 (n-3) polyunsaturated fatty acid in AT-6 had a high abundance, compared with AT-A and AT-2. However, carotenoid content and $\beta$-carotene were not contributed to discriminate each isolate. Due to variability in biochemical composition at different isolates, possibly DBA and 22:6 (n-3) polyunsaturate fatty acid provide a good information for discrimination of AT-6.

Nineteen strains of bacteriocin-producing lactic acid bacteria were isolated from 432 Kimchi samples, and identified by the comprehensive biochemical and morphological tests verifying their cellular fatty acid composition. Using partially purified bacteriocins from these isolates, their inhibitory activities against other lactic acid bacteria and some pathogens, and sensitivity to enzyme and heat treatments were tested. The isolates were identified as Lactobacillus plantarum (2 strains), L curvatus (2 starins), L brevis (2 strains), Enterococcus faecium (6 strains), Leuconostoc mesenteroides subsp. mesenteroides (1 strain) and Lactobacillus sp. (6 strains). The bacteriocins produced by E. faecium strains provided the broadest spectrum of inhibition, affecting against other Gram-positive bacteria including lactic acid bacteria and health-threatening bacteria such as Clostridium perfringens and Listeria monocytogenes. The bacteriocins of Lactobacillus sp., L plantarum and L brevis strains were capable of inhibiting many strains of the lactic acid bacteria, whereas those of L curvatus and L mesenteroides subsp. mesenteroides strains were only inhibitory to a few strains. Generally, the inhibitory activities of both E. faecium and Lactobacillus sp. strains were greater than those of other producer strains. The bacteriocins from the isolates were sensitive to several proteolytic enzymes, and those of L curvatus and L mesenteroides subsp. mesenteroides were also sensitive to lipase and $\alpha$-amylase as well as to proteolytic enzymes. The bacteriocins from the strains of Lactobacillus sp. and a strain of L. brevis were resistant to autoclaving.

A screening was performed to isolate exoploysaccharide-producing microorganisms, which synthesized specific exopolysaccharide for the substitutive of commercial polysaccharides, from natural sources. Soil bacterium, one of 378 mucoid isolates, was finally selected as potential producer of polysaccharides which made the culture broth very viscous and thus examined in detail for optimal medium composition. Isolated strain was identified as Xanthomonas sp. EPS- 1 from the results of morphological and biochemical characteristics. The composition of optimal medium for exopolysaccharide production was as follows: 50 g sucrose, 1.5 g peptone, 2 g KH$_{2}$PO$_{4}$, 2 g MgSO$_{4}$, -7H$_{2}$O, 3 g NaCl, 0.05 g CaCO$_{3}$, 0.07 g FeSO$_{4}$-7H$_{2}$O and 0.05 g MnSO$_{4}$-7H$_{2}$O in 1 liter of distilled water. From the experiments of temperature and pH dependence, the optimal conditions for exopolysaccharide biosynthesis seemed to be 30$\circ$C and 8.0, respectively. About 14.9 gram of maximum exopolysaccharide per liter was obtained at the initial pH 8.0, 30$\circ$C and 250 rpm in a flask culture. The exopolysaccharide EPS-1 had such potential as an emulsifying agent and a gelling agent in comparision with commercial exopolysaccharide.

In the present study, a randomized, double-blind, placebo-controlled trial to determine the effect of conjugated linoleic acid (CLA) supplementation (50:50 ratio of cis-9, trans-11 and trans-10, cis-12 isomers) for 8 weeks on body composition and biochemical parameters in healthy overweight/obese (body mass index, BMI${\geq}23\;kg/m^2$) Korean subjects was performed, Thirty participants (3 males and 27 females) were randomized to receive placebo (2.4 g olive oil/day) or 2.4g/day CLA (mixture containing 36.9% of cis-9, trans-11 and 37.9% of trans-10, cis-12). Eight weeks of CLA supplementation significantly decreased body weight by -0.75kg, BMI by $-0.27\;kg/m^2$, and hip circumference by -1.11 cm. The reduction of body weight was ascribed to the reduction of body fat mass (-0.59 kg) and lean body mass (-0.18 kg), although these changes were not significant. No significant differences in serum lipid profiles, liver function enzyme activities, and protein concentration were observed in either the CLA or placebo groups. These results indicate that short tenn supplementation (8 weeks) with CLA (2.4 g/day) may decrease body weight in Korean overweight/obese subjects.

Vitamin C plays an important role for fish survival, growth and disease resistance. However, the optimal vitamin C for rearing red drum Sciaenops ocellatus juveniles in Vietnam is not known. To address this issue, a 70-day feeding trial was conducted to evaluate the optimal dietary vitamin C requirements for red drum juveniles. Seven isonitrogenous (55.35% protein) and isolipidic (9.07% lipid) diets were formulated to include graded vitamin C concentrations of 23.2, 124.5, 235.2, 423.8, 626.7, 824.6, and 1,027.3 mg/kg, respectively. The results showed that fish fed on 423.8 mg/kg vitamin C diet had the highest growth rate, which can be linked to the increased feed utilization. Broken-line analysis indicated that the optimal dietary vitamin C requirements of red drum juveniles were 342.92 and 405.80 mg/kg for growth parameters, feed utilization, body composition and biochemical parameters of serum. Based on these parameters the optimal vitamin C supplementation level for red drum juveniles was estimated in the range of 342.92-405.80 mg/kg vitamin C in the diets with direct applications in producing artificial feed for rearing juveniles of this species in Vietnam.
