“…Lactic acid bacteria with gastric and intestinal juice and intestinal absorption capacity can be used as potential probiotics for further development [9]. Li et al [10] found one strain of Lactobacillus helveticus MB2-1 was isolated from traditional fermented milk. The study showed that the strain had good antioxidant activity in vitro, the research on probiotic lactic acid bacteria of milk curd in Inner Mongolia king series showed that Lactobacillus plantarum M1-2 and Lactobacillus rhamnosus M6-1 have good probiotic properties with potential application value through the simulation of artificial gastric juice, bile salt and hydrophobic test [11].…”

In this study, a lactic acid bacterium was isolated and identified from Yushu in China, and its probiotic properties were determined. After cultured in MRS medium, a bacterium was identified as lactic acid bacteria by staining and microscopic observation. And the lactic acid bacteria was further identified as Lactobacillus plantarum by physiological and biochemical tests. The lactic acid bacterium was also identified as Lactobacillus plantarum by 16sDNA determination, and the lactic acid bacteria was named Lactobacillus plantarum YS2 (LP-YS2). The acid resistant activity of LP-YS2 (68.05%) were higher than that of Lactobacillus bulgaricus (LB, 30.35%). LP-YS2 also showed the higher bile salt resistant activities (19.85%, 15.01% and 8.35%) than those of LB (3.08%, 1.87% and 1.44%) in 0.3%, 0.5% and 1.0% bile salt. The hydrophobicity results also showed that LP-YS2 (72.35%) had the higher hydrophobicity than LB (45.67%). LP-YS2 had the good values in food and bio pharmaceutical development.

“…EPS isolated from Bacillus licheniformis [16], Actinobacillus pleuropneumoniae [17], Kingella kingae [18] and Vibrio species QY101 [19] have been reported for antibiofilm activity either by disturbing the established biofilm, inhibiting the early adhesion and reduction of cellular interaction, however the exact mechanism of action remain unknown. Recent reports indicated that, EPS from beneficial bacteria such as Lactobacillus helviticus MB2 [20] and Streptococcus phocae PI80 [4] are capable of inhibiting biofilm formation in many significant pathogens.…”

“…In recent years, LAB EPSs have received increasing attention because LAB strains are generally regarded as safe and of food-grade status [5,6,7]. Thus far, the main LAB strains that have been found to produce EPS are Lactobacillus rhamnosus [8], Lactobacillus plantarum [9], Lactobacillus helveticus [10], Lactobacillus delbrueckii subsp.

The correlation between exopolysaccharide production of Lactobacillus kimchi SR8 under different culture conditions and the DPPH radical scavenging activity of exopolysaccharide was studied. Lactobacillus kimchi SR8 produced 228.24 ± 2.23 mg/L exopolysaccharides with sucrose as the carbon source, Beef Extract-Peptone (2:1) as the nitrogen source and an initial pH of 6.50, whilst the DPPH radical scavenging activity of exopolysaccharides was only 6.85% ± 0.77% at a concentration of 0.20 mg/mL. However, the strain produced 206.79 ± 2.23 mg/L exopolysaccharides with glucose as the carbon source, Peptone-Tryptone (1:1) as the nitrogen source and an initial pH of 7.00, and the DPPH radical scavenging activity of exopolysaccharides increased to 28.34% ± 0.32% at the same concentration. The results showed no correlation between the exopolysaccharide production of lactic acid bacteria and the DPPH radical scavenging activity of exopolysaccharide. Therefore, the antioxidant activity should be taken into consideration when measures are taken to increase exopolysaccharide production if greater antioxidant activity of exopolysaccharides is preferred.
