“…Therefore, based on our results, JP1502 is hydrophobic to chloroform; JP001 is hydrophobic to ethyl acetate, and JP703 and JP705 are hydrophobic to hexane. The results differ from those of Sakoui et al [ 41 ], where chloroform was the most hydrophobic, followed by hexane and ethyl acetate.…”

“…Our LAB strains showed a good percentage of auto-aggregation ranging from 2.11 to 27.77% during 4 h of incubation. This result is similar to the results of Abushelaibi et al and Angmo et al [ 27 , 40 ], but lower than the auto-aggregation of LAB strains reported by Sakoui et al [ 41 ].…”

“…The first six principal components accounted for 89.6%, and the PC1 and PC2 were the most representatives, accounting for 25.2% and 19.2%, respectively. Significant correlations were found between the strains in quadrants 1 and 2 and the variables [ 41 ]. W. cibaria (OP288150), P. acidilactici (OP288151), P. pentosaceus (OP288154), P. pentosaceus (OP288156) and L. brevis (OP288158) were the probiotic candidates with the most potential.…”

In this study, lactic acid bacteria (LAB) strains were isolated from fermented grains of traditional Chinese Baijiu, and their probiotic properties were characterized. Eleven out of 29 LAB strains showed good tolerance to the gastrointestinal tract and bile salts. The surface characteristics (auto-aggregation, co-aggregation, hydrophobicity), safety (hemolytic and antibiotic sensitivity), antibacterial activity against three foodborne pathogens, and antioxidant and hypoglycemic properties of the 11 LAB strains were investigated. Principal component analysis (PCA) was used to comprehensively evaluate LAB strains and their probiotic properties. It was found that Weissella cibaria (OP288150), Pediococcus acidilactici (OP288151), Pediococcus pentosaceus (OP288154), Pediococcus pentosaceus (OP288156) and Levilactobacillus brevis (OP288158) showed high probiotic properties, with potential for commercial development. The results also demonstrated that fermented grains of Chinese Baijiu can be used as a source of high-quality probiotics.

“…have been used as potential probiotics in various fish species due to their good tolerances to acidic pH of stomach and bile salts, excellent adhesion to intestinal epithelial surface, as well as their immune modulation and antagonistic activity toward enteropathogens 24 – 26 . The study has shown that the E. faecium V6-112 was able to resist the different gastrointestinal conditions and showed a high antioxidant property 27 . There were more studies on E. faecium in animal husbandry and other industries, whereas it is limited in the aquaculture.We previously isolated An Enterococcus faecium strain R8a from the intestine of healthy crucian carp Carassius auratus, which showed potential probiotic properties including 28 .…”

In this study, Penaeus monodon were gave basic feed supplemented with three levels of Enterococcus faecium. Then, the expression of non-specific immunity-related genes, and the activities of total antioxidant capacity (T-AOC), superoxide dismutase (SOD), malondialdehyde (MDA), acid phosphatase (ACP), alkaline phosphatase (AKP), phenol oxidase (PO) were evaluated. Meanwhile, the disease resistance test and intestinal flora determination were conducted. The results showed that the MDA levels of 2% and 5% E. faecium groups were significantly lower than that of the control group (P < 0.05). While the SOD and T-AOC and ACP and AKP of experimental groups were significantly higher (P < 0.05), the PO of experimental groups were significantly lower than that of the control group (P < 0.05). In addition, the expressions of immunity-related genes (tlr22, dorsal, lysozyme, crustin, imd, and relish) in the 2% and 5% E. faecalis groups were significantly greater than those in the control group (P < 0.05). After P. monodon was challenged with Vibrio parahaemolyticus for 7 days, the average cumulative mortality of P. monodon in the 2% and 5% groups were significantly lower than that in the 0% group (P < 0.05). With the increase of feeding time, the number of effective OTUs in each group showed a downward trend. At the 14th d, Proteobacteria, Bacteroidetes and Firmicutes, the dominant flora in the intestinal tract of P. monodon. In summary, supplied with E. faecium could increase the expression of non-specific immunity-related genes, enhance the immune capacity of P. monodon.
