Summary: The alanine racemase (ALRase) in Lactobacillus sakei ZH-2, which plays a significant role in racemization, was analyzed using molecular biological methods. The study revealed that the ALRase in ZH-2 strain had a high similarity (99.4%) to the ALRase in Lactobacillus sakei 23K strain. The enzyme exhibited the highest activity towards alanine and could convert up to 54.5% of l-alanine into d-alanine.

Summary: A study evaluated the probiotic properties of Lactobacillus sakei L-7 and found it had strong adhesion ability and high viability in the gastrointestinal tract. Feeding L. sakei L-7 to mice increased the richness of gut microbiota, abundance of beneficial bacteria, and levels of beneficial metabolites, while decreasing levels of harmful metabolites and inflammatory cytokines. These findings suggest that L. sakei L-7 may promote gut health and have the potential to be used as a probiotic.

Summary: A pyruvated exopolysaccharide named LPE-1 was isolated and characterized from the fermentation broth of Lactobacillus plantarum AR307. LPE-1 was found to contain Galp and Glcp at a molar ratio of 2:1, with a molecular weight of 605 kDa. The presence of pyruvate group in LPE-1 plays a significant role in improving the viscosity and plasticity of dairy products.

Summary: The study investigated the effects of NaCl addition and fermentation with Lactobacillus sakei or Lactobacillus plantarum on proteolysis and protein oxidation in yak jerky. Increasing NaCl content led to a decline in proteolytic activity, peptide content, and free amino acid concentration. Jerky fermented with lactobacillus showed higher proteolysis profiles than the control, and Lactobacillus sakei fermentation resulted in the highest proteolysis. NaCl addition promoted protein carbonylation, sulfhydryl loss, and tryptophan fluorescence quenching. Fermentation with lactobacillus, especially Lactobacillus sakei, effectively reduced protein oxidation in salted jerky. The changes in protein bands observed in the electrophoretogram were attributed to the combined effects of NaCl curing and microbial fermentation.

Summary: To extend the shelf life of shrimp during refrigeration, researchers examined the effects of cell-free supernatant (CFS) of Lactobacillus curvatus and Lactobacillus sakei incorporated with tragacanth gel (TG) coating on microbial and physicochemical quality indicators. Coating shrimps with a CFS-contained gel extended the microbial shelf life by at least two days and improved sensory scores and chemical indicators compared to the control and other treatments.

Summary: Beta-galactosidase is an enzyme with dual activity that can eliminate lactose in milk and produce prebiotic galactooligosaccharides (GOS). This study characterized a beta-galactosidase from Lactobacillus delbrueckii subsp. bulgaricus 43, which showed amino acid replacements compared to other enzymes of the species. The new enzyme acted as a tetramer and exhibited high expression efficiency when cloned into E. coli BL21(DE3). The enzyme had optimal activity at 55 degrees C and pH 6.5, and its activity was positively influenced by Mg2+, Mn2+, and Ca2+. It produced a large amount of GOS with beta-(1 -> 3) and beta-(1 -> 4) linkages, and showed good stability at 55 degrees C.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.

Summary: The potential of multi-layer nanoemulsions for improving the cellular uptake, antioxidant activity, and in vitro bioaccessibility of alpha-tocopherol was examined. The results showed that the multi-layer nanoemulsions significantly enhanced the cellular uptake and antioxidant activity of alpha-tocopherol compared to free coumarin 6. Furthermore, the use of chitosan and dextran sulfate as wall materials in the multi-layer nanoemulsions led to even higher cellular uptake, in vitro bioaccessibility, and antioxidant activity of alpha-tocopherol.
