Summary: This study focuses on the production of polysaccharides derived from Iranian Kishk by isolating and culturing lactic acid bacteria. The optimal conditions for EPS production were determined using optimization design methods, resulting in the identification of three strains with high EPS yield. The EPSs produced by these native LAB strains have potential industrial applications or can be used as functional food ingredients.

Summary: The exopolysaccharides (EPSs) of lactic acid bacteria (LAB) have various bioactivities and beneficial characteristics, but their low yield limits their applications in functional food, health, and medicine fields. Understanding the biosynthesis mechanism of EPS is important for accelerating its synthesis and reconstruction.

Summary: The research aims to determine the inhibitory activity of ovocystatin, a cysteine protease inhibitor isolated from egg white, on A beta 42 fibril formation in vitro. The results show that ovocystatin possesses A beta 42 anti-aggregation activity and inhibits A beta 42 oligomer toxicity in PC12 cells. This research may contribute to the development of potential substances to prevent or delay beta-amyloid aggregation, a major cause of Alzheimer's disease.

Summary: The Streptococcus genus consists of both commensal and pathogenic species, and their cell surfaces are covered with a complex range of cell wall polysaccharides that facilitate their interactions and environmental adaptation. This review provides a comprehensive overview of the genetic and compositional diversity of streptococcal cell wall polysaccharides, including rhamnose-glucose polysaccharides, exopolysaccharides, and teichoic acids. It also highlights the species-specific combinations of cell wall polysaccharides, particularly the presence of rhamnose-glucose polysaccharides in certain species and the presence of teichoic acids in other species.

Summary: This study investigated the impact of curd homogenization pressure and Lactococcus lactis strains with different EPS types on texture, syneresis, and microstructure of cream cheese. The presence of non-ropy EPS resulted in higher firmness and serum retention, while ropy EPS contributed to higher yield stress and creaminess. The cluster analysis identified specific EPS-pressure combinations that produced cream cheese with high firmness and serum retention, suggesting potential industrial applications.

Summary: This study focused on the antioxidant and burn wound healing efficacy of exopolysaccharides (EPSs) produced by lactic acid bacteria (LAB). The EPS produced by a selected strain of LAB showed strong antioxidant activity and promoted healing in burn wounds. These findings suggest the potential application of EPS as a burn wound healing agent.

Summary: This study aimed to increase the production of exopolysaccharide (EPS) in the probiotic bacteria Lactiplantibacillus plantarum RO30 by optimizing physio-chemical conditions. By using the one factor at a time (OFAT) method and the Response Surface Methodology (RSM), the optimal carbon, organic nitrogen, and inorganic nitrogen sources were determined to be sucrose, beef extract, and ammonium sulfate, respectively. The yield of EPS (named REPS) was increased to 9.11 +/- 0.51 g/L. RSM experiments further revealed the most favorable cultural conditions, resulting in a maximal REPS yield of 10.32 g/L.
