Summary: The increasing salinity levels under reclaimed water irrigation have negative effects on plant growth, but the combination of B. subtilis and S. cerevisiae can promote rice physiological indices, with B. subtilis having a greater effect. Soil nitrogen concentration and the amount of B. subtilis applied are major factors influencing leaf physiological indices.

Summary: This study evaluated the use of two microencapsulated probiotic additives in extruded diets for juvenile Nile tilapia, and found that the addition of probiotics improved the zootechnical and health aspects of the fish. The fish fed with probiotic diets showed greater survival, improvements in feed conversion, as well as in the specific growth rate. Histological and histomorphometric analysis revealed that the probiotic treatments had a positive effect on the intestinal health of the fish. Metagenomic evaluation also showed significant differences in the intestinal microbiomes between the treatments. In the challenge against the pathogen A. hydrophila, the probiotic treatments exhibited lower cumulative mortality compared to the control group.

Summary: The study revealed that the culture fluid of Bacillus subtilis subsp. natto contains nattokinase, which can inhibit the transfer of antibiotic resistance plasmid pCF10 in Enterococcus faecalis populations. This inhibition is attributed to the cleavage of peptide pheromones by the extracellular proteases of B. subtilis subsp. natto, reducing the frequency of conjugative plasmid transfer and providing a potential probiotic-based method for interfering with antibiotic resistance transfer in E. faecalis.

Summary: The study demonstrated that the supplementation of MMDA significantly improved the adverse effects of AFB(1) and OTA in broilers, including increased feed conversion ratio, reduced biochemical alterations, decreased intestinal pH values, and lower E. coli counts in the ceca of birds.

Summary: The study demonstrates that canine-derived Enterococcus faecalis and E. faecium strains adhere better to the duodenal mucosa of healthy beagles compared to chicken-derived strains, with canine E. faecalis showing the highest hydrophobicity levels. This suggests that both bacterial species and host origin may influence mucosal adhesion.

Summary: Human milk oligosaccharides (HMOs) are important components in human milk, and the engineered microbial routes have been researched for large-scale production. The selection of host strains and expression of appropriate glycosyltransferase are key factors in HMOs production using engineered microbial pathways.

Summary: This study demonstrated that purified paraprobiotic Enterococcus faecalis (EC-12) and an E. faecalis-based formulation (Med Lan-S) can protect against irinotecan-induced intestinal mucositis by downregulating the inflammatory response. EC-12 also prevented bacterial translocation to the blood induced by irinotecan.

Summary: The widespread use of biomass for energy and chemical production is hindered by its recalcitrant nature. Consolidated bioprocessing (CBP) can reduce overall cost by combining enzyme production, biomass hydrolysis, and sugar fermentation. Cellulosomes found in anaerobic microorganisms are efficient for biomass depolymerization. However, the conversion rate of synthetic cellulosomes is currently low. Displaying more complex cellulosome structures and tethering them onto living cells hold the potential to enhance overall efficiency.

Summary: This study examined the effects of Bacillus subtilis-fermented products (SFPs) and Bacillus licheniformis-fermented products (LFPs) on broiler growth performance, intestinal morphology, gene expression, cecal microbiota community, and microbial carbohydrate-active enzyme composition. The results showed that LFP treatment resulted in improved body weight and average daily gain compared to the control and SFP treatments. LFPs also increased villus heights in the jejunum and enhanced barrier function and antioxidant gene expression in the jejunum and cecum. The cecal microbiota and carbohydrate-active enzyme composition were also significantly influenced by the treatments. Lactobacillus crispatus abundance was higher in the SFP group, while microbial glycosyltransferase 2 gene expression was higher in the LFP group. Overall, LFPs had a greater positive impact on broiler growth promotion compared to SFPs.

Summary: Probiotics are an effective and safe method to reduce toxins in pistachio paste. By increasing the number of microorganisms and decreasing the toxin level, a higher percentage of toxins can be removed. The study found that the addition of probiotics significantly reduced the level of aflatoxin B1 in pistachio paste to permissible limits.

Summary: The study found that the culture fluid of Bacillus subtilis natto can effectively inhibit Enterococcus faecalis biofilm formation, improve biofilm structure, and reduce exopolysaccharide synthesis. Furthermore, the culture fluid of Bacillus subtilis natto also downregulates specific genes involved in E. faecalis cell envelope synthesis and biofilm formation through transcriptome sequencing.
