Summary: This study investigated the regulatory mechanisms of EPS biosynthesis in Streptococcus thermophilus CS6 and found that soy peptone and moderate pH conditions contribute to high EPS yield. Factors such as maltose, soy peptone, and initial pH greatly influence the EPS production in CS6. Differential gene expression related to carbohydrate metabolism plays a crucial role in regulating EPS biosynthesis.

Summary: Disinfection treatment increased the abundance of typical bacterial genus with high EPS production ability, leading to significantly enhanced EPS volumetric productivity. EPS produced by DRB showed higher fouling potential on UF and RO membranes, with increased molecular weight and fluorescence intensity. The XDLVO theory revealed that EPS of DRB had significantly higher interaction energy with membranes than control group, indicating caution should be taken when using oxidizing disinfection as pre-treatment for membrane filtration in wastewater reclamation.

Summary: The discovery of the effects of ammonia-generating enzymes like urease and exogenous ammonia on the activity of phosphofructokinase sheds light on the regulatory mechanisms of glycolysis. Urease activity boosts glycolysis and lactic acid fermentation, and ammonia acts as a potent effector of phosphofructokinase. This study shows that urease activity enhances the growth and energy metabolism of Streptococcus thermophilus in milk.

Summary: The study compared the proteomes of virulent, attenuated, and avirulent strains of A. veronii and identified differentially expressed proteins mainly involved in pathways associated with bacterial chemotaxis and microbial metabolism. The expression levels of certain proteins were positively correlated with the virulence of strains, suggesting their potential role as virulence factors. The results of the study may contribute to a better understanding of the pathogenesis of A. veronii.

Summary: This study evaluates the impact of manufacturing conditions on the in vivo functionality of Streptococcus thermophilus BT01 as a probiotic, as well as its ability to modulate urease activity in fecal samples. Results show that the type of cryoprotectant used in the manufacturing process does not significantly affect the viability of S. thermophilus BT01 in fecal samples, but does impact its ability to reduce urease activity. This study highlights the importance of manufacturing conditions in probiotic functionality and provides the first evidence linking S. thermophilus to a specific probiotic mechanism.

Summary: This study investigated the effect of the polarity of the electric field on the organization of probiotic cells within electrosprayed microcapsules. The results showed that by manipulating the polarity and using auxiliary ring-shaped electrodes, the location of the cells within the microcapsules could be controlled, leading to improved viability and higher glass transition temperature.

Summary: The study aimed to characterize the dextran of Leuconostoc mesenteroides SF3, isolated from aguamiel of Agave salmiana, and optimized fermentation conditions to achieve maximum yield of dextran. The dextran produced by L. mesenteroides SF3 showed high water absorption capacity, oil absorption capacity, and emulsion activity, indicating its potential applications in the food industry. The optimized conditions for production could be utilized for commercial production of this high-quality polysaccharide.

Summary: This study isolated Klebsiella pneumoniae from the marine environment, which is influenced by Extracellular Polymeric Substances (EPS) and capable of degrading Poly Cyclic Aromatic Hydrocarbons (PAHs). By optimizing conditions such as specific carbon and nitrogen sources, the study achieved maximum EPS growth and biodegradation of PAHs.

Summary: This study revealed the membrane fouling mechanisms during AnMBR operation for swine wastewater treatment. Results showed that high pollutant removal and energy recovery could be achieved at certain organic loading rates, but higher rates would aggravate the membrane fouling. Microbial analysis based on high-throughput sequencing confirmed the presence of fouling-causing bacteria and their enrichment in the cake layer at higher loading rates.

Summary: Ribosomal phosphoprotein P1 (RPP1) is an integral component of the P-protein stalk in the 60S subunit of eukaryotic ribosomes and is required for efficient translation elongation. Knockout mutation of Arabidopsis RPP1A promotes seedling growth and alters the abundance of proteins involved in various cellular processes, including energy metabolism, nitrogen compound transport, and protein processing.

Summary: Fecal microbiota transplantation (FMT) is effective for treating rCDI in both adults and children. It is still uncertain whether adult fecal donors can provide age-appropriate restoration in pediatric patients due to the critical role of microbiome development in children. This study found that concordant donor strain engraftment and metabolite restoration are associated with FMT outcomes in both adult and pediatric rCDI patients. Additionally, high-resolution variant-calling linked probiotic-strain engraftment with improved gastrointestinal symptoms in adults with irritable bowel syndrome and children with autism spectrum disorder. These findings highlight the importance of strain-level identification when assessing the efficacy of probiotics and microbiota-based therapeutics.
