Summary: This study investigated whether the addition of prebiotics would enhance the persistence of fermented food-associated bacteria in the gastrointestinal tract. Results showed that prebiotics improved the persistence of some species of FAB, but the level of persistence varied depending on factors such as fecal donor, fermented food, and prebiotic used.

Summary: The infant gut microbiota is influenced by antibiotic exposures and prebiotic oligosaccharides found in breast milk. This study analyzed the stool microbiota of 1023 one-month-old infants and found that breastfeeding and antibiotic exposure both decrease gut microbial diversity, but have different effects on microbiota composition. Other factors such as C-section, homebirth, siblings, and exposure to animals also impact microbiota composition. Understanding these factors can help protect and promote a healthy infant gut microbiota.

Summary: This study investigated the effects of donkey whey protein and donkey whey hydrolysate on aging mice. The results showed that these substances could improve the body's aging condition, increase beneficial gut bacteria, and decrease harmful bacteria. Additionally, they positively influenced weight gain velocity, SOD activity, and thymus index. These findings contribute to a better understanding of the potential use of donkey whey protein and donkey whey hydrolysate in delaying aging.

Summary: The study found that whey protein hydrolysate (WPH) can prevent the development of colitis, protect the colonic mucosal layer, and reduce inflammation in mice. WPH intervention also restored gut microbiome balance and increased the secretion of short-chain fatty acids. High doses of WPH had a positive impact on the microbiome, reducing harmful bacterial strains. This research suggests that WPH has anti-inflammatory properties and shows promise in managing colitis.

Summary: The composition and activity of gut microbiota are significantly influenced by dietary intake of carbohydrates and proteins. High fiber intake and protein quality and digestibility can modulate microbial metabolism and composition. Understanding the impact of dietary patterns on host-microbiome interaction is essential for developing targeted interventions.

Summary: Critically ill patients often experience early disruption of their gut microbiota, leading to intestinal dysbiosis. The gut microbiota plays a crucial role in inter-organ communication through various molecular pathways, but the understanding of its effects in different clinical conditions and critically ill patients is still limited. Utilizing the gut microbiota as adjuvant strategies in the ICU could potentially improve the management of infections, brain injury, heart failure, kidney injury, and liver dysfunction. However, more research is needed to fully understand the molecular pathways and evidence is lacking in critically ill patients.

Summary: Shigella continues to be a major contributor to diarrheal illness and dysentery in children under 5 in low- and middle-income countries. This study explored the impact of Shigella infection on the developing gastrointestinal microbiome in infants and found temporal changes in the microbiota associated with the infection. These findings highlight the need for further research on the microbial communities associated with disease susceptibility and resolution.

Summary: In this study, the efficiency of eight different prebiotics was evaluated through in vitro gastrointestinal digestion and fecal fermentation experiments. The results showed that prebiotic treatment can alter the gut microbial community structure, increase beneficial gut microorganisms, and enhance the production of short-chain fatty acids. Machine-learning models were also developed to predict the amount of short-chain fatty acids based on the gut microbial community structure. This study provides insights into the potential use of machine-learning techniques to discover personalized prebiotics.

Summary: Prebiotics are functional foods that target beneficial gut microbial species to improve host health. Arabinoxylan, a non-digestible fiber commonly found in cereal grains like wheat and rice, has profound effects on gut microorganisms. Despite structural differences, common bacterial targets of prebiotics include Bifidobacterium spp. and Lactobacillus spp., which are beneficial for human health.

Summary: By comparing the effects of different formula additives on infant fecal microbiota, it was found that formula supplemented with prebiotics and 1,3-olein-2-palmitin (OPO) helped maintain the diversity and some composition of the gut microbiota similar to breastfeeding. The supplemented formula group showed closer resemblance to breastfeeding in terms of gut microbiota diversity and certain metabolisms compared to the standard formula group.

Summary: The study found that fecal microbiota of bivalves is more diverse than gut microbiota, with a greater presence of transient microbes. However, bivalves retain a distinct resident microbial community dominated by Mycoplasma after fecal egestion. The use of fecal sampling as a nondestructive substitute for direct sampling of the gut is discouraged, and experiments focusing on resident bivalve gut microbiota should consider employing an egestion period prior to gut sampling.

Summary: This study examined the effect of silver carp by-product hydrolysates on the growth of Bifido-bacterium animalis ssp. lactis BB-12. Papain was found to recover more nitrogen and < 1 kDa components from the by-products compared to neutrase and alcalase. Papain-2 h, hydrolysates obtained by papain for 2 hours, showed greater effectiveness in promoting the growth of BB-12. The content of < 1 kDa components, sulfhydryl-containing amino acids, and peptides composed of all the hydrophobic amino acids in the hydrolysates were positively correlated to the growth of BB-12. BB-12 cultured with papain-2 h substitute exhibited a thinner and shorter morphology after 4 hours of cultivation. This study provides a new nitrogen source for Bifidobacterium animalis ssp. lactis BB-12 and suggests a possible strategy for utilizing by-products to reduce aquacultural waste.

Summary: In this study, three major spoilage bacteria of grass carp were artificially inoculated in amino acid solutions and grass carp flesh to investigate their involvement in amino acid degradation and fish quality deterioration. The results showed that Pseudomonas putida highly degraded free amino acids and produced ammonia in grass carp flesh, while Aeromonas rivi-pollensis produced 3-Methyl-butanol and 2-Methyl-butanol through leucine and isoleucine degradation. Shewa-nella putrefaciens showed potent ornithine-decarboxylation activity and released putrescine. Additionally, when S. putrefaciens cooperated with P. putida, more putrescine was produced through the arginine deiminase pathway. In conclusion, this study provided fundamental information on the spoilage mechanisms of freshwater fish and important guidance for quality control strategies.

Summary: This study investigated the effect of oxidation on the dye-binding behavior of myofibrillar proteins. Selected dyes with different charges were incubated with myofibrils oxidized by the Fenton system. The results showed that oxidation increased the particle size, hydrophobicity, and absolute value of Zeta-potential of myofibrillar proteins, while decreasing the net positive charges. The binding ability of myofibrillar proteins towards certain dyes was affected by the pH environment, suggesting that oxidation-induced change in net charges is the driving force affecting the amount of protein-bound dye.

Summary: This study investigated the effects of milk fat globule membrane (MFGM) intervention on spatial memory and cognitive function in mice. The results showed that mice in the M group had more disordered trajectories in the Morris water maze experiment, and immunohistochemical analysis revealed a higher number of neurons in the hippocampal dentate gyrus (DG) area of the M group compared to the control group. Differentially expressed proteins (DEPs) related to synaptic formation and neurotransmitter receptors were also identified. The findings provide new insights into the potential mechanisms of spatial memory and cognitive enhancement by MFGM.
