Summary: Growing evidence suggests a close relationship between gut microbiota and chicken growth performance. Through integrated multi-omics analyses, this study reveals differences in gut microbiota composition and host-microbiota interactions between high body weight (HBW) and low body weight chickens. The HBW microbiota contributes to chicken growth by regulating gut function and homeostasis. Additionally, a specific bacterial consortium derived from HBW chickens shows potential as a chicken growth promoter. These findings provide new insights into the potential links between gut microbiota and chicken phenotypes, with implications for improving chicken growth performance.

Summary: The lignin-degrading bacterial consortium LDC efficiently degrades rice straw lignin in mineral salt medium. The microbial community structure and enzyme expression levels vary greatly during different incubation phases, with significant up-regulation of lignin degradation enzymes. This provides valuable microbial resources and data support for the industrialization of rice straw bio-pulping.

Summary: Microbial community succession during the enrichment of crude-oil-degrading bacteria was analyzed using Illumina high-throughput sequencing. Rhodococcus sp. OS62-1, Dietzia sp. OS33, and Pseudomonas sp. P35 were isolated and used to construct a bacterial consortium with high crude-oil-degrading efficiency, providing technical support for bioremediation of crude oil pollution.

Summary: This study investigated the mechanisms of microbial consortium-mediated growth promotion and arsenic amelioration in rice using transcriptome and proteome analysis. The results indicated that the microbial consortium significantly reduced arsenic toxicity, improved growth of root hairs, and affected the expression of various genes and proteins related to nutrient transport, defense, and metabolism in rice plants exposed to arsenic stress.

Summary: The study found that oat antimicrobial peptides can improve the antioxidant capacity of the colon, reduce the production of inflammatory cells, and have a preventive effect on enteritis. Moreover, oat antimicrobial peptides can change the abundance of intestinal microorganisms, increase the abundance of probiotics, and optimize the diversity of intestinal microorganisms. Oat antimicrobial peptides provide a microbial barrier for gut microbes, producing acidic metabolites that inhibit the growth of harmful bacteria and maintain the integrity of the intestinal mucosa.

Summary: Polyphenols, abundant in plants and fungi, have beneficial bioactive properties. High-resolution mass spectrometry (HRMS) is favored for analyzing their complexity. This study evaluated the advantages of HRMS, using untargeted techniques and online resources, for annotating polyphenols and other molecules. Despite the sensitivity loss compared to low-resolution mass spectrometry (LRMS), HRMS is capable of comprehensively investigating human polyphenol exposure, linking it to human health effects and toxicological mixture effects with other xenobiotics.

Summary: This study applied metabolomic analysis to investigate the chemical composition of kombucha during different production phases and with different types of tea. Results showed that the first phase of acidification had the most significant impact on the chemical composition due to the metabolism of acetic acid bacteria and polyphenols. Additionally, the type of tea mainly influenced the overall composition of polyphenols, with black tea polyphenols being more affected by microbial activity compared to green tea polyphenols.

Summary: Phenanthrene biodegradation is often limited by its low water solubility and dissolution rate. In this study, we engineered a strain of Pseudomonas putida to produce rhamnolipid biosurfactants, which promote the biodegradation of phenanthrene by an engineered strain of Escherichia coli. The two-species consortium exhibited a synergistic effect in degrading phenanthrene, resulting in a significant increase in the degradation ratio.
