Summary: Obesity leads to inflammation, organ damage, and changes in gut microbiota. Plant sources rich in polyphenols have been shown to prevent or delay metabolic abnormalities during obesity. Vachellia farnesiana (VF) is a potent source of polyphenols with antioxidant and anti-inflammatory activities, which may have anti-obesity effects. In vivo and in vitro experiments were conducted to investigate the effects of VF and its polyphenolic extract (VFPE) on obesity-related health issues.

Summary: The objective of this study was to investigate the effects of feeding active dry yeast (ADY) and yeast culture (YC) on fecal bacterial community in finishing bulls fed high-concentrate diets. The results showed that ADY and YC groups had greater relative abundance of certain bacteria compared to the control group, without affecting the diversity of fecal bacteria. It was concluded that supplementation of ADY and YC can improve the large intestinal function in finishing bulls by increasing the abundance of cellulolytic bacteria and altering the abundance of lactic acid-utilizing bacteria.

Summary: The influence of available soil organic matter on the composition and functioning of microbial community during the transformation of barley straw in the soil was studied. It was found that a decrease in the content of available organic matter caused changes in the composition of the microbial community. The taxonomic composition of the soil bacterial community was influenced by the amount of available organic matter in the soil, the addition of straw, and the incubation period.

Summary: The process of straw decomposition is dynamic and is accompanied by the succession of the microbial decomposing community. The bacterial succession during straw decomposition occurred in three phases: early, middle, and late phases, each characterized by different microbial activity and diversity. The soil microbial community may act as an efficient source of cellulolytic microorganisms, and the colonization of the cellulolytic substrate occurs in several phases, each with its own taxonomic and functional profile.

Summary: Recently, we isolated two closely related strains, LMG 31531T and LMG 31532, from soil and plant roots, respectively. Based on genomic and phenotypic data, these strains differ from previously reported species and are described as a new species, Agrobacterium divergens. Our comparative genomic study also discovered conserved proteins that provide insights into the functional evolution of this genus.

Summary: Combined inoculation of legume plants with commercial rhizobia and wild rhizobia isolated from relict legumes showed different effects on symbiosis depending on the plant species. The increase in nodule number was observed in common vetch, while increased acetylene reduction activity was evident in red clover. The wild isolates possessed additional genes related to symbiosis formation and effectiveness, as well as genes associated with plant hormonal status and symbiogenesis processes. Further research on microbial synergy using commercial and wild rhizobia may aid in developing targeted selection methods to enhance the efficiency of legume-rhizobia systems in agriculture.

Summary: In this study, a strain of Pseudomonas sp. R-72008 was found to utilize Alkannin, shikonin, and their derivatives as the sole carbon source. This bacterial strain was able to modify the composition of A/S, decreasing the amount of A/S monomers and increasing the production of A/S oligomers. This research provides new insights into the interactions between bacteria and plant antimicrobials.

Summary: Technogenic processes and agrodevelopment cause significant changes in soil properties. Next-generation sequencing allows detailed investigation of soil microbial composition and functions. This study explored the taxonomic diversity of natural and anthropogenically disturbed soils in Russia using next-generation sequencing. It was found that microbial communities in disturbed soils differ from natural and agrogenic soils, indicating the sensitivity of microbial communities as indicators of human impact on soil.

Summary: Marine macroalgae (seaweeds) play a vital role in coastal ecosystems as primary producers and foundation species. However, little is known about the diversity and impact of viruses in seaweeds. This study characterized viral communities in healthy and bleached specimens of the commercially important green seaweed Ulva, revealing the presence of diverse and novel viruses. The abundance of certain viruses was significantly higher in the bleached samples, suggesting their possible role in seaweed bleaching.

Summary: A study on the soil microbiome under a burial mound in Western Kazakhstan dating from 2500 years ago reveals a significant divergence in microbial communities between buried and surface soils, attributed to diagenetic processes and mineralization. The buried microbiome shows a higher occurrence of degradation processes, indicating a deep difference between the original and buried microbiomes.
