The aim of the present work was to investigate the dynamics of microbial community at DNA and RNA level and the role of bamA and mcrA gene during anaerobic digestion of phenol and p-cresol. Anaerobic digestion was conducted in batch reactors and microbial community dynamics was analysed. Results showed that active microbial community was quite dissimilar in comparison to the total microbial community. Syntrophorhabdus and Bacillus were the dominant active bacterial genera whereas Methanosaeta together with Methanobacterium showed the highest potential activity in the Archaea domain indicating a relevant role of these microorganisms in the anaerobic process. Ecological Networks revealed dissimilar interactions at DNA and RNA level, being the latter a better descriptor of the known roles of dominant OTUs. QRT-PCR results showed that expression of bamA gene correlated positively with instantaneous degradation rate proving for first time its functionality and its relationship with the kinetics of the process.

Hypertension, commonly known as high blood pressure, is a significant health issue that increases the risk of cardiovascular diseases, stroke, and renal failure. This condition broadly encompasses both primary and secondary forms. Despite extensive research, the underlying mechanisms of systemic arterial hypertension-particularly primary hypertension, which has no identifiable cause and is affected by genetic and lifestyle agents-remain complex and not fully understood.

Inflammatory Bowel Disease (IBD) is a persistent ailment that impacts many individuals worldwide. The interaction between the immune system and gut microbiome is thought to influence IBD development. This study aimed to assess some microbiota in IBD patients compared to healthy individuals.

The plastisphere, defined as the ecological niche for microbial colonization of plastic debris, has been recognized as a hotspot of pathogenic and antibiotic-resistant bacteria. However, the interactions between bacteria and phages facilitated by the plastisphere, as well as their impact on microbial risks to public health, remain unclear. Here, we analyzed public metagenomic data from 180 plastisphere and environmental samples, stemming from four different habitats and two plastic types (biodegradable and nonbiodegradable plastics) and obtained 611 nonredundant metagenome-assembled genomes (MAGs) and 4061 nonredundant phage contigs.

It was previously reported that utilization of tetrathionate and 1,2-propanediol by spp. through the metabolic pathways encoded by and operons are related to overgrowth and out-competing microbiota in an anaerobic environment. However, recent knowledge demonstrated which strains in the absence of and genes provoke both higher intestinal colonization and spreading bacteria on faeces in relation to their respective wild-type strain, and generate more prominent inflammation as well.

The gut microbiome, which is composed of bacteria, viruses, and fungi, and is involved in multiple essential physiological processes, changes measurably as a person ages, and can be associated with negative health outcomes. Microbiome transplants have been proposed as a method to improve gut function and reduce or reverse multiple disorders, including age-related diseases. Here, we take advantage of the laboratory model organism, Drosophila melanogaster, to test the effects of transplanting the microbiome of a young fly into middle-aged flies, across multiple genetic backgrounds and both sexes, to test whether age-related lifespan could be increased, and late-life physical health declines mitigated.
