Although numerous strains belonging to the genus have been described in the last decades for their probiotic and biotechnological potential, others are known to be opportunistic pathogens of humans and animals. Here, we investigated the probiotic potential of two and four type strains belonging to the species Weissella diestrammenae, Weissella uvarum, Periweissella beninensis, Periweissella fabalis, Periweissella fabaria, and Periweissella ghanensis by genomic and phenotypic analyses, and performed a safety assessment of these strains. Based on the results of the survival to simulated gastrointestinal transit, autoaggregation and hydrophobicity characteristics, as well as adhesion to Caco-2 cells, we showed that the , , , , and type strains exhibited a high probiotic potential. The safety assessment, based on the genomic analysis, performed by searching for virulence and antibiotic resistance genes, as well as on the phenotypic evaluation, by testing hemolytic activity and antibiotic susceptibility, allowed us to identify the type strain as a safe potential probiotic microorganism. A comprehensive analysis of safety and functional features of six and type strains was performed. Our data demonstrated the probiotic potential of these species, indicating the type strain as the best candidate based on its potential probiotic features and the safety assessment. The presence of different antimicrobial resistance profiles in the analyzed strains highlighted the need to establish cutoff values to perform a standardized safety evaluation of these species, which, in our opinion, should be mandatory on a strain-specific basis.

Anaerobic bacteria cause a wide range of infections, varying from mild to severe, whether localized, implant-associated, or invasive, often leading to high morbidity and mortality. These infections are challenging to manage due to antimicrobial resistance against common antibiotics such as carbapenems and nitroimidazoles. The empirical use of antibiotics has contributed to the emergence of resistant organisms, making the identification and development of new antibiotics increasingly difficult.

Cutibacterium acnes (C. acnes, formerly classified as Propionibacterium acnes) is a Gram-positive bacterium that contributes to the development of acne vulgaris, resulting in inflammation and pustule formation on the skin. In this study, we developed and synthesized a series of antimicrobial peptides (AMPs) that are derived from the skin secretion of Rana chensinensis.

Currently, there is an increasing use of whole-genome sequencing (WGS) studies to investigate the molecular taxonomy, metabolic properties, enzyme capabilities, and bioactive substances of lactic acid bacteria (LAB) species. In this study, the genome of strain Pediococcus pentosaceus BBS1 was sequenced using the Illumina HiSeq. 2500 platform to determine its classification, annotate its main features, and evaluate its safety characteristics.

In this study, we produced instant dark tea (IDT) by liquid-state fermentation of Ziyang selenium-enriched summer-autumn tea leaves utilizing Eurotium cristatum. Then, the novel mechanism of IDT against obesity was investigated. Our results for the first time revealed that IDT could alleviate obesity by regulating the gut microbiota and promoting adipose thermogenesis.

Aim: Recent studies show that human microbiomes play a significant role in the development of endometrial carcinoma, which is a common gynecological cancer affecting women of reproductive age. This review provides an extensive analysis of how the microbiome interacts with endometrial carcinoma while focusing on its impact on disease progression and potential therapeutic advancements.
Methods: Extensive literature research was conducted to examine how microbial dysbiosis affects endometrial cancer development.
