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.

An unprecedented global outbreak caused by the monkeypox virus (MPXV) prompted the World Health Organization to declare a public health emergency of international concern on July 23, 2022. Therapeutics and vaccines for MPXV are not widely available, necessitating further studies, particularly in drug repurposing area. To this end, the standardization of in vitro infection systems is essential.

COVID-19 disease, triggered by SARS-CoV-2 virus infection, has led to more than 7.0 million deaths worldwide, with a significant fraction of recovered infected people reporting postviral symptoms. Smart surfaces functionalized with nanoparticles are a powerful tool to inactivate the virus and prevent the further spreading of the disease.

Article Synopsis
  • Cork is primarily used for wine bottle stoppers, but it can contain 2,4,6-trichloroanisole, which causes a musty odor that negatively affects wine quality and leads to financial losses.
  • The presence of yellow stain in cork indicates a degradation linked to higher microbial populations, particularly filamentous fungi that break down lignin, and this microbiota contributes to the formation of chlorophenols and chloroanisoles.
  • Research identified specific fungal and bacterial species associated with yellow stain and demonstrated that certain strains can convert p-hydroxybenzoate into phenol, which can then be chlorinated, potentially leading to the development of 2,4,6-trichlorophenol.
