MvaT negatively regulates pyocin S5 expression in .

Regulatory mechanisms that direct the synthesis and release of pyocin S5, a surface-acting bacteriocin produced by , are relatively unknown. This study aims to identify transcription factors that regulate pyocin S5 expression in PAO1. We captured the transcription factor MvaT using the promoter region upstream of gene (S5P).

Sub-lethal pharmaceutical hazard tracking in adult zebrafish using untargeted LC-MS environmental metabolomics.

Antibiotics in the aquatic environment are dispersed through anthropogenic activities at low concentrations. Despite their sub lethal concentration, these biologically active compounds may still have adverse effects to non-target species. This study examined the response of adult zebrafish to 0.
