Extracellular polysaccharide-facilitated selenium nanoparticle assembly and metabolic reprogramming support efficient selenite biotransformation by ARTP-mutagenized Lactiplantibacillus plantarum Vse252.

Abstract excerpt

The environmental accumulation of toxic selenite poses a significant threat to public health and ecosystem sustainability. To improve the capability of microorganisms in selenite detoxification and biotransformation, a superior mutant of Lactiplantibacillus plantarum Vse252 was obtained via ARTP mutagenesis integrated with adaptive evolution. The mutant displayed remarkably enhanced selenite tolerance, with a...
