Description
Qiuyan Yang's team shows that the amino acid L-cysteine kills the seafood germ Vibrio parahaemolyticus by raising reactive oxygen species inside the cell. Drug-tough strains threaten sea farming, creating demand for eco-friendly germ-killers, and L-cysteine blocked growth at a minimum dose of 7.5 mM.
It damaged membranes, cut final breathing enzymes and defence enzymes, and broke sulfur, one-carbon, fat, and DNA-block energy use, with H2 sulfide from cysteine breakdown driving the oxygen-species surge. It also cut swimming movement and blocked other harmful Vibrio species, presenting a cheap, eco safe Vibrio-illness control lead.
