Web10 iun. 2024 · Membrane lysis, or rupture, is a cell death pathway in bacteria frequently caused by cell wall-targeting antibiotics. Although previous studies have clarified the biochemical mechanisms of antibiotic action, a physical understanding of the processes leading to lysis remains lacking. WebMost bacteria synthesize a strong cell wall made of cross-linked peptidoglycan. The cell wall is outside the cytoplasmic membrane similar to a “boiler plate” or suit of armor. The cell …
