Web14 sept. 2024 · Previous attempts to produce cell lysates from E. coli via enzymatic cell wall degradation using 0.1 mg/mL lysozyme – without sonication – did not result in extracts with appreciable cell‐free protein synthesis, [9] presumably because the peptidoglycan layer of Gram‐negative bacteria is not very accessible to the enzyme. WebThe interaction of complement and polymyxin with gram-negative bacteria has been investigated by using three strains of Salmonella typhimurium in an attempt to determine the loci of complement action. It has been shown that the bactericidal activities of complement and polymyxin towards a smooth gram-negative organism are similarly affected by …
