Gram positive cell wall weak to penicillin
WebDue to the structural difference in the composition of the cell walls of Gram-positive and Gram-negative AgNPs have significantly less effect on the growth of Gram-positive bacteria. The Gram-negative bacteria have a layer of lipopolysaccharides on the outside, and present below a thin (7 to 8 nanometers) layer of peptidoglycan. WebGram-negative bacteria have a hard, protective outer shell. Their peptidoglycan layer is much thinner than that of gram-positive bacilli. Gram-negative bacteria are harder to kill …
