Chitosan antimicrobial activity mechanism
WebDec 9, 2015 · Chitosan has two mechanisms to explain its antimicrobial activity. The first mechanism proposed that positive charges on chitosan could bind with negative charges at the bacterial cell surface, which alter permeability and leaks solutes outside the cells. WebThe antibacterial activity of the metal-oxide-incorporated CS nanocomposites can be explained by the following mechanism [4,56,57]. The bactericidal properties of CS are related to the positive charge of CS and negative charge of the cell wall of the pathogen, which result in cell wall lysis and cytoplasmic discharge, leading to the mortality ...
