Fig. 8From: Characterization of Salmonella endolysin XFII produced by recombinant Escherichia coli and its application combined with chitosan in lysing Gram-negative bacteriaLytic activity of XFII and chitosan on E. coli JM109. Enzymatic lytic activity of formulation formed by chitosan and endolysin against E. coli JM109 without EDTA pretreatment (A). The lytic activity of the combined formulation of XFII and chitosan against E.coli JM109 was determined in the presence ions of Ca2+ (B), Mn2+ (C), Mg2+ (D), Na+ (E), and K+ (F).
