L-Lysine-α-Oxidase: Acidovorax citrulli Bacterium Inhibitor.

Studies of the effects of Trichoderma harzianum Rifai F-180 culture fluid concentrate containing L-lysine-α-oxidase antitumor enzyme produced by the fungus and the homogenous enzyme, on ultrahazardous bacterium Acidovorax citrulli demonstrated the antibacterial activity of the concentrate. Trichoderma harzianum Rifai F-180 producing L-lysine-α-oxidase was cultured in a technological device at G. K. Skryabin Institute of Biochemistry and. Physiology of Microorganisms, Russian Academy of Sciences. Activity of L-lysine-α-oxidase in the resulted culture fluid concentrate was 0.54 U/ml, activity of the homogenous enzyme was 50 U/mg.
