Inhibition of tobacco ringspot virus by the culture fluid of L-lysine-α-oxidase producing strain

A producing strain of an anti-tumor and antiviral enzyme L-lysine-α-oxidase from Trichoderma was cultured using a technological device of G. K. Skryabin Institute of Biochemistry and Physiology of Microorganisms, Russian Academy of Sciences (Pushchino). L-lysine-α-oxidase activity in the obtained metabolite concentrate was 5.4 U/ml. We studied the effects of the concentrate of active L-lysine-α-oxidase producer on the highly infectious Tobacco ringspot virus and revealed anti-viral activity of it when enzyme concentration was at least 1.0 U/ml. © 2016 Springer Science+Business Media New York.
