Inactivation of bacteriophages by .EPSILON.-poly-l-lycine produced by streptomyces.

Abstract

Some basic amino acids and their polymers are known to have antiphage activities.1 ~3) Recently, Murata et a/.4'5) reported on the inactivation of various phages by L-lysine monomer. We have obtained a novel type of L-lysine polymer, e-poly-L-lysine (n=25~30, -PL), as a
