Lytic Action of Inducible Bacteriocin Clostocin O

Abstract
Clostocin O had a remarkable lytic action toward the exponentially growing organisms of Clostridium saccharoperbutylacetonicum No. 8. The cellular lysis was inhibited by addition of heavy metal cations such as Cu2+, Ni2+, and Cd2+, or fradiomycin and RNase, which had been reported to be the inhibitors for lytic enzymes such as some of clostridial phage-endolysin and clostocin O-endolysin. The formalin-treated organisms and antibiotic-treated organisms, of which autolysin activity was inhibited, were also lysed by clostocin O. The induced cellular lysis by clostocin O was thought to be due to the lytic enzyme attached to clostocin O.
