[Composition of the regulators of bacterial autolysis].

This work was aimed at studying the composition of agents regulating bacterial autolysis and isolated from the lysate of Bacillus subtilis 402, B. subtilis R2 and Micrococcus lysodeikticus biomass by extraction with 5% TCA followed by precipitation from the extract with 5 volumes of isopropanol. Fractions activating bacterial autolysis and fractions inhibiting it were found in all of the preparations after separation on Acrylex P-60.
