[Antibacterial spectrum of lisosubtilin G10X].

Data on the antibacterial spectrum of lysosubtilin G10X, a preparation of lytic enzymes from Bacillus subtilis SK-52 are presented. Lysosubtilin was active against grampositive and gramnegative pathogenic bacteria. When it was used as a substrate of live lyophilized microbial cells the highest lysis levels were observed in B.

[Lysosubtilin G10x--a new antimicrobial agent for treatment and prophylaxis. Physico-chemical properties].

Lysosubtilin G10x, a lytic enzyme from Bacillus subtilis SK-52 was studied with respect to its physico-chemical properties such as effect of optimal conditions and stability. The maximum activity of the enzyme was observed in phosphate buffer at a concentration of the buffer mixture equal to 0.004 M, pH 7.
