[The effect of metal ions on the lipolytic activity of Mycobacterium rubrum and Actinomyces streptomycini].
Hydrolysis of olive oil by intact cells of Mycobacterium rubrum 403 and "acetone" preparations of Actinomyces streptomycini 116 was found to be inhibited by the following ions: Ca2+, Mg2+, Mn2+, Ba2+, Co2+, Cd2+, Cu2+, Zn2+, Fe2+, Fe3+, Ni2+. Olive oil is hydrolyzed by the growing culture of Act. streptomycini 116 only in the presence of bivalent metal ions. The biosynthesis of lipase by Mycobatcerium rubrum 403 and Act. streptomycini 116 is increased twofold by magnesium ions. The biosynthesis of lipase by Act. stroptomycini 116 is stimulated also by calcium ions.
