Вплив іонів свинцю на біосинтетичну спроможність штаму streptomyces recifensis var. Lyticus 2p-15
Impact of lead ions on biosynthetic capacity of Streptomyces recifensis var. lyticus 2p-15 strain

Summary/Abstract: The influence of different concentrations of Pb ions on biosynthetical ability of Streptomyces recifensis var. lyticus 2P-15, which is the producer of compound complex of extracellular enzymes and growth stimulators, was studied. It has been showed, that Pb ions introduced in agar medium have had a stimulative effect on production of surface and depth mycelia. The Pb ions, which have been inoculated into liquid fermentative medium in concentration of 1,0–2,0 mg/l realized directed synthesis of bacterio- and proteolytic enzymes, had an influence on qualitative and quantitative composition of produced enzymes.
