[Biosynthesis of extracellular ribonuclease by Bacillus pumilus]

Conditions for the biosynthesis of alkaline extracellular ribonuclease by Bacillus pumilus were studied and their comparison with that of the biosynthesis of ribonuclease by Bacillus intermedius was made. It was estimated that ribonuclease of Bacillus pumilus is synthesized post-exponentially, its synthesis is inhibited by inorganic phosphate and is stimulated by actinomycin D, as the synthesis of ribonuclease by Bacillus intermedius. At the same time essential differences in dynamic of enzyme formation, extent of phosphate inhibition and spores forming conditions of the comparing cultures were found.
