[The effect of Bacillus intermedius RNAase on the growth and development of Bacillus mucilaginosus].

The effect of Bacillus intermedius RNAase on vegetative cells and spores of siliceons bacteria Bacillus mucilaginosus was investigated. It is shown that the enzyme stimulates the growth of vegetative cells of B. mucilaginosus at a concentration of 10 mkg/ml and promotes germination of spores at a 1000-fold lesser concentration (0.1 mkg/ml). The spores at stages of activation and initiation appear to be most susceptible to the enzyme action. The effect of RNAase on B. mucilaginosus multiplication correlates with intensification of bacterial leaching of bauxites.
