[The use of pancreatic RNAse in the production of baker's yeast].

Microdoses of a preparation of pancreatic RNase were shown to stimulate the growth of Saccharomyces cerevisiae yeast. The effect was only retained at a certain inoculum/enzyme preparation ratio. Industrial tests of the preparation showed that the addition of RNase to the first reservoirs for culture accumulation (an inoculator and a seeding device) increased the yield of bakers' yeast and improved their quality.

[Effect of Bacillus intermedius RNAase on growth of a Saccharomyces cerevisiae culture].

The effects of RNase from Bacillus intermedius on proliferation of Saccharomyces cerevisiae were studied. The enzyme (0.01 microgram/ml) stimulated the yeast cell budding.

[Effect of membranotropic physiologically-active substances on the growth of Saccharomyces cerevisiae cultures].

The effect of Bacillus intermedius RNase and yeast autoregulatory d2 factor on growth of Saccharomyces cerevisiae is reported. It is shown that 0.01 microgram/ml of RNase stimulates the growth of the yeast on malt wort and molasses, the peak of the effect being observed for the enzyme added in the middle exponential phase.
