[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. Certain concentrations of the d2 factor can also potentiate yeast growth. The effect is more pronounced if the d2 factor and RNase are added in combination rather than singly. Although the cell membrane is a target for both d2 factor and RNase, the mechanisms of their action are presumably different.
