The effect of the RNase from Bacillus intermedius on the growth and trophic cycle of Candida utilis was studied. The RNase at concentrations of 0.001-0.01 microgram/ml stimulated yeast growth by 30-40% as compared to the control, reduced the mitotic cycle of the yeast by shortening its G1 phase, and decreased the number of exotrophic cells in the G1 phase to a minimum. It was suggested that RNase is involved in the regulation of the transition of cells from the exo- to endotrophic state.
研究了中间芽孢杆菌核糖核酸酶对产朊假丝酵母生长和营养循环的影响。与对照相比，浓度为0.001 - 0.01微克/毫升的核糖核酸酶刺激酵母生长30 - 40%，通过缩短其G1期来缩短酵母的有丝分裂周期，并将G1期外营养细胞的数量降至最低。有人认为核糖核酸酶参与了细胞从外营养状态向内营养状态转变的调节。
