Abstract
Inhibition of the growth of Bacillus megaterium was studied in the conditions of chemostat. Inhibition of the growth by hydrogen ions had almost no effect on the content of DNA, RNA, protein and polysaccharides, but the protein-synthesizing activity of RNA changed. The content of polyphosphates, of high and low molecular weight, depended on pH; the relationship was of a non-linear character. The total content of lipids increased with the concentration of hydrogen ions.
摘要
在恒化器条件下研究了巨大芽孢杆菌生长的抑制情况。氢离子对生长的抑制对DNA、RNA、蛋白质和多糖的含量几乎没有影响，但RNA的蛋白质合成活性发生了变化。高分子量和低分子量聚磷酸盐的含量取决于pH值；这种关系呈非线性。脂质的总含量随着氢离子浓度的增加而增加。
