[Effect of low pH values on the chemical composition of a chemostat culture of Bacillus megaterium]. 1975

Z V Sakharova, and S I Ibragimova

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.

D010710	Phosphates	Inorganic salts of phosphoric acid.	Inorganic Phosphate,Phosphates, Inorganic,Inorganic Phosphates,Orthophosphate,Phosphate,Phosphate, Inorganic
D010743	Phospholipids	Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.
