[Effect of phosphorylated constituents on the growth of Pseudomonas fluorescens in media containing potassium oxalatoberyllate].

Differences in the extent of beryllium inhibition on the growth of Pseudomonas fluorescens cultivated in various media are related to the concentration and nature of phosphorus-containing constituents of the substrate. Quantitative studies are carried out for interaction processes leading to reduction in beryllium toxicity. These include sequestration of beryllium in soluble form by beta-glycerophosphate and formation of sparingly soluble derivatives with inorganic orthophosphate ions.
