[Effect of carbon, nitrogen, and phosphorus sources of nutrition on the growth of R-, S- and M-dissociants of Pseudomonas aeruginosa].
The effect of glucose, nitrate, and phosphate on the stationary-phase growth parameters of the R, S, and M dissociants of the hydrocarbon-oxidizing bacterium Pseudomonas aeruginosa K-2 was studied. The data obtained were analyzed in terms of the Mitscherlich equation. S dissociant required less glucose than other dissociants, whereas M dissociant required less nitrogen and phosphorus. These findings were confirmed by the results of investigation of the combined action of glucose, nitrate, and phosphate in a 3 x 3 x 3 factor experiment. It is anticipated that M dissociant must prevail under conditions of nitrogen and phosphorus deficiency, and S dissociant must be dominant in the case of optimally chosen proportions between the biogenic elements studied.
