[Storage of Pseudomonas strains degrading the surfactants].

The survival rate and the destruction activity of Pseudomonas strains decomposing anionic and ampholytic surfactants were studied in the course of their storage for a long period of time. The strains were shown to remain viable and active after being freeze-dried for a year. Therefore, lyophilisation can be recommended as the main method of storage for bacterial strains decomposing the following surfactants: sulfoethoxylate, sulfonate, cyclimide, and amidobetaine.

[Bacterial destruction of anionic sulfoethoxylate surfactants].

A Pseudomonas putida strain G was isolated and its activity in the destruction of sulfoethoxylates (surfactants) was studied as a function of the cultivation conditions. Ultrastructural changes were found in the cells utilizing sulfoethoxylates. Sulfoethoxylates were found to be decomposed by P. putida G via two pathways: (a) desulfation of the molecule and (b) cleavage of the alkyl ester bond. The intermediate products were not toxic and did not pollute the habitat. The strain can be used for microbiological purification of sewage.
