| The development of bacteria (total quantity of heterotrophs and hydrocarbon-oxidizing bacteria)and Protozoa in the ground, bottom water layer with oil added and without it was studied under experimental conditions as influenced by Nereis diversicolor O. F. Muller. It was observed that the bacteria quantity rose in the ground, dropped in the bottom water layer, except for the hydrocarbon-oxidizing bacteria in oiled water, where their quantity grew one order higher. Infusoria were not discovered in the ground. An increase of their quantity in the bottom water layer was statistically significant in all variants of the experiments, and was accompanied by changes in the species composition. |
