Doroshenko I. Microflora of the systems of the hydrobiological cleaning of marine waters

The role and functions of periphyton microorganisms of technical construction - hydrobiological system for cleaning of polluted waters placed in Oil Harbour (Sevastopol Bay, Black sea) are studied. It's shown that total quantity of heterotrophic bacteria in periphyton changes from 104 to 107 cell/g. The quantity of other groups varies from 10 to 106 cell/g. The quantity of heterotrophic bacteria in area of hydrobiological system placing is decreased by 4 - 5 orders as compared with periphyton's quantity. This fact has reflected the law of bacteria expansion in sea water. From peryfiton 155 cultures of bacteria are selected. From those cultures prevailed the bacteria Vibrio - 36 %, 22 % cultures Marinococcus, and 19 % - Pseudomonas, 16 % - Microbacterium. Yeasts (66 cultures) from the periphyton systems of the hydrobiological cleaning are first selected. The dominant representatives species composition were determined according to modern nomenclature: Candida lambica - 26 %, Candida krusei - 24 % and Rhodotorula mucilaginosa - 22%. The sea yeasts ability to grow on media with high concentrations of the diesel fuel was evaluated.
