МИКРОБИОЛОГИЧЕСКАЯ ХАРАКТЕРИСТИКА ДОННЫХ ОСАДКОВ ЗАПАДНОГО ШЕЛЬФА ЧЕРНОГО МОРЯ

Certain aerobic and anaerobic groups of microorganisms in bottom sediments of the western shelf of the Black Sea are studied for their quantity. Heterotrophic microorganisms are found in all silt samples. The hydrocarbon-oxidizing and sulphate-reducing bacteria are not found in deep-water stations remoted from the shore. Their highest quantity is observed along the section of penetration of the Kamchiy river waters. The groups of lipolytic and denitrifying microorganisms are confined to bottom sediments of the littoral and harbour stations which are subjected to the anthropogenic action most of all.
