Safety of the oil destructor microorganism as a component of a new biological preparation for the main links of marine model hydrobiocenoses

Due to the active development of marine transportation infrastructure and possible occurrence of accompanying hydrocarbon pollution, there is a need to develop new safe methods of both direct elimination of pollution and its consequences. One of the promising and safe ways is the use of products based on oil-degrading microorganisms. In this work the influence of Arthrobacter psychrochitiphilus ARC 42 strain on the main links of marine ecosystems is considered. It was found that the studied strain did not inhibit the development of saprophytic microbiota, in high concentrations influenced the development of phytoplankton culture, practically had no effect on benthic organisms. Strain ARC 42 in the recommended concentrations is safe for fish and does not affect their physiological parameters. Experiments with the addition of oil revealed the absence of toxicity of its decomposition products, which confirms the safety of using the preparation based on this strain.
