ABSTRACT

The purpose of screening paraffin oxidizing microorganisms and optimization of culture conditions on n-paraffins and oil products. The study on the ability to use hydrocarbons separated fungus culture that morphological characteristics attributed to the genus Aspergillus. The features Aspergilluss growth on hydrocarbons, the optimization of cultivation on hydrocarbons in a laboratory fermenter. It was shown that the lag phase duration and duration of fermentation depends on the accumulation of monocarboxylic acids. The duration of the lag phase of the fungus on a medium with paraffins was 10 hours.
The duration of the lag phase is reduced by the introduction of 0.2% on oxidants obtained by ozonation n-paraffins. In the result of study was concluded that on the medium with 4% oil of biomass up to 150%. Probably the selected culture can be used to produce protein-containing feed and for cleaning oil products from water and soil.

Keywords: Bioremediation, bacteria Candida, Aspergillus sp., lag-phase, growth medium.
