Abstract
The present invention relates to the field of bio-technologies and environmental protection, and refers the cleaning of water, soil and other media polluted with petroleum products. The cleaning method of the present invention is carried out with a biological preparation that comprises a pool of yeast of the Candida maltosa genus from the strains deposited under No. VKPM Y-2256 and No. VKPM Y-2257. These strains may be present in the pool in any ratio but preferably in the ratio of 1:1. The biological preparation may be used for removing pollution caused by a wide range of hydrocarbons contained in crude oil and petroleum products, for example fuel oil, oils, etc. The biological preparation affords recovery of oil pollution at temperatures up to +41.degree. C. and pH 3.0-9.0, and may be used in saline ecosystems. The process for producing the biological preparation comprises simultaneously cultivating the above-mentioned yeast strains on a liquid medium followed by separation and removal of the biomass thus grown. To obtain a powdered preparation, the biomass is subjected to drying. When cleaning the above-cited media from oil pollution, an aqueous suspension of the biological preparation with a nitrogen-phosphate additive is used.
