| 摘要 |
FIELD: biotechnology, industrial microbiology, ecology. ^ SUBSTANCE: invention relates to a biological preparation used in treatment of soil polluted with petroleum and oil products in simultaneous recovery of its physicochemical properties and natural biocenosis. The biopreparation-petroleum destructor comprises microorganism culture and bacterial fertilizer as fermented bedding avian dung containing the following native microorganisms: Clavibacter michiganese, Bacillus amyloliquefaciens and Micrococcus varians. As a microorganism culture the strain Bacillus cereus 3K is used with a titer value 1012 cells/g of bacterial fertilizer. Invention provides enhancing petroleum-destructing activity, to simulate development of petroleum-oxidizing microflora, to increase the rate of petroleum decomposition, to provide intensification of bacterial processes recovering agrochemical properties of soil, to carry out treatment of petroleum-polluted soils in regions with short heat period. ^ EFFECT: improved, enhanced and valuable properties of agent. ^ 6 tbl, 7 ex |
