BACTERIAL COMPOSITION FOR THE RECOVERY OF OIL-POLLUTED WATER AND SOIL AND A METHOD FOR THE RECOVERY OF WATER AND SOIL

摘要

A bacterial composition contains as an active biocomponent the strain Pseudomonas putida-36 deposited under No. B-2443, and a mineral component which contains the following mixture of salts, in percent by weight: 34.26 - 37.12 of KNO3, 28.66 - 31.28 of NH4Cl, 25.42 28.71 of NH4H2PO4, and 2.89 - 11.66 of NH4NO3. The weight ratio of the biocomponent to the mineral component is from 1 to 26-32. The content of living cells in the biocomponent is from 1.8 x 1010 to 3.6 x 1012 per 1 g of dry biomass. The number of cells of the biocomponent is from 104 to 106 per 1 ml. The concentration of the mineral component is from 0.07 to 0.08% by weight. The composition may be used either with or without a carrier which may include a solid inert material or water. A method for the recovery of water or soil by treating them with the above bacterial composition in an amount of 350 to 800 mg per 1 m2 of the surface to be treated.
