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

摘要

ABSTRACTA bacterial composition contains as anactive biocomponent the strain Pseudomonas putida-36deposited under No. B-2443, and a mineral componentwhich contains the following mixture of salts, inpercent 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. Theweight ratio of the biocomponent to the mineral com-ponent is from 1 to 26-32. The content of livingcells in the biocomponent is from 1.8 x 1010 to3.6 x 1012 per 1 g of dry biomass. The number ofcells of the biocomponent is from 104 to 106 per 1 ml.The concentration of the mineral component is from0.07 to 0.08% by weight. The composition may be usedeither with or without a carrier which may includea solid inert material or water. A method for therecovery of water or soil by treating them with theabove bacterial composition in an amount of 350 to800 mg per 1 m2 of the surface to be treated.
