MICROORGANISMS OF OIL POLLUTED SOILS RECULTIVATED BY CAREX HIRTA

2009

It has been conducted monitoring for the natural self-recovery of oil polluted loamy grounds by soil microorganisms as a basic factor and observing for recovering process in the soils recultivated by Carex hirta. Quantity of microorganisms most of the investigated physiological groups was reduced in the first months after oil pollution, the intensific development of hydrocarbon-utilizing microorganisms in ground was observed at the same time. The positive effect of C. hirta on the processes of microorganisms growth most of physiological groups and microbial destruction of hydrocarbon was revealed in the first months after oil pollution. Quantity of microorganisms of all physiological groups practically completely recovering and hydrocarbon contents in soil was remained in 18 months after oil pollution. An oil-resistant and long-rooted plant C. hirta favours the intensific development of oil-destructive microorganisms іn polluted soil and accordingly positively influences on the level of microbial destruction of oil hydrocarbons. Using of C. hirta and microorganisms in complex of bioremediation measures is a perspective method for soil purification from oil contamination.
