The dynamics of the number of bacteria in petroleum contaminated gray forest soil
Journal Title: Problems of Environmental Biotechnology - Year 2012, Vol 2, Issue 1
Abstract
We investigated the dynamics of microorganisms in the gray forest soil contaminated by petroleum products in concentrations from 0 to 20%. Found that the pollution over 7 months was accompanied by increased numbers of ammonifying, mineral and organo phosphate mobilizing, polysaccharide synthesizing microorganisms and decrease the number of nitrifying bacteria. Number of polysaccharide synthesizing bacteria are directly involved in the degradation of petroleum products increased compared to non-contaminated soil at a concentration of 1% oil - 1.78 times at 5% - 33.3, 10% - 60.9, with 20% - 30.8 times. The dependence of the number of autochtonic microorganisms on the concentration of oil comes after a 7-month incubation of contaminated soil. Along with the decrease in the number of autochthonous microbial activity weakened mineralization of humus compounds: oil products at a concentration of 5% - 10.5 times, with a concentration of 10% - 16.8, at a concentration of 20% - to 7.5 times.
