Biological activity of petropolluted soil when using cryogel

In laboratory experiment biological reaction of the natural and broken soil system at using cryogel as cryoprotector is defined. Lack of significant quantitative and qualitative physiological reaction of test-culture regardless of concentration of cryogel against various oil pollution is found out. Change of microbial biomass volimes is recorded at similar concentration of cryogel and naphtha of 20%. In all other variants the dynamics of microbial mass is ambiguous.
