FIELD: chemistry.
SUBSTANCE: to activate dry form of biopreparation for purification of petropolluted soils water suspension with inducer of enzyme systems id prepared. as water solution for preparation of working suspension of activated biopreparation with concentration of microorganisms not less than 5×107 CFU/ml solution, containing 1 g/l of tripton, 2.5 g/l of glucose, 1 g/l of yeast extract and 1.5 g/l of ammonium sulfate, is used. As inducer of enzyme systems 5 ml/l of Diesel fuel are used. Solution is bubbles with air aeration 1 l/min per I l of solution for 14-18 h without thermostatting.
EFFECT: increased concentration of microorganisms in water suspension and increase of petroleum destruction efficiency.
