It has been experimentally established that two strains of bacteria
genus Pseudomonas, isolated from the marine environment and identified
by the fatty acid composition of their cellular lipids as P. fluorescens
ONU328, P. maltophilia ONU329, are not pathogenic and have a
high phenol-oxidizing ability. Bacteria are cultured for two days at a
temperature of 30 °C on MPA, further bacterial cells are suspended in the
mineral medium M-9, and in the optimum amount is introduced into the
contaminated water containing up to 300 mg/l phenol. It was established
that the strain of P. maltophilia possessed a greater phenol-oxidizing
activity than the strain P. fluorescens. When water was treated with strain
P. maltophilia with a culture concentration of 3.5×104 CFU/ml, deep
purification from phenol was observed on 34 day, and with an increase in
the culture concentration to 7.5×105 CFU /ml on 18 day, t=30 °C.
