CHARACTERISATION OF A MEMBER OF THE GENUS CELLULOSIMICROBIUM AS A DEGRADER OF 2,4-DICHLOROPHENOXYACETIC ACID

On the basis of the cultural, morphological, physiological and biochemical features, the taxonomic position of the NPZ-121 strain (isolated from the soil contaminated with chemical waste in Ufa (Russia)) as belonging to the species Cellulosimicrobium funkei was specified. In a batch culture the dynamics of growth of the strain C. funkei NPZ-121 and utilization of 2,4-dichlorophenoxyacetic acid at a concentration of 100 mg/l were described. For 11 days the culture used up to 69% of the substrate from the initial value. The ability of the strain to metabolize 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) was revealed previously. Thus, the polysubstrate activity to chlorinated phenoxyacetic acids of the NPZ-121 strain was established.
