Degradation of mono- and polyaromatic hydrocarbons by a new gram-positive bacterial stain

A gram-positive bacterial stain was isolated from soil of industrial impact. Strain was identified as Rhodococcus sp. B7a. The strain was utilizing substituted and non-substituted mono- and polyaromatic hydrocarbons. The strain was able to growth on 2- and 4-chlorobenzoic acids. The para-hydroxybenzoate and protokatechuate were metabolites of 4-chlorobenzoate by strain Rhodococcus sp. B7a. The strain demonstrates a high degrade activity to ortho- and para-substituted mono-, di- and three- chlorinated biphenyls
