Phenol [Ph] , bromobezene[BrB] , salicylate [Sal] , benzoate [Ben] and gallic Acid [GaA] were tested as sole carbon sources for the growth of the isolated soil strain Corynebacterium sp. It was
found that the isolated strain degraded phenol, gallic acid, benzoate, salicalate and bromobenzene. The optimum carbon concentrations were [0.5-1 g/l] of the aromatic compounds enhanced the growth. On the other hand, the concentration of carbon sources at 5-10 g/l inhibited the growth. The concentration of yeast extract [2 g/l] was effective for the degradation of aromatic compounds. Catechol 1-2 dioxygenase was found in the cells grown on media containing phenol or bromobenzene while protocatechouic 3-4dioxygenase was found in cells grown on media containing salicylate [Sal] , benzoate [Ben] and gallic acid as sole carbon sources which means that ortho cleavage pathway may be present in C orynebacterium sp.
