The bacterium, Burkholderia (previously Pseudomonas) sp. strain PS12, reported earlier to degrade 1,2,4-trichlorobenzene is shown here to utilize also 1,2,4,5-tetrachlorobenzene (Cl4-benzene) as a growth substrate. To investigate the possibility that this organism attacks Cl4-benzene with a chlorobenzene dioxygenase which concomitantly causes dehalogenation, and to analyze the substrate range of the initial enzyme, a 5503-bp DNA fragment from PS12, exhibiting high similarity to genes coding for… CONTINUE READING
