Abstract

A strain of Pseudomonas putida (TMB) was found to resemble P. putida mt-2 (PaW1) in its ability to degrade 1,2,4-trimethylbenzene, toluene, m-xylene, and p-xylene via oxidation of a methyl substituent and reaction of the meta fission pathway, but a different regulatory model is suggested. The ability of P. putida TMB to degrade these substrates was encoded by plasmid pGB (85 kilobase pairs), which showed considerable differences in size, restriction patterns, and DNA sequence from those of plasmid pWWO of strain PaW1.
