Microbial oxidation of dimethylnaphthalene isomers.
Three bacterial strains, identified as Alcaligenes sp. strain D-59 and Pseudomonas sp. strains D-87 and D-186, capable of growing on 2,6-dimethylnaphthalene (2,6-DMN) as the sole source of carbon and energy were isolated from soil samples. 2,6-Naphthalene dicarboxylic acid was formed in the culture broths of these three strains grown on 2,6-DMN. In addition, 2-hydroxymethyl-6-methylnaphthalene and 6-methylnaphthalene-2-carboxylic acid were detected in the culture broth of strain D-87. Strain D-87 grew well on 1,2-, 1,3-, 1,4-, 1,5-, 2,3-, and 2,7-DMN as the sole source of carbon and energy and accumulated 2-methylnaphthalene-3-carboxylic acid and 2,3-naphthalene dicarboxylic acid from 2,3-DMN, 4-methylnaphthalene-1-carboxylic acid from 1,4-DMN, and 7-methylnaphthalene-2-carboxylic acid from 2,7-DMN.
