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.
从土壤样品中分离出三株细菌菌株，分别鉴定为产碱杆菌属菌株D-59和假单胞菌属菌株D-87及D-186，它们能够以2,6-二甲基萘（2,6-DMN）作为唯一碳源和能源生长。在以2,6-DMN为碳源生长的这三株菌株的培养液中形成了2,6-萘二甲酸。此外，在菌株D-87的培养液中检测到了2-羟甲基-6-甲基萘和6-甲基萘-2-羧酸。菌株D-87能够以1,2-、1,3-、1,4-、1,5-、2,3-和2,7-DMN作为唯一碳源和能源良好生长，并从2,3-DMN中积累2-甲基萘-3-羧酸和2,3-萘二甲酸，从1,4-DMN中积累4-甲基萘-1-羧酸，从2,7-DMN中积累7-甲基萘-2-羧酸。
