Coexistence of two distinct copies of naphthalene degradation genes in Pseudomonas strains isolated from the western Mediterranean region

Appl Environ Microbiol. 2002 Feb;68(2):957-62. doi: 10.1128/AEM.68.2.957-962.2002.

Abstract

We analyzed the occurrence of the naphthalene degradation upper-pathway (nah) genes in the western Mediterranean region. The amplification, restriction, and sequence analysis of internal fragments for several nah genes (nahAc, nahB, nahC, and nahE) from naphthalene-degrading strains isolated from this geographical area proved the coexistence of two distinct sets of nah genes.
