Abstract

Marine bacterial strains (BP-PH, CAR-SF, and DBF-MAK) were isolated using biphenyl, carbazole (CAR), or dibenzofuran (DF) respectively as substrates for growth. Their 16S ribosomal DNA sequences showed that the species closest to strain BP-PH, strain CAR-SF, and strain DBF-MAK are Alteromonas macleodii (96.3% identity), Neptunomonas naphthovorans (93.1% identity), and Cycloclasticus pugetii (97.3% identity), respectively. The metabolites produced suggested that strain CAR-SF degrades CAR via dioxygenation in the angular position and by the meta-cleavage pathway, and that strain DBF-MAK degrades DF via both lateral and angular dioxygenation. Polychlorinated biphenyl (KC-300) and 2,3-dichlorodibenzo-p-dioxin were partially degraded by strain BP-PH and strain DBF-MAK, while 2,7-dichlorodibenzo-p-dioxin and 2,4,8-trichlorodibenzofuran remained virtually unchanged.
