| Abstract |
| Marine methanotrophs, Methylobacter marinus could be first cultured and grown in no-salt medium. Here, we examined the synergistic effects of a microbial consortium composed of Methylobacter (42%) and Methylophilus (43%) genera (Methylobacter marinus, Methylophilusflavus, and Methylophilusrhizosphaerae) in simultaneous aerobic denitrification and biodegradation of polycyclic aromatic hydrocarbons (PAHs) using the interactions among different species. We confirmed that the Methylobacter and Methylophilus consortium increased the efficiency of aerobic denitrification and biodegradation of PAHs. Methane monooxygenase (MMO) induced the most potent cometabolism in the PAH oxidation chain by methanotrophs via this mechanism, and dehydrogenation by methanol dehydrogenase (MDH), formaldehyde dehydrogenase (FADH), and formate dehydrogenase (FDH) was thought to promote the codegradation of anthracene and phenanthrene. These data confirmed the synergistic effects of coexistence of Methylophilus species, which are dependent on methanol, and Methylobacter species, which produce methanol, in the biodegradation of anthracene and phenanthrene. |
