Novel Biphenyl Oxidizing Bacteria and Dioxygenase Genes from a Korean Tidal Mudflat
16S rRNA genes from SIP-generated DNA(C12) of Korean tidal mudflat
Gene-targeted FLX titanium pyrosequencing integrated with 13C-stable isotope probing (SIP) revealed that tidal mudflat sediments harbor for novel aerobic biphenyl degradative bacteria and aromatic ring hydroxylating dioxygenases (ARHD). Known terrestrial biphenyl oxidizing bacteria and dioxygenase genes were rare in 13C-biphenyl enriched bacterial community. Instead, more than 80% of the detected ARHD genes are not in the public databases.
