Title: Novel biphenyl-oxidizing bacteria and dioxygenase genes from a korean tidal mudflat.

Authors: Lee, Tae Kwon; Lee, Jaejin; Sul, Woo Jun; Iwai, Shoko; Chai, Benli; Tiedje, James M; Park, Joonhong

Published In Appl Environ Microbiol, (2011 Jun)

Abstract: Gene-targeted FLX titanium pyrosequencing integrated with stable isotope probing (SIP) using [(13)C]biphenyl substrate revealed that tidal mudflat sediments harbor novel aromatic ring hydroxylating dioxygenases (ARHD). More than 80% of the detected ARHD genes comprise four clades (0.5 distance) with 49 to 70% amino acid identity to sequences in public databases. The 16S rRNA sequences enriched in the (13)C fraction were from the Betaproteobacteria, bacilli (primarily Paenibacillus-like), and unclassified phyla.
