Rhodococcus biphenylivorans GA1 was successfully isolated, which can efficiently degrade alkali lignin and a variety of lignin-derived aromatic compounds as the sole carbon source. Whole genome sequencing of strain GA1 showed that it possessed G + C content of 68% with the size of 6.0 Mb and 4319 putative open reading frames (ORFs). Four replicons consisting of one circular chromosome (ChrA1) and three circular plasmids (pGA1, pGA2, pGA3) were found. Among these annotated proteins, lignin depolymerizing peroxidases (Dyp) and two lignin-derived aromatic compounds cleavage dioxygenases, protocatechuate 3,4-dioxygenase(P34D) and catechol-1,2-dioxygenase (C12D) play key roles in the catabolism of lignin.
