Abstract:
Oxygenases play a key role in degradation of the aromatic compounds in the wastewater. This study explores the oxygenase coding gene sequences from the metagenome of activated biomass. Based on these results, the catabolic capacity of the activated sludge was assessed towards degradation of naphthalene, anthracene, phenol, biphenyl and o-toluidine. Oxygenases found in this study were compared with oxygenases from three other metagenome datasets. Results demonstrate that despite different geographical locations and source, many genes coding for oxygenases were common between treatment plants. 1, 2 Homogentisate dioxygenase and phenylacetate CoA oxygenases were present in all four metagenomes. Metagenomics provides a vast amount of data that needs to be mined with specific targets to harness the potential of the microbial world.
