Degenerate primers as biomarker for gene-targeted metagenomics of the catechol 1, 2-dioxygenase-encoding gene in microbial populations of petroleum-contaminated environments
Catechol 1, 2-dioxygenase (1, 2-CTD) plays an important role in the biodegradation of most aromatic pollutants (e.g. phenol) by cleaving the bond between the phenolic hydroxyl groups. In this study, we analyse...
