Abstract

Microbial genes encoding aromatic ring-hydroxylating oxygenase (ARHOs) have been selected as molecular markers for evaluating the potential of microbial degradation ability in environment. The development of culture-independent metagenomic technology has greatly accelerated the research of functional genes and functional groups on aromatic hydrocarbon degradation in recent years. This article summarized the ARHOs related databases, introduced various functional genes and corresponding primers applied to environment samples in microbial degradation of different types of aromatic hydrocarbons (benzene series, naphthalene as well as other polycyclic aromatic hydrocarbons). It also reviewed the applications of this technology in various complex environment samples. Furthermore, the future development of microbial degradation of aromatic compounds using metagenomics technologies was prospected.

Key words： aromatic compounds microbial community functional genes ring-hydroxylating oxygenases metagenomics technology
