The anaerobic degradation of polycyclic aromatic hydrocarbons (PAH) has only recently been described for naphthalene and acenaphtene in water saturated microcosms and under denitrifying conditions, although no metabolites were determined.92,93 Respectively 2-ethylphenol94 and p-cresol95 were identified as metabolites from naphtalene degradation in methanogenic microcosms presumably as the result from ring reduction and reductive ring fission. Biphenyl degradation has only been demonstrated under aerobic conditions, except for 2-hydroxybiphenyl. Suflita et al.96 showed that aquifer-derived inoculum degraded the substituted biphenyl under sulfate-reducing conditions, as demonstrated by electron donor/acceptor stoichiometry. However, metabolism of 2-hydroxybiphenyl was isomer specific; neither meta- nor para-hydroxylated biphenyls could be degraded.

HbpR regulatory protein is used to detect 2-hydroxybiphenyl, biphenyl and other two-ring aromatic compounds. The biosensing strains carrying such vector were developed to detect and quantify 2-hydroxybiphenyl and biphenyl levels, where the vector contained the fusion of hbpR-hbpC cassette with luxAB or gfp as a reporter gene.[11,19] Detection of 2-hydroxybiphenyl and biphenyl is crucial due to their wide usage in different industrial products. Source of HbpR protein was Pseudomonas azelaica HBP1 strain having 2-hydroxybiphenyl and 2,2-dihydroxybiphenyl biodegradation pathway (hbpCAD genes), which is regulated by HbpR protein.[20–24]
