Anaerobic degradation of non-substituted aromatic hydrocarbons

Highlights ► Anaerobic benzene and naphthalene degradation is performed by microbes belonging to different phyla. ► Metabolite analysis of cultures suggest as initial activation reaction either methylation, hydroxylation, or carboxylation for benzene, and methylation or carboxylation for naphthalene...

Zusammenfassung:	Highlights ► Anaerobic benzene and naphthalene degradation is performed by microbes belonging to different phyla. ► Metabolite analysis of cultures suggest as initial activation reaction either methylation, hydroxylation, or carboxylation for benzene, and methylation or carboxylation for naphthalene. ► Proteogenomic studies indicate carboxylation of benzene and naphthalene. ► Non-substitute aromatic hydrocarbons are most likely activated by a novel carboxylation reaction.
