Shedding light on anaerobic benzene ring degradation: a process unique to prokaryotes?

Nonaromatic Products from Anoxic Conversion of Benzoyl-CoA with Benzoyl-CoA Reductase and Cyclohexa-1,5-diene-1-carbonyl-CoA Hydratase

“…Although the hex-1-ene (compound 6) and the 2-hydroxyhexane compound (compound 7) may play an important role in the aromatic metabolism of R. palustris (3,22), their formation in T. aromatica appears as an in vitro effect without metabolic relevance.…”

“…The discrepancy to our results might have different reasons. Either benzoyl-CoA reduction proceeds via different mechanisms in R. palustris as discussed elsewhere (3,22), or the diene isomers detected by GC/MS were artificially formed during derivatization of the products.…”

“…1, compound 1) has been identified as a central intermediate in anoxic degradation of many aromatic substrates (for review see Refs. [1][2][3][4].…”

Anaerobic Degradation of Aromatic Compounds byMagnetospirillumStrains: Isolation and Degradation Genes

“…This benzoyl-CoA pathway is shared by the genera Thauera, Azoarcus, and Rhodopseudomonas with slight variations. 1,4,7) On the other hand, strict anaerobic iron-and sulfatereducing and syntrophic bacteria have also been found to degrade aromatic compounds. Their degradation pathways are now being investigated.…”

Experimental Study on Micro-Biological Degradation of 1,3,5-TMB in Groundwater

“…INTRODUCTION 1,3,5-TMB (trimethylbenzene) is one of primary constituents of petroleum and considered to be priority pollutant due to the high toxicity, carcinogenicity and mutagenic activity. Contamination of groundwater with the benzene compounds is difficult to be remedied because they are relatively water-insoluble and can diffuse rapidly once introduced into aquifers [1], [2].…”
