Aerobic Growth of Rhodococcus aetherivorans BCP1 Using Selected Naphthenic Acids as the Sole Carbon and Energy Sources [PDF]

open access: yesFrontiers in Microbiology, 2018
Naphthenic acids (NAs) are an important group of toxic organic compounds naturally occurring in hydrocarbon deposits. This work shows that Rhodococcus aetherivorans BCP1 cells not only utilize a mixture of eight different NAs (8XNAs) for growth but they ...

Aromatization of Cyclohexanecarboxylic Acid

open access: yesJournal of Biological Chemistry, 1966
Abstract An enzyme which catalyzes the aromatization of cyclohexanecarboxyl coenzyme A has been isolated from whole liver as well as from liver mitochondria. Incubation of the soluble, partially purified enzyme with cyclohexanecarboxyl-CoA produces cyclohexene-1-carboxyl-CoA, benzoyl-CoA, and a polar compound which has not been further characterized ...
