Enzyme activities have been measured in the partners of a bacterial mating system consisting of the hydrogen autotroph Nocardia opaca (donor and Aut- recipient), the heterotroph Rhodococcus erythropolis (recipient) and intra- and interspecies transconjugants after growth on fructose, pyruvate and under autotrophic conditions. Specific activities of each of(More)
Various strains of Paracoccus denitrificans grown under conditions of unrestricted oxygen supply contained low but measurable activities of fermentation enzymes such as ethanol dehydrogenase and 2,3-butanediol dehydrogenase. However, when the bacteria were subsequently incubated for up to 22 h under restricted aeration conditions permitting respiration(More)
