The process of benzoate degradation by strain Rhodococcus opacus 1CP after a five-year dormancy was investigated and its peculiarities were revealed. The strain was shown to be capable of growth on benzoate at a concentration of up to 10 g L(-1). The substrate specificity of benzoate dioxygenase (BDO) during the culture growth on a medium with a low(More)
Dioxygenases induced during benzoate degradation by the actinobacterium Rhodococcus wratislaviensis G10 strain degrading haloaromatic compounds were studied. Rhodococcus wratislaviensis G10 completely degraded 2 g/liter benzoate during 30 h and 10 g/liter during 200 h. Washed cells grown on benzoate retained respiration activity for more than 90 days, and a(More)
The effects of stress factors (drying, low temperature, and long-term storage) on the survival of the actinobacteria Gordonia polyisoprenivorans 135, which is used as a biosensor receptor to detect sodium benzoate in water solutions, were studied, as well as the effects of these factors on the biodegradation of aromatic compounds. The cells remained viable(More)
Benzoate 1,2-dioxygenase (BDO) of Rhodococcus opacus 1CP, which carried out the initial attack on benzoate, was earlier shown to be the enzyme with a narrow substrate specificity. A kinetics of interaction between benzoate 1,2-dioxygenase and substituted benzoates was assessed taking into account the enlarged list of the type of inhibition and using whole(More)
Ability of actinobacteria Rhodococcus opacus 1CP to survive under unfavorable conditions and retain its biodegradation activity was assessed. The morphological and ultrastructural features of R. opacus 1CP cells degrading benzoate in the presence of oxidants and stress-protecting agents were investigated. The cells of R. opacus 1CP were resistant to(More)
