[Preliminary metabolism of D-ribose by Candida bombi]

The activity of D-ribokinase increases and its constitutive synthesis takes place in the yeast Candida bombi after its adaptation to D-ribose. The activity of the enzymes of preparatory metabolism of D-ribose via the reductive pathway after the adaptation to this pentose is low and no growth is found in the medium containing ribitol; therefore, metabolism of D-ribose in C. bombi proceeds via the kinase pathway. D.ribokinase of C. bombi is briefly characterized.
