ABSTRACT
Deinococcus radiodurans is extremely resistant to ionizing and UV irradiation. The addition of manganese(¢º) into stationary-phase culture can trigger a new cycle of cell division ( Mn-CD effect ). Although D.radiodurans can hardly utilize sugar , but it does can incorporate glucose and fructose into the cell mass. We found that D. radiodurans can metabolize sugar by glycolysis ( EMP ) and pantose phosphate pathway ( PPP ). The activity of both pathways would be altered by the addition of manganese(¢º). The marker enzymes of the PPP ( transketolase ) and EMP pathway ( aldolase ) were also analyzed. Results show that manganese(¢º) can induce the hydrolysis of glucose by activating the EMP pathway. However , the induction effect various with different cultural conditions. In analyzing the PPP pathway , the activities of transketolase were also various with different cultural conditions.
