Isolation and Properties of Mutants of Zymomonas mobilis Deficient in Sugar Assimilation.
An enrichment method using d-cycloserine was designed for the isolation of spontaneous mutants of Zymomonas mobilis deficient in glucose or fructose utilization. The mutants could easily be isolated since they represented 80 to 90% of the population after two and three enrichment cycles. Glucokinase and fructokinase activities in the mutants were affected.
