Study on Characteristics of the Transkelolase Mutant Bacillus subtilis

Abstract

Abstract: C1-B941 is a transketolase mutant of Bacillus subtilis., which is differentiated remarkably with the parent strain C1in the characteristics of cell morphlogy and metabolism. The results showed that: not utilizing pentoses; or weakening thecarbohydrates such as D-glucose utilization or inhibition interaction on carbohydrates ; source there would be defects in synthesisof aromatic amino acids, chains formation during exponential cell growth; and lowering of sporulation capability; It was possibleto accumulate D-ribose in the ferment medium, so as to make the fermented liguid useful in a lorge scale.

Key words: D-ribose-producing strain, Bacillus subtilis, transketolase mutant, propertise
