doi:10.3321/j.issn:1000-7091.2002.02.028

Abstract

Abstract: St rain A6 (Gluconobacter sp. ) w hich can convert D-glucose to 2, 5-diketo-D-gluconate w as obtained f rom f ruit, vegetable and soil samples. Strain A6 accumulated 17210 mg of 2, 5-diketo-D-gluconate calcium in 1 mL culture containing 25% D-g lucose and 10% CaCO3(W/ V) af ter 7 days. cult ivation at 28 e , w ith a y ield of 52105 mol% . The glucose tolerance of this strain exceeds that of other strains reported in China.

Key words: St rain, 2, 5-diketo-D-gluconate, Yield, Glucose tolerance
