Cellulose production from glucose using a glucose dehydrogenase gene (gdh)-deficient mutant of Gluconacetobacter xylinus and its use for bioconversion of sweet potato pulp.

Abstract excerpt

A gene fragment encoding a putative pyrroloquinoline quinone glucose dehydrogenase (PQQ GDH) was cloned from a bacterial cellulose (BC)-forming acetic acid bacterium, Gluconacetobacter xylinus (=Acetobacter xylinum) strain BPR 2001, which was isolated as a high BC producer when using fructose as the carbon source. A GDH-deficient mutant of strain BPR 2001, namely GD-I, was then generated via gene disruption using...
