细菌纤维素高产菌的选育

Breeding of High Cellulose-Producing Strain──Acetobacter Xylinum

以木醋杆菌为出发菌株，通过紫外诱变的手段，获得一株产酸减少，纤维素产量提高，产纤维素较稳定的菌株UV3，纤维素产量由6g／L（干重）提高到10g／L（干重）。

A cellulose - producing strain Acetobacter xylinum, was mutagenized by ultraviolet rays .The mutant Acetobacter xylinum strain UV3 was obtained. UV3 produces less acid and more cellulose than the wild - type strain. Dry weight of bacterial cellulose was inereased from 6 g/L to10 g/L.
