Abstract

Abstract:

Wounded fruits were used as raw materials to isolate and obtain a cellulose-producing strain, G-29, with high productivity and genetic stability through static enriching culture and repeated screening. The morphology, physiological and biochemical characteristics and 16S rDNA sequence of G-29 were analyzed. This strain was identified to be a new subspecies of Gluconacetobacter intermedius in the species of Gluconacetobacter. This strain has been preserved in China Center for Typical Culture Collection (CCTCC) with the collection number of CCTCC NO: M208234.

Key words: bacterial cellulose, Gluconacetobacter, physiological and biochemical characteristics, identification
