Abstract
Previous study (J. of Chem. Technol. Biotechnol. 2004, 79, 79-84) showed that bacterial cellulose (BC) produced by a bacterial strain JH232 has potential as a source for environmentally friendly ion exchange membranes. In this study, strain JH232 was investigated for phylogenetic classified and characterized for BC production. Comparative analysis of 16S rRNA gene revealed that the strain belongs to the genus Gluconacetobacter. Maximum production of BC was observed when JH232 was cultured in CSL medium (pH 5.5) at $30^{\circ}C$ as determined by flask experiment. When batch and fed-batch cultures of JH232 were performed in the fermenter experiment to compare BC productivity of the strain, BC productivity of fed-batch culture was 1.56 times higher than that of batch culture.
