Cellulose production by Gluconacetobacter hansenii in a medium containing ethanol

Article

Abstract

The addition of 1% (v/v) ethanol to the basal medium inhibited growth of Gluconacetobacter hansenii but decreased the numbers of non-cellulose producing cells. Cellulose production increased 1.7 times to approx. 2.5 g l−1 and showed a pattern of mixed growth-associated production. Microbial cells produced rigid pellicle-type bacterial cellulose as the shell of a large lump of bacterial cellulose like a static culture. The inoculum cultivated for 3 d maintained cellulose production by the fifth batch.
