Abstract
A process for the production of extra-cellular microbial cellulose having the following 4 steps: (a) a growth step in which a bacterium in cultured in stirred batch culture until the carbon source present is substantially exhausted, (b) an accumulation step in which the carbon source is supplied continuously to the culture, (c) a removal step and (d) a separation step. The microbial cellulose produced by the process is readily usable as a bulking agent in foods or as a tabletting aid.
