Abstract
|
|
|
|
Acetobacter strains are bacteria that can synthesize cellulose when grown on an undefined medium containing glucose. Several culture conditions affecting cellulose production by Acetobacter sp. A9 were examined by cultivating cells under shaking cultures. The addition of buffering agents, such as 3-(N-morpholino) propanesulfonic acid (MOPS) and CaCO3, increased cellulose production. It suggests that pH of culture medium is important to an economical mass cellulose production. Addition of bead (Φ10 mm) to culture medium stimulated ’disintegrated bacterial cellulose’ production.
