Process for the production of bacterial cellulose

A method for the production of a bacterial cellulose by cultivating a cellulose-producing bacteria for at least a certain period of time under such an apparatus condition that an oxygen-transfer coefficient (K.sub.L a) is about 25 to about 50/hr, said K.sub.L a is determined by using a simulated suspension containing 2% by weight of BC and having a plastic viscosity of 15 to 20 poise.

Cellulose-producing microorganism transformed with a gene for an enzyme

Purine-arabinosides and a method for making purine-arabinosides are disclosed. The method comprises contacting an arabinose donor and a purine source in the presence of an effective amount of enzyme produced by a bacterium and capable of transarabinosylation from the arabinose donor to the purine source, whereby a 9-(.beta.-D-arabinofuranosyl)-purine is produced.

Method for producing purine arabinosides

A method for producing L-proline by fermentation which comprises culturing an L-proline producing mutant in a culture medium until L-proline is accumulated in the culture medium, and recovering the accumulated L-proline; said mutant belonging to the genus Brevibacterium, Corynebacterium or Microbacterium and being resistant to DL-3,4-dehydroproline.
