title: Cultivation of the bacterial strain Achromobacter delicatulus, producing an exocellular polyglucan-type polysaccharide in the fermentation tank FU-6.
abstract: Growth processes and biosynthesis of the exocellular polyglucan-type polysaccharide, produced by the bacteria Achromobacter delicatulus, were studied in the laboratory fermentation apparatus FU-6 under three completely different aeration systems. The purpose of this study was to find the most economical way of the polysaccharide biosynthesis. The growth rate and the synthesis of the exopolysaccharide were not limited either by the oxygen transfer or glucose content under the conditions examined. The best construction proved to be the fermentation tank with the lowspeed agitation system. In the case of the bacterial strain Achromobacter delicatulus, producing huge amounts of the thick slimy polyglucan exopolysaccharide, the industrial production may develop without any principal technical difficulties.
