ABSTRACT:
Polysaccharide is produced in good yields with good control by continuous culture of a polysaccharide-producing strain of Azotobacter vinelandii under carbon-limited conditions, preferably with restricted oxygen uptake, with the advantage that the effluents produced are non-polluting having a low biological oxygen demand (B.O.D.).
