Abstract
Bacteria are good source for production of various important biopolymers like alginate
and poly β-hydroxybutyrate (PHB). In the present study twenty four different
exopolysaccharide overproducing bacterial cultures were evaluated for their maximum
potential for alginate and PHB production. Maximum yield of exopolysaccharides (3.9
g/l) and alginate (3.3 g/l) was obtained in Azotobacter chroococcum culture CBD13.
While maximum yield of PHB (22.6 mg/l) was obtained in A. choococcum culture H15.
Minimum yield of exopolysaccharides (1.3 g/l) and alginate (0.8 g/l) was obtained in
bacterial culture L65. While no PHB production was observed in case of A. choococcum
culture H11. In most of the cases with an increase in exopolysaccharide production,
there was also an increase in alginate production.
