Polyhydroxybutyrate production using agro-industrial residue as substrate by Bacillus sphaericus NCIM 5149

The aim of this work was to study the production of polyhydroxybutyrate (PHB) using agro- industrial residues as the carbon source. Seven substrates, viz., wheat bran, potato starch, sesame oil cake, groundnut oil cake, cassava powder, jackfruit seed powder and corn flour were hydrolyzed using comme...

Summary:The aim of this work was to study the production of polyhydroxybutyrate (PHB) using agro- industrial residues as the carbon source. Seven substrates, viz., wheat bran, potato starch, sesame oil cake, groundnut oil cake, cassava powder, jackfruit seed powder and corn flour were hydrolyzed using commercial enzymes and the hydrolyzates assessed for selecting the best substrate for PHB production. Jackfruit seed powder gave the maximum production of PHB under submerged fermentation using Bacillus sphaericus (19%) at the initial pH of 7.5.
