摘要：

Molecular weight of PHB becomes low when using a hypochlorite extraction method for PHB separation. This disadvantage was overcome by adding sodium bisulfite which is an anti-oxidant. The molecular weight drop was decreased from 30 % to 14 % by adding sodium bisulfite. It was also found that raising the pH to 12 and the addition of a surfactant resulted in the improvement of the PHB purity.
