Abstract
Methylobacterium sp. ZP24, isolated from a local pond, is able to grow in a medium containing 12 g l−1 lactose as a sole source of carbon, giving 5·25 g l−1 biomass yield and poly-3-hydroxybutyrate (PHB) up to 59% of its dry weight in 40 h. The isolate was also able to utilize cheese whey and produce 1·1 g l−1 PHB. Addition of ammonium sulphate increased the production of PHB from whey 2·5-fold. The potential of Methylobacterium sp. ZP24 in PHB production from cheese whey is discussed.Keywords
