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.
从当地池塘分离出的甲基obacterium sp. ZP24能够在含有12 g l-1乳糖作为唯一碳源的培养基中生长，在40小时内产生5.25 g l-1的生物量产量，且聚-3-羟基丁酸酯（PHB）含量高达其干重的59%。该分离株还能够利用奶酪乳清并产生1.1 g l-1的PHB。添加硫酸铵使乳清中PHB的产量提高了2.5倍。讨论了甲基obacterium sp. ZP24在从奶酪乳清生产PHB方面的潜力。
