The production of polyhydroxyalcanoates (PHAs), which are biodegradable plastics, was studied using milk whey and dairy wastewater activated sludge to define a suitable C/N ratio, the pre-treatments required to reduce the protein content, and the effect of pH correction. The results show good production of PHAs at a C/N=50 and without pH correction. The use of dairy wastewater activated sludge has the advantage of not requiring aseptic conditions.
聚羟基烷酸酯（PHA）是一种可生物降解的塑料，本研究使用乳清和乳制品废水活性污泥来确定合适的 C/N 比、降低蛋白含量所需的预处理以及 pH 值校正的影响。结果表明，在 C/N=50 且无需 pH 值校正的情况下，PHA 的产量较好。使用乳制品废水活性污泥的优点是无需无菌条件。
