The present investigation gives an insight on the potential of food and kitchen waste as a suitable feed stock for the production of biopolymer, biofuels, enzymes and chemicals. Media engineering improved poly-3-hydroxybutyrate (PHB) production from 0.91 g/L to 5.132 g/L. There is a five-fold increase in PHB production. The food and kitchen waste was also evaluated for the production of bioethanol, 2, 3 - butanediol, and pectinase. Saccharomyces cerevisiae produced 0.316 g of bioethanol, Bacillus sonorensis MPTD1 produced 2.47 (µM/mL)/min of pectinase and Enterobacter cloacae SG1 produced 3 g/L of 2, 3-butanediol with a productivity of 0.03 g/L/h using food and kitchen waste as carbon source. Targeting on multiple value added products will improve the overall process economics.
本研究探讨了食品和厨房垃圾作为生物聚合物、生物燃料、酶和化学品生产合适原料的潜力。通过介质工程，聚-3-羟基丁酸酯（PHB）的产量从 0.91g/L 提高到 5.132g/L，产量增加了五倍。还评估了食品和厨房垃圾生产生物乙醇、2,3-丁二醇和果胶酶的潜力。酿酒酵母产生了 0.316g 生物乙醇，Bacillus sonorensis MPTD1 产生了 2.47（µM/mL）/min 的果胶酶，肠杆菌 cloacae SG1 利用食品和厨房垃圾作为碳源生产了 3g/L 的 2,3-丁二醇，产率为 0.03g/L/h。针对多种高附加值产品将提高整个工艺的经济性。
