摘要:
摘要 研究了利用食品废弃物进行厌氧酸化的各种条件.结果表明,当食品废弃物与水的质量比为13、食品废弃物厌氧酸化液pH值为6.5以及酸化温度为30 ℃时,对酸化后废液中各有机酸的产生有利,酸化过程中总有机酸产量最大为25~35 g/L.特别当在食品废弃物厌氧酸化液中加入丁酸梭菌活菌制剂后,酸化过程发生了显著的变化.本文还研究了真氧产碱杆菌(Raltonia eutropha)利用食品废弃物厌氧酸化生成的有机酸进行聚羟基烷酸酯(polyhydroxyalkanoates)合成的摇瓶分批发酵过程. 图5参11
Abstract:
Abstract Conditions of organic acids production during anaerobic acidogenensis of food wastes were investigated. The mass ratio of food wastes to water at 13, pH value of 6.5, and temperature at 30 ℃ were proved to be the most favorable environmental conditions. Maximum total amounts of organic acids could reach around 25~35 g/L during the anaerobic acidogenesis process. Besides, addition of Clostridium butyricum preparation could affect the process of acidogenesis remarkably. Production of polyhydroxyalkanoates by Ralstonia eutropha with organic acids separated from anaerobic digested food wastes as carbon sources in the flask level was also studied. Fig 5, Ref 11
