从活性堆肥(50-70摄氏度)和可能完成的(常温)堆肥中分离和鉴定了显著的细菌菌株，并使用碳利用技术与用于细菌鉴定的计算机数据库匹配进行鉴定。主要细菌包括大肠杆菌、沙雷氏菌。粘质假单胞菌、弗氏柠檬酸杆菌、肺炎克雷伯菌、鸡肠球菌、肠杆菌、阴沟肠杆菌、绿脓杆菌、产碱假单胞菌、产碱假单胞菌、放线杆菌基因种和粪产碱杆菌。当采样温度超过60摄氏度时，发现的突出细菌被认为是在这个温度或更高的温度下生长的，尽管它们被归类为嗜中性菌。从活性堆肥中分离出的这些菌株强烈表明，一些中温菌在高温下具有生存和复制的机制，这意味着在堆肥过程中发挥了作用。
The prominent bacterial strains from both active (50-70 degrees C) and presumably completed (ambient temperature) composts were isolated and identified using a carbon utilization technique with computerized database matching for bacterial identification. Prominent bacteria included Escherichia coli, Serratia. marcesens, Citrobacter freundii, Klebsiella pneumoniae, Enterococcus gallarium, Enterobacter, cloacae, Pseudomonas aeuginosa, Pseudomonas pseudoalcaligenes, Pseudomonas alcaligenes, Actineobacter genospecies and Alcaligenes fecalis ss fecalis. When temperatures at sampling exceeded 60 degrees C, the prominent bacteria found were assumed to be growing at or above this temperature, despite their classification as mesophils. The isolation of these strains from active compost strongly indicates that some mesophils have mechanisms for survival and perhaps replication at elevated temperatures, implicating a role in the composting process.
