以猪粪、麦秸、菌糠为堆肥基质，接种复合微生物菌剂，研究了重金属Cu对堆肥过程的影响。Biolog EcoPlate（TM）试验表明，低浓度Cu能提高微生物群落转化利用高分子碳源的能力，加速农业废弃物的分解;高浓度Cu对微生物群落利用复杂大分子碳源的能力有抑制作用，延长农业废弃物的分解。酶活性测试结果表明，低浓度Cu在堆肥前期对酶活性有激活作用，在堆肥后期对酶活性有抑制作用;高浓度Cu在整个堆肥过程中对酶活性有抑制作用。(c)2012爱思唯尔有限公司保留所有权利。
With the compost matrix of pig manure, wheat straw, and spent mushroom substrate, and then inoculated with the Compound Microbe Preparation, the study investigated the effects of the heavy metal Cu on the process of composting. Biolog EcoPlate (TM) test revealed that at a low content, Cu could improve the capacities of microbial communities to transform and exploit carbon sources in the form of polymer, thus speeding up the decomposition of agricultural wastes, and at a high content, Cu presented inhibiting effect on microbial communities to exploit complex macromolecular carbon sources, thus extending the decomposition of agricultural wastes. Enzyme activity testing showed that at a low content, Cu presented enzyme activity-activating effect at the early period of composting and inhibiting effect in the late period of composting, and at a high content, Cu presented enzyme activity-inhibiting effects through the process of composting.
