In a bid to identify suitable microbial indicators of compost stability, the process evolution during windrow composting of poultry manure (PM), green waste (GW) and biowaste was studied. Treatments were monitored with regard to abiotic factors, respiration activity (determined using the SOUR test) and functional microflora. The composting process went through typical changes in temperature, moisture content and microbial properties, despite the inherent feedstock differences. Nitrobacter and pathogen indicators varied as a monotonous function of processing time. Some microbial groups have shown a potential to serve as fingerprints of the different process stages, but still they should be examined in context with respirometric tests and abiotic parameters. Respiration activity reflected well the process stage, verifying the value of respirometric tests to access compost stability. SOUR values below 1 mg O(2)/g VS/h were achieved for the PM and the GW compost.
为了确定堆肥稳定性的合适微生物指标，研究了家禽粪便（PM）、绿色废物（GW）和生物废物条垛式堆肥过程中的演变。对处理过程中的非生物因素、呼吸活性（使用底物利用速率试验测定）和功能微生物群落进行了监测。尽管原料存在固有差异，但堆肥过程在温度、水分含量和微生物特性方面经历了典型变化。硝化细菌和病原体指标随处理时间呈单调变化。一些微生物群落显示出作为不同过程阶段指纹的潜力，但仍应结合呼吸测定试验和非生物参数进行研究。呼吸活性很好地反映了过程阶段，验证了呼吸测定试验评估堆肥稳定性的价值。PM和GW堆肥的底物利用速率值低于1毫克O(2)/克挥发性固体/小时。
