摘　　要：从有关环境中驯化、筛选高效脱臭、快速降解的粪便堆肥优势菌群 ,为粪便堆肥菌剂研究提供菌株 .经在堆肥过程中采样分析 ,得到随堆肥时间延长 ,细菌逐渐减少 ,放线菌逐渐增多 ,霉菌和酵母菌在堆肥的末期显著减少的结论 .在粪便模拟堆肥的不同阶段 ,共分离出 15 6株菌种 ,从脱臭效果、生物活性 (耗氧速率 )、有机物降解率 (CODcr去除率 )等三方面筛选得到 7株能快速脱臭。The microbe in night soil compost during the composting by culture dish counter is primarily analyzed ,especially the bacteria,actinomycetes,molds and yeast. It is found that the bacteria reduced while the actinomycetes increased during 5 day composting,the molds and yeast maintained the same quantity at the first 4 days and educed rapidly at the ultimate day.At the same time of enrichment and redamamation, 156 strain microbe is gained and among them 7 strain microbe is studied from the indicatrixes of deodorization, oxygen consuming speed and COD cr remove proportion.
