[目的]从加入农富康生物菌剂、农保有机肥发酵剂和强兴堆肥发酵剂发酵的猪粪好氧堆肥中,筛选出高效抑制臭气的菌株.[方法]以新鲜猪粪为原料接种发酵剂,通过选择培养基进行分离筛选,筛选出的菌株接种至新鲜猪粪检验其除臭效果.[结果]共筛选出3株可高效抑制臭气的菌株,分别标记为nf5、nb11和qx18.通过形态学和生理生化实验,鉴定该三种菌株:nf5为乳酸杆菌科乳酸杆菌科(Lactobacillaceae),nb11为曲霉科(Aspergillace-ae),qx18为酵母菌科(Saccharomycetaceae).[结论]将三种菌株1 ∶ 1复配优化,使用单因素法可以确定最佳接种条件为:猪粪含水率50%,最佳发酵温度32℃,接种量12%.单菌株中臭气抑制效果最佳...

[Objective]The strains with high efficiency to inhibit odor were screened from the pig manure aerobic compost fermented with Nongfukang biological bacteria agent,Nongbao organic fertilizer starter and Qiangxing compost starter.[Methods]The starter was inoculated with fresh pig manure,and the selection medium was used for separation and screening,and the screened strains were inoculated into fresh pig manure to test the deodorization effect.[Result]A total of 3 strains that can effectively inhibit odor were screened,labeled as nf5,nb11 and qx18,...
