摘　　要：用感官法初筛选出18株细菌,再通过定性复筛试验,最后从鸡粪中分离出1株具有明显脱氨除臭作用的细菌JNX-8;经菌落形态特征观察、生化试验、16SrDNA测序等过程,鉴定为蜡状芽孢杆菌(Bacillus cereus)。对该菌脱氮性能进行了研究,确定其对硝基氮和氨氮的去除率分别达到51.71%和66.28%。结果显示,菌株JNX-8在鸡粪发酵除臭中具有良好的应用前景。18 bacteria strains were isolated through sensory screening test,then through qualitative rescreening test,JNX-8 strain was isolated from poultry litter because of the best denitrification and deodorization ability.Based on morphology and physiology of colony and 16S rDNA sequence analysis,the strain was characterized as Bacillus cereus.The denitrification ability of JNX-8 strain was studied,51.71% of NO3——N and 66.28% of NH4＋-N were respectively removed by JNX-8.Therefore,JNX-8 had good application prospects in the denitrification and deodorization of poultry litter.
