Abstract: 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.

Key words: Bacillus cereus; identification; denitrification ability
