The results indicated that the strain Jll breaks only the C-SH bond. The optimum temperature and pH of Jll are 20—30℃ and 6.0—8.3 respectively. A systematic identification method—16S rDNA gene sequence comparison, for deodorizing bacteria was carried out. The 16S rDNA gene sequence analysis of strain Jll showed the highest level of 97% homology to Rape rhizosphere.展开更多
