Abstract: Strain Jll screened out from different odor origins can efficiently degrade methyl mercaptan and ethanethiol whereas has no ability to remove dimethyl sulfide. The results indicated that the strain Jll breaks only the C-SH bond. The optimum temperature and pH of Jll are 20–30°C 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.

Keywords: 16S rDNA gene, methyl mercaptan, Ethanethiol, Rape rhizosphere
