Isolation and characterization of deodorizing bacteria for organic sulfide malodor

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℃ 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. 作 者： JIANG An-xi    LIU Bo    ZHAO Yang-guo    LI Zheng    BAI Yu    CHENG Yang-xue   作者單位： School of Municipal and Environmental Engineering,Harbin Institute of Technology,Harbin 150090,China  期 刊： 環境科學學報（英文版）  ISTICSCI   Journal： JOURNAL OF ENVIRONMENTAL SCIENCES  年，卷(期)： 2004, 16(5)  分類號： X172 X703  Keywords： 16S rDNA gene    methyl mercaptan    Ethanethiol    Rape rhizosphere
