1微生物脱有机硫的催化剂制备和条件显示文摘从石油污染土壤中筛选到的一株能专一性降解二苯并噻吩(dibenzothiophene,DBT)生成2-羟基联苯(2-hydfoxybiphenyl,2-HBP)的红球属(Rhodococcus)菌株lawq出发,研究了影响该菌株生长和脱硫的因素.2-HBP对菌体生长、降解DBT酶系的产生及脱硫活力都有抑制作用.研究了生长反应系统中硫酸盐和DBT同时存在条件下,硫酸盐的存在对产生降解DBT酶系的影响作用.对休止细胞脱有机硫反应体系进行了研究,并确定了最佳细胞浓度和反应条件.研究结果表明红球菌lawq具有对硫酸盐不敏感的特点,较适合于生物脱有机硫工艺.许平 马翠卿 李福利 曾义勇 王书宁 宋波 佟明友 H.D.Blankespoor 2002科学通报2002,47,4:11
2脱硫微生物生产和燃油脱有机硫显示文摘利用计算机控制的发酵缸,对脱硫微生物的生产条件进行了初步的探讨,分别进行了pH条件,碳源的选择、最适碳源浓度、氮源浓度和硫源浓度的确定等研究,采用pH恒定、流加碳源工艺可大大提高菌体生产浓度,利用具有专一性脱硫活力的微生物休止细胞和细胞理裂解液,处理加氢精制柴油(来自抚顺石油研究院,硫含量对206μg/mL左右),用于脱硫的微生物包括lawq,IG,X7B,ZT,ZCR,5和6号菌混合液,燃油的实际有机硫脱除率分别为10.6%-90.3%。许平 李福利 俞坚 马翠卿 钟建江 曲音波 H.D.Blankespoor 2001科学通报2001,46,18:9
3Preparation of microbial desulfurization catalysts显示文摘A Rhodococcus sp. lawq, a bacterium isolated from the soil cleaving the C-S bond of dibenzothiophene (DBT) via specific pathway, was investigated for cell growth and for its role in desulfurization. Clearly, the end product, 2-hydroxybiphenyl, inhibited the growth of the strain, the synthesis of the desulfurization enzymes, and the activity of the enzymes. The effects of sulfate on the DBT degradation enzymes were examined in the Rhodococcus sp. lawq growth system with DBT; the sulfate served, concurrently, as the sulfur source. The condition of the resting cells that were used in desulfurization, was also studied. The optimal concentration of the resting cells and the reaction conditions were determined. It was documented that there is no difference between desulfurization activity for resting cells cultured with sulfate as the sole sulfur source and that with the mixture of DBT and sulfate as the sulfur source.XU Ping MA Cuiqing LI Fuli TONG Mingyou ZENG Yiyong WANG Shuning H.D.Blankespoor 2002Chinese Science Bulletin2002,47,13:4
