EXXON PRT TIME SULFUR K EDGE SPECT IN SITU PROBE OF SULFUR SPECIES IN BACTERIA

微生物脱硫提供了一种潜在的新方法， 以最小的环境污染从燃料油中除去硫化合物 影响（Gray等人，（1996）Nature Biotechnology 14，1705-1709）。 在分离个体的基因方面已经取得了进展 酶在脱硫途径，并研究其功能， 重组大肠杆菌 我们正在使用硫K边光谱， 通过这些生物对燃料油进行脱硫， 试图了解它们在复杂混合物中的底物特异性。

Microbial desulfurization offers a potential new approach to removing sulfur compounds from fuel oils with minimal environmental impacts (Gray et al., (1996) Nature Biotechnology 14, 1705-1709). Progress has been made in isolating the genes for the individual enzymes in the desulfurization pathway, and studying their function in recombinant E. coli. We are using sulfur K-edge spectroscopy to follow the desulfurization of fuel oils by these organisms in an attempt to understand their substrate specificity in complex mixtures.
