State Key Laboratory of Heavy Oil Processing , China University of Petroleum , Beijing 102249 , China ; 2 . Department of Chemical Engineering , Beijing Institute of Petrochemical Technology , Beijing 102617 , China) Abstract: Aspergillus f umigatus Fresen . is used in oil desulfurization after the domestication . It can simultaneously metabolize with many complicated organic sulfur compounds ,especially with 4 ,6dimethyl dibenzothiophene . It has a significant influence on lowsulfur content petroleum products ,with which 48 hours’desulfurization rate can be more than 98 % ,and 96 hours’desulfurization rate for 0 # diesel oil can be 9043 %.
