ABSTRACT
The microbial degradation oforganic sulfur compounds was examined
in aerobic conditions employing a pure culture of a Pseudomonas sp.,
isolated from the soil. The effect of n-alkanes on the degradation of
dibenzothiophene (DBT) showed” that the assimilation of the sulfUr
compound by the microorganism is favoured by n-dodecane. Moreover,
the saturated fraction was seen to enhance the degradation of sulfUr
compounds to be found in a deasphaltenated heavy oil.
