A strain of hydrocarbon degrading yeast named YH-41 was isolated and purified from the soil polluted by crude oil from Shengli oil field, China. The strain was identified by morphological, biochemical characteristics and 18S rDNA sequence analysis, the results show that the strain was similar to the haploid nucleus of Pichia ohmen, which belong to Candida., The GC analysis showed that the yeasts degradated diesel oil. Through bioremediation experiments, we can study the feasibility of

The degradation rate of residual oil in the same period of time increased about 20% compared with other treatment without adding the yeasts.
