title: [Treatment of drilling wastewater from oil field by using yeast].
abstract: Two strains of yeast, namely Wickerhamiella domercqii and Candida boidinii, were acquired through screening from soil samples contaminated by drilling wastewater. A TOC removal of 40.5% was acquired when the mixture of the two yeast strains was used for drilling wastewater treatment, a little higher than that with activated sludge acclimated with wastewater (35.2%). Some organic compounds in the fraction of molecular weight above 60,000 were found to be biodegradable.
