1. For the production of single-cell protein, isolation of yeast strains from oil-soaked soils and water was carried out. Out of several yeasts isolated, nine were identified and found to belong to the genus of Candida, Trichosporon, Pichia, and Saccharomyces. 2. Strains of Candida and Trichosporon grow well in gas oil with high specific growth rates. 3. Crude protein content of the dried cells vary between 48 and 62%.
