The effect of some conditions on the production of single cell oil and provitamin D2 of the yeast rhodotorula glutinis grown on suger cane molasses medium.

Rhodotorula glutinis 12% . filipin 75 / D2 .This study was conducted to show the effect of some cultural conditions on the growth and production of single cell oil (SCO) from Rhodotorula glutinis. The yeast was grown on sugar cane molasses medium having a sugar concentration of 12%. The results have shown that the highest production rate was achieved during the fourth day of incubation and the urea was the best among the nitrogen resources used to stimulate the growth and (SCO) production while the medium contain sodium nitrate and peptone had a suppression effect on single cell oil (SCO) production. The effect of different concentrations of antifungal filipin revealed that filipin at the concentration of 75 mg/l gave the highest growth and provitamin D2 production.
