Production of Microbial Lipids from Beet MolassesS. A. Sabry, K. M. Ghanem, H. H. YusefFrom Department of Botany, Faculty of Science, Alexandria University, Egypt.A variety of yeasts were cultivated on beet molasses (BM)-containing medium. Rhodotorula glutinis was superior to the other yeasts in lipid production (14% on dry weight basis), as well as in the efficient conversion of BM sugars to lipids (7%). Repeatedly centrifuged BM solution offered the best molasses sample which allowed the production of relatively high yeast yields. Maximum lipid yield (24.1%) was achieved with 8 days old cultures of Rhodotorula glutinis grown on a medium composed of (g/L): NH4NO3, 3; NaH2PO4, 0.7; K2SO4, 0.1, ZnSO4.7H2O, 0.05; FeCl3, 0.05; centrifuged BM, 60. pH 7.0.
