An investigation was carried out on the carbon and nitrogen sources needed for the growth of a yeast, Candida valida (syn. Candida mycoderma), isolated from Ogi, a fermented edible corn product given to babies at weaning. The suitability of this organism as a protein supplement in foods was also determined. The yeast was grown in different carbon sources: glucose, fructose, lactose, maltose, starch, dextrin, mannitol and ethanol, and in different nitrogen sources like urea, amino acids, ammonium nitrate, sodium nitrate and ammonium sulfate, as part of the synthetic basal medium for 7 days and the growth measured using the dry weight method. A significantly high increase in yield was observed when 1% fructose was used and maximum yield was obtained with 3.5 and 0.2% (w/v) of fructose and urea as carbon and nitrogen sources, respectively. Growing the fungus in 0.3% cane molasses, a natural substrate gave a significantly higher increase in yield than in a synthetic medium. As a food supplement, other nutrient contents of this organism such as ash, crude fiber, lipids and carbohydrates were also analyzed in addition to the protein, free amino acids and energy values
