A further study of the use of date extract "dibis" for mycological fat production in still and shaken cultures

Fungal growth and fat formation on date extract “dibis” medium were poor and slow. Addition of corn‐steep liquor (c.s.l.) as a source of nitrogen and other nutritive substances led to a remarkable increase in growth and in fat yield. The fat content in fungal mycelium increased about 4 times. Shaken cultures were superior to still cultures with regard to growth and fat yield only when a high concentration of c.s.l. was added to dibis medium. Under other experimental conditions, still cultures led to heavier mycelium and higher fat contents than shaken cultures.
