A date extract known locally in Iraq as “dibis” was used as substrate for mycological fat formation by Penicillium lilacinum, P. soppii and Aspergillus nidulans. The three fungi were grown on dibis medium at three concentrations. Carbohydrates readily disappeared but this was accompanied by poor fungal growth and low yields of fat. Fungal growth on dibis media enriched with asparagine led to heavy mycelial yields together with higher fat contents. Both economic and fat coefficients rose considerably. It is concluded that nitrogen deficiency in dibis media is at least one of the major factors against good fungal growth and high fat formation.
