Aspergillus terreus was used for riboflavin (vitamin B2) production in a medium containing beet molasses as the sole carbon source. Growth and the vitamin production of the fungus were markedly affected by the composition of the culture medium. A maximum riboflavin yield was achieved at the late exponential growth phase (16 day-old cultures) in the presence of (g/l): centrifuged beet-molasses, 90; L-asparagine, 1; MgSO4.7H2O, 0.5; K2HPO4/kH2PO4 (1:1), 5; and the medium initially adjusted to pH 8.
土曲霉被用于在以甜菜糖蜜作为唯一碳源的培养基中生产核黄素（维生素B2）。培养基的组成显著影响该真菌的生长和维生素产量。在（克/升）以下成分存在的情况下，于指数生长后期（培养16天的培养物）实现了最大核黄素产量：离心后的甜菜糖蜜90；L-天冬酰胺1；七水硫酸镁0.5；磷酸氢二钾/磷酸二氢钾（1:1）5；并且培养基初始pH值调至8。
