Fig. 4From: Glutamic acid promotes monacolin K production and monacolin K biosynthetic gene cluster expression in Monascus Morphology (A) of Monascus M1 in different culture medium with different magnifications factor, 2000× , 3000× and 5000× , respectively. M1 was cultured in original medium (A–C), glutamic medium (D–F) for 11 days at 25 °C with shaking at 150 rpm. Spore (arrows #1), Bulges (arrows #2) and Folds (arrows #3) were visibleBack to article page
