Abstract:
The structure of the cell membrane of Ecemothecium ashbyii is considered to be one of the main obstacles in the improvement of riboflavin productivity, which impedes the release of riboflavin from the cell into the fermentation broth. The results of the present study show that stimulation on growth and riboflavin biosynthesis phase, the content of riboflavin was most obviously enhanced, as compared with the control and the total riboflavin quantity released by ultrasonic treatment. The optimal stimulation time was from 104 to 112 h and ultrasonic should be loaded every 1.5 h.
