STUDIES ON THE INDUSTRIAL PRODUCTION OF RIBOFLAVIN BY THE SUBMERGED CULTURE OF EREMCTHECIUM ASHBYII : (VII) FERMENTATION WITH A 100 LITERS PLANT

Abstract

The following results were obtained by a submerged culture of Eremothecium ashbyii using a fermentor of 100 liters capacity : 1) Riboflavin of 50-100mg% were obtained on a medium containg glucose and peptone as main substrates ; the maximum yield was 109mg%. 2) On a medium consisting of cane molasses and fish meals chiefly, riboflavin yields were 100-150 mg% but the maximum yield was found to be 217mg%.
