Without thiamine practically no growth of the fungus took place; omission of pyridoxine had nearly as adverse an effect. Raffinose and cellobiose were the best carbon sources; glucose also gave a good yield of mycelium. Statistical analysis of factorial experiments indicated that a correct balance between the mineral constituents of the medium and between the carbon and nitrogen sources is essential in order to obtain a high yield of mycelium. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-12-3-387
