Synthesis of riboflavin by Ermothecium ashbyii.

Riboflavin production by E. ashbyii employing
wheat and rice bran, malted barley
and ragi, oilseed cakes, tapioca and potato
flour and lucerne meal as substrates has been
investigated. Wheat and rice brans have been
found to be the best substrates for the production
of the Vitamin by the organism. A method
for the preparation of a riboflavin concentrate
employing wheat bran as substrate
is described.
