Vitamin B1, Vitamin B6 and Biotin as Growth Substances for some Ascomycetes


IN continuation of earlier published investigations1 on the significance of vitamin B1 (aneurin, thiamin) and biotin (vitamin H) for the growth of different fungi, the need for growth substances of a number of Ascomycetes has been more closely studied.
