The Nutritive Value of Fungi

II. The Vitamin B, G and B₄ Content of the Mycelium of Aspergillus Sydowi¹

Four Figures

Department of Agricultural Chemistry and Agricultural Bacteriology, University of Wisconsin, Madison

The addition of 10 per cent of the mycelium of A. sydowi to a ration low in vitamin B (complex) furnished enough of the vitamin to support good growth in rats. Better growth and performance was secured on 20 per cent of the mold.

The mold contained enough vitamin B(B₁) to protect chicks against polyneuritis when it was fed at a 10 per cent level.

Symptoms of pellagra were prevented in chicks on a ration low in vitamin G by the addition of 1 per cent of mold. To secure good growth of chicks it was necessary to add 3 per cent of mold.

Mold added at a level of 30 per cent to a ration deficient in vitamin B₄ completely prevented the onset of paralysis.

This work was supported in part by a grant from the Wisconsin Alumni Research Foundation.
