    This study was made in order to test the enzymes which are produced by young mycelia of Aspergillus Oryzae. It was found that there were 13 kinds of enzymes, i. e., β-h-fructosidase (saccharase), α-d-glucosidase (maltase), β-d-galactosidase (lactase), β-d-glucosidase (emulsin), α-amylase, β-amylase, papain type protease, peptide decomposing enzyme, lab, urease, peroxidase, indophenolase and catalase.
    Among these, peroxidese and indophenolase were weak.
    A report will probably be made later of enzymes other than those noted above.

    1. A method for separation and concentration from liver extract of the growth-promoting factor (or factors) distinct from flavin is given.
    2. The factor (or factors) is readily soluble in ethyl alcohol, andthe addition of a large volume of acetone to the aqueous solution cannot precipitate the active factor. The factor is not precipitated by phosphotungstic acid, but partially by barium. It is not adsorbed by acid clay or charcoal at pH 1.4 and 2.5.
    3. Normal growth is induced in rats when both flavin and liver growth factor are added to the basal ration.
    4. Nicotinic acid cannot replace the active factor, as tested on growth of rats.
    5. Comparison of the properties of the factor indicates that it is distinct from riboflavin, but may perhaps be identical with factor W described byFrost and Elvehjem.
