  • Method for manufacture of .alpha.-galactosidase by microorganism
    Patent number: 3957578
    Abstract: When novel mold strains belonging to genus Absidia are cultured in an inducer-containing medium of the type ordinarily used for the culture of .alpha.-galactosidase producing molds, notably high .alpha.-galactosidase activity is produced and absolutely no invertase activity is produced in the mycelia. By treating beet molasses or beet juice with these mycelia, the yield of sucrose can easily be enhanced, since raffinose which is a substance impeding the crystallization of sucrose is effectively decomposed and sucrose is allowed to remain intact.
