    摘要: A .beta.-galactosidase having a high thermostability is produced by Thermus sp. FERM BP-1678, FERM BP-1679, and FERM BP-1680. The .beta.-galactosidase has an optimum temperature of 75 to 85 degrees celsius, and an optimum pH of 4.5 to 6.5 and an enzymatic activity which is not lowered substantially by 50 mM each of galactose and glucose. The .beta.-galactosidase is used to hydrolyze lactose in foods, such as milk, at a high temperature at which the putrefaction by saprophytes is difficult.

    摘要: Biologically pure strains of Thermus sp. FERM BP-1678, FERM BP-1679 and FERM BP-1680 have been isolated, and are capable of producing a beta-galactosidase. The beta-galactosidase produced by these strains has specific characteristics wherein the enzyme is optimum at a temperature of 75 to 85 degrees celsius and pH of 4.5 to 6.5. Further, the enzymatic activity is reduced by at most 10% in the presence of 50 millimoles (mM) of galactose and glucose, respectively.
