Abstract
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.
