ABSTRACT:
A thermal stable beta-galactosidase enzyme is produced from new strains of Bacillus stearothermophilus. The beta-galactosidase is suitable for hydrolysis of lactose at temperatures of at least 55.degree. C. and is especially suitable for use at temperatures of at least 65.degree. C. For hydrolysis of lactose, the beta-galactosidase enzyme may be in the form of substantially purified enzyme that has been immobilized or immobilized whole cells containing beta-galactosidase enzyme.
