Abstract
An alpha-amylase enzyme having optimum pH activity under alkaline conditions is produced from Bacillus species NRRL-3881. The enzyme is stable in the presence of chelating agents and is useful in producing maltose-containing products.
Claims1
A process for the production of an alpha-amylase having maximum activity at a pH value from 9 to 9.2 and at about 50.degree. C. comprising growing under aerobic conditions and at a pH from about 8 to about 10 a culture of Bacillus species NRRL B-3881 in a medium containing appropriate nutrients and then recovering the enzyme therefrom.
