Abstract
A maltase enzyme is prepared by growing a strain of Saccharomyces, ATCC 20 488, on a medium containing maltose or malt extract and has been found to be useful in assays for amylase.
Claims14
Maltase enzyme characterized by hydrolyzing maltotetraose only about 1/100 as fast as maltose and maltopentaose only about 1/500 as fast as maltose and prepared by growing a strain of Saccharomyces, ATCC 20,488, in a growth medium containing at least one of maltose, maltotriose or malt extract derived from a plant source, releasing the enzyme from the yeast cells, and recovering the enzyme.
A process for prepaing a novel maltase enzyme which comprises growing a novel strain of Saccharomyces, ATCC 20 488, in a growth medium which comprises at least one of maltose, maltotriose or malt extract derived from a plant source.
