Abstract
Maltase is produced by growing a mutant of the yeast strain Saccharomyces italicus capable of growing in a growth medium utilizing sucrose as the carbon source. Maltase production is optimized by controlling time of fermentation, growth medium composition and sonication time during maltase recovery.
Claims8
In a process for forming maltase utilizing Saccharomyces italicus in a growth medium, said Saccharomyces italicus being obtained by mutation of Saccharomyces italicus and having the property of producing maltase while grown on a carbon source selected from the group consisting of maltose, glycerol, acetate, fructose, glucose and sucrose, the improvement which comprises utilizing in the growth medium yeast extract at a concentration of between about 1 and 15 g/L.
