Amylolytic enzymes produced by the yeast Saccharomycopsis fibuligera

Two strains of the food-borne amylolytic yeast Saccharomycopsis fibuligera were selected from a broad spectrum of S. fibuligera strains found in culture collections of microorganisms. These were analysed with respect to production and characterisation of their amylolytic enzymes. S. fibuligera KZ represents a strain synthesizing an amylolytic complex composed of alpha-amylase, glucoamylase and alpha-glucosidase. S. fibuligera IFO 0111 represents a strain producing only one amylolytic enzyme -glucoamylase, with a property unique among yeast amylases, namely the ability to degrade raw starch. Information on molecular-genetic aspects and enzymatic behaviour of amylolytic enzymes produced by both strains is presented.
