Two strains of the food-born 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 a-amylase, glucoamylase and a-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.
Key words: Saccharomycopsis fibuligera, a-amylase, glucoamylase, a-glucosidase, raw starch degradation.
