Sources, properties and suitability of new thermostable enzymes in food processing.

Investigations concerning recombinant a-amylases from Pyrococcus woesei and thermostable a-glucosidase from Thermus thermophilus indicate their suitability for starch processing. Furthermore, the study of recombinant ss-galactosidase from Pyrococcus woesei suitable for purpose of low lactose milk and whey production are also presented. The activity of this enzyme in a wide pH range of 4.
