The present invention concerns a new &#x3b2;-galactosidase with transgalactosylating activity isolated fromand a truncated enzyme where the C-terminal end of the &#x3b2;-galactosidase protein has been deleted, resulting in an enzyme with a higher transgalactosylating activity than hydrolase activity. When lactose is used as a substrate, galacto-oligosaccharides are products of the transgalactosylase activity. Galacto-oligosaccharides enhance growth of health-promotingthat may be used in a number of applications in the dairy industry.

[object Object]

A novel L-arabinose isomerase active enzyme and its corresponding gene, derived from a thermophilic source are provided. The enzyme is suitable for the production of D-tagatose, a useful low-calorie sweetener. The enzyme may be obtained from aspecies such as

Thermostable isomerase and use hereof, in particular for producing tagatose

Tagatose is manufactured by hydrolyzing lactose to galactose and glucose and isomerizing galactose to tagatose and chromatographic separation and recycling any unconverted compounds. Thereby high yields of pure tagatose are obtained.
