摘要：

A thermostable beta -glucosidase from Thermus sp. Z-1 that not only hydrolyzes beta -glucosides but also beta -galactosides was shown to efficiently produce oligosaccharides during hydrolysis of lactose. The yield of oligosaccharides was more than 40% for 0.88 ni lactose solution at 70 degreesC at pH 7.0. The major product was a trisaccharide, 3 ' -galactosyllactose, formed by a galactosyltransfer reaction.
