Purification and Properties of an α-Glucosidase (Glucoamylase) in Sugar Beet Seed

Purification and properties of an amylopullulanase, a glucoamylase, and an alpha-glucosidase in the amylolytic enzyme system of Thermoanaerobacterium thermosaccharolyticum.

Thermoanaerobic bacteria are of considerable interest as producers of thermostable amylolytic enzymes. The soluble amylolytic enzyme system of Thermoanaerobacterium thermosaccharolyticum DSM 571 was fractionated into a pullulanase, a glucoamylase, and an alpha-glucosidase. The enzymes were purified to homogeneity and their physical and catalytic properties were studied. The pullulanase, which c...

Purification and Properties of an Inducible p-Glucosidase of Yeast*

In the past decade considerable advances have been achieved in the study of induced enzyme biosynthesis in microorganisms. A comparison of three of the better studied systems, P-galactosidase in Escherichia coli (l), penicillinase in Bacillus cereus (2), and oc-glucosidase in Xaccharomyces cerevisiae (3) indicates that there are a number of differences in these inductions. In order to compare f...

Effect of Drying Conditions on Properties of Dried Sugar Beet

The Effects of Chemical Purification on the Color of Thin and Thick Juices in Sugar Beet Factories

Background and Objectives: Recognizing the impurities of sugar beet and also comparing different methods of juice purification have shown that the chemical purification based on lime and carbon dioxide is really efficient and economic in the sugar industry. Factories have to control and improve purification stages to achieve clear juice with high chemical purity, low color, minimum hardness, su...
