Thermostable a-Amylase of Bacillus stearothermophilus
Some general and physical properties and the’ amino acid composition of the thermostable cr-amylase of Bacillus sbarothermophilus have been described in previous papers (l-3). In an effort to further correlate the thermostability of this enzyme with its molecular organization, a study of the structure of this protein has been undertaken. In this paper are reported the results of an investigatio...
متن کاملBacillus stearothermophilus. I. Thermal and pH stability of the amylase.
Investigators are agreed (Kneen and Sandstedt, 1946; Myrback and Neumuiller, 1950) that bacterial amylases, except crystalline preparations (Meyer et al., 1947; Bernfeld, 1951), possess a greater thermostability than other alpha-amylases. Although many investigators have studied the heat stability of amylases from various sources, no study has been published comparing the thermal resistance of ...

Welker, N. E. (Western Reserve University, Cleveland, Ohio) and L. Leon Campbell. Induction of alpha-amylase of Bacillus stearothermophilus by maltodextrins. J. Bacteriol. 86:687-691. 1963.-Technical-grade maltose contained 3.5% glucose, 0.5% maltotriose, and 2.5% of the higher molecular weight maltodextrins. The first five homologues (maltose being the first in the series) of the maltodextrin ...
متن کاملMolecular Engineering of the Geobacillus stearothermophilus α-Amylase and Cel5E from Chlostridium thermocellim; In Silico Approach
Background: Considering natural thermal stability, Geobacillus stearothermophilus amylase and Cel5E from Clostridium thermocellum are good candidates for industrial applications. To be compatible with the industrial applications, this enzyme should be stable in the high temperatures, so any improvement in their thermal stability is valuable.Objectives: Us...
متن کاملCulture Conditions for Production of Thermostable Amylase by Bacillus stearothermophilus.
Bacillus stearothermophilus grew better on complex and semisynthetic medium than on synthetic medium supplemented with amino acids. Amylase production on the complex medium containing beef extract or corn steep liquor was higher than on semisynthetic medium containing peptone (0.4%). The synthetic medium, however, did not provide a good yield of extracellular amylase. Among the carbohydrates wh...
