OPTIMIZATION OF ALKALINE Α-AMYLASE PRODUCTION BY THERMOPHILIC .

Background: Starch-degrading amylase enzyme is important in biotechnological applications as food, fermentation, textile, paper and pharmaceutical purposes. The aim of current study to isolate alkaline thermostable α-amylase bacteria and then study the composition of medium and culture conditions to optimize cells growth and a-amylase production.

Materials And Methods: Thermophilic amylase producing bacterium was isolated from local hot water-springs in Gazan city Saudi Arabia.
