Studies on the production of alkaline α-amylase from Bacillus subtilis CB-18.
BACKGROUND Amylases are among the main enzymes used in food and other industries. They hydrolyse starch molecules into polymers composing glucose units. Amylases have potential applications in a number of industrial processes including foods and pharmaceutical industries. Alkaline α-amylase has the potential of hydrolysing starch under alkaline pH and is useful in the starch and textile industr...
متن کاملBottleneck in secretion of α-amylase in Bacillus subtilis
Amylase plays an important role in biotechnology industries, and Gram-positive bacterium Bacillus subtilis is a major host to produce heterogeneous α-amylases. However, the secretion stress limits the high yield of α-amylase in B. subtilis although huge efforts have been made to address this secretion bottleneck. In this question-oriented review, every effort is made to answer the following que...
متن کاملHeterologous expression, biochemical characterization, and overproduction of alkaline α-amylase from Bacillus alcalophilus in Bacillus subtilis
BACKGROUND Alkaline α-amylases have potential applications for hydrolyzing starch under high pH conditions in the starch and textile industries and as ingredients in detergents for automatic dishwashers and laundries. While the alkaline α-amylase gains increased industrial interest, the yield of alkaline α-amylases from wild-type microbes is low, and the combination of genetic engineering and p...
متن کاملProduction, purifi cation, and characterization of α-amylase by Bacillus subtilis and its mutant derivates
Th e eff ects of various carbon and nitrogen sources on production of α-amylase by Bacillus subtilis and its mutant derivates were investigated. Th e maximum production of α-amylase by all strains was obtained in the presence of mesoinositol as the carbon source. Th ere was no more signifi cant increase in enzyme yield in the case of the supplementation of nitrogen sources, whereas malt extract...
متن کاملThe Theoretical Study on a Nano Biosystem Consisting of Nano Tube-Catalytic Site of Bacillus Subtilis α-Amylase, PDB: 1UA7
α-Amylase has been studied extensively from various sides. This enzyme is used in many industries .Many applications of this enzyme have encouraged us for greater attempts on the study of α-amylase and to search for more effective processes. In this investigation, the structure of nanotube - catalytic site of bacillus subtilis α- amylase was optimized by hype...
