Partial characterization and optimization of production of extracellular alpha-amylase from Bacillus subtilis isolated from culturable cow dung microflora.
Studies of alpha-amylase production by Bacillus subtilis (CM3) isolated earlier from cow dung microflora, were carried out. The optimum temperature, pH and incubation period for amylase production were 50-70 degrees C, 5.0-9.0 and 36 h, respectively. Enzyme secretion was very similar in the presence of any of the carbon sources tested (soluble starch, potato starch, cassava starch, wheat flour,...
متن کاملMolecular Diagnosis and Characterization of Bacillus subtilis Isolated from Burn Wound in Iran
Background: Bacillus subtilis refers to stretched and sometimes curved, gram-positive, aerobic, and catalase-positive bacilli, which has thermo-resistant endospores. It has been known as a normal flora in the human but can be pathogens In the case of opportunistic. Also, it can be the pathogen of nosocomial infections such as wound among hospitalized patients. Purpose of this study was to ident...
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 کاملOPTIMIZATION OF ALPHA AMYLASE PRODUCTION FROM RICE STRAW USING SOLID-STATE FERMENTATION OF Bacillus subtilis
The current study optimized the production of α-amylase by Bacillus subtilis using solid state fermentation (SSF) process. The agricultural by-product of rice straw was utilized as a substrate support for the fermentation process. The characterization of untreated and NaOH-treated rice straw was conducted using Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Analysis (EDX). The o...

Alpha-amylase E.C.3.2.1.1. (1,4 glucan, 4 glucanohydrolase) can be obtained from salivary glands, pancreas and microorganisms such as Pseudomonas and Asperigllus, as well as muscles and ovarian tubes.1.2 Alpha-amylase from Bacillus Subtilis #1024(A TCC 465)* was purified with a highest degree of purity in our laboratory (31.59 U/mg). The extracellular alpha-amylase was subjected to differe...
