Read about bacterial amylase l and its animal feed, food, beverage & ingredient applications call bio-cat at 877-912-4622 for more info jenn worked for over 10 years at yves delorme in charlottesville where she started in production, was promoted to customer service and finally to the it department jenn studied sports medicine at the. The pancreas and salivary gland make amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy plants and some bacteria also produce amylase.

The objective of this work was to study the pattern and the comparison of α-amylase production by using two strains of bacillus licheniformis, mtcc 2617 and mtcc 2618 using four different substrates several authors have reported that the majority of the bacterial amylases have an optimum temperature in range of 30–100 o c. The present review was focused on bacterial amylase and this review assesses the following chapters: amylase, microorganisms and amylases, physiology of amylases, fermentation studies on bacterial amylase production and commercial application of amylases key words: enzyme, amylase, bacteria, physiology, fermentation and applications 1.
The present study deals with the production and comparative study of production of α-amylase from two strains of bacillus licheniformis, mtcc 2617 and 2618, by using four different substrates, starch, rice, wheat and ragi powder as carbon source by submerged fermentation the effect of varying ph and incubation temperature, activator, inhibitor, and substrate concentration was investigated on the activity of α-amylase produced by mtcc strain 2618. Maximum α-amylase production of a-amylase by alteromonas haloplanktis was found at an optimal temperature of 4°c 332 ph optimum ph is a critical factor for the stability of enzyme produced. Bacterial strain was isolated from soil receiving kitchen wastes where conditions for growing were controlled, the bacteria isolated showed that belong to the genus bacillus the strain grows well at 37 o c.
Bacterial amylase: a review article (pdf available) physiology of amylases, fermentation studies on bacterial amylase production and commercial application of amylases.
Generally, production of this enzyme has been carried out by submerged fermentation among the bacterial sources bacillus subtilis, bacillus staerothermophilus, bacillus amyloliquefaciens, bacillus licheniformis, bacillus acidocaldarius, bifidobacterium bifidum and bifidobacterium acerans are important species.
The production of α-amylase by ssf is limited to the genus bacillus, and b subtilis, b polymyxia, bmesentericus, b vulgarus, b megaterium and blicheniformis have been used for α-amylase production in ssf. Bacterial alpha amylase is obtained from bacilus subtilis being an endoamylase it randomly hydrolyses alpha (1,4) glucosidic linkages of amylose and amylopectin of gelatinized starch to produce dextrins of various chain lengths and oligo saccharides.
