Starch degrading enzymes like amylolytic enzymes are generally significant in the industries to deal with biotechnology, with immense applications in food, textiles, fermentation, and paper. Bacteria produce amylase chemicals including utilizing Bacillus sp., a naturally found polymer, for example, starch, proteins, gelatin
starch degrading microbes in pure culture from soil utilizing a starch loaded agar medium, The two bacterial strains Bacillus amyloliquefaciens and Bacillus licheniformis and cow manure are some of example
Cow manure was used as a source of starch degrading bacteria because it contain amylase.
Amylase is an enzyme that breaks down complex carbohydrates molecules(starch) into smaller molecules, making it possible to absorve those molecules.
Cows have this enzyme in their feces because they don't use it as much.
This will make the microorganisims in the manure use starch as their main food source.
2. Besides this use, Bacteria that degrade starch can be used in food, fermentation, textile and paper industries.
The genus Bacillus are an example of starch degrading bacteria.
3. Starch agar is selective for starch degrading bacteria because it tests the ability of an organism to produce amylase.
In this medium, there is Gram iodine that will react with the starch in the agar to create blue coloration plate.
