Answer:
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
Klinglers iron agar medium is used to find the enterobacteria which can ferment glucose , lactose and hydrogen Sulphide . They are H₂S producing bacteria .
This media have phenol red as an indicator. When the glucose is fermented to acid , the production of acid turn the indicator from red to yellow, but it is then reoxidised and turns red again . When lactose is fermented it produce large amount of acid , and turn indicator yellow . Hence the slant will become yellow.And combination of ferrous sulphate and sodium thiosulphate helps in detection of H₂S which produce black color at the butt .
