Is Sample Capable of Degrading Starch? A yes yes yes B yes yes yes C yes yes yes D yes yes yes Post-Lab Questions 1. Why was cow manure used as a potential source of starch degrading bacteria? The cow manure has a shallow protein content and a very high starch because it has a fibrous diet that dictates a lower need for amylase in the small intestine—the microorganisms in cow manure harvest starch as their primary food source rather than protein. Cow manure is an excellent source of starch degrading bacteria, and making is achievable to mop up those molecules. 2. What are some other potential sources for starch degrading bacteria? Some other potential sources for starch degrading bacteria include food, fermentation, textile, and paper industries.
