On the basis of the above data, lit the media in order (from best toworst) according to their ability to support the growth of bacteria. 2. List the three bacterialspeciesinorder of their increasing fastidiousness. 3. Why did the most fastidious organismgrow poorly in the chemically defined Lab Re Synthetic Broth

Solution

The media most able to support bacterial growth in decreasing order are:

Yeast extract broth, nutrient broth, inorganic synthetic broth, glucose broth.

The bacteria in increasing order of fastidiousness are:

E. coli, A. faecalis, S. mitis

The most fastidious bacteria grew the slowest as it has a complex nutritional requirement, and as the chemically defined broth has the least variety of nutrients, a fastidious bacteria will take time to digest the few compounds and make the molecules necessary for survival.
