A microbiologist is attempting to culture bacteria from human feces and chooses to use LB agar, rationalizing that it is a rich medium. What does it mean to be a "rich" medium and what types of microbes does a rich medium select for? When he compares direct microscopic counts of microbial population density to the counts he obtains from cultivating of the colonies on the LB agar plate and incubating them at 25 degrees Celsius, he realizes that he has cultured only a small fraction of the colonic bacteria. Discuss three things wrong with his approach and how you would fix them to maximize recovery of the colonic microbiota.
