A pure culture of an unknown bacterium was streaked onto plates of a variety of media. You notice that the colony morphology is strikingly different on plates of minimal media with glucose compared to that seen on trypticase soy agar plates. How can you explain these differences in colony morphology?
Added by Leah T.
Step 1
The first thing to consider is the composition of the two different media. Trypticase soy agar is a complex medium that contains a variety of nutrients, including proteins, carbohydrates, and salts. This allows a wide range of bacteria to grow, as they can find Show more…

How can you tell that the bacteria growing on a pour plate were different types of bacteria or a contaminant? Check all that apply. A: different colony morphology B: you really can't tell if there are different types of bacteria or if they are the same C: different colors of colonies D: different colors of agar on the plates E: the agar affects the growth of the colonies since they are embedded in the agar F: different sized colonies

In a nutrient medium that lacks histidine, a thin layer of agar containing $^{-} 10^{9}$ Salmonella typhimurium histidine auxotrophs (mutant cells that require histidine to survive) produces $^{-1} 13$ colonies over a two-day incubation period at $37^{\circ} \mathrm{C}$ (see Fig. $25-20$ ). How do these colonies arise in the absence of histidine? The experiment is repeated in the presence of $0.4 \mu \mathrm{g}$ of 2 -aminoanthracene. The number of colonies produced over two days exceeds 10,000 . What does this indicate about 2 -aminoanthracene? What can you surmise about its carcinogenicity?
