Ans: The bacteria is grown on Mac Conkey agar so it must be a gram negative bacteria. Gram test results also support the prediction as colonies apear to be pink in colour.
The colonies are lactose non-fermenting bacteria as pink color is not obtained when bacteria is grown on mac conkey agar plate. Example- It could be Salmonella or Pseudomonas species.

The13M is my TSA plate. The one labeled L is my gram stain.
The gram stain is gram negative with rods. I am trying to figure
out what biochemical test to run for my gram negative rod slide to
determine my unknown bacteria.
My test run from- starch plate, MAC, MSA, EMB, SIMS, urea,
phenol red surcrose, simmons citrate, MR/VP.

1. Describe several advantages of differential staining procedures compared with simple staining techniques. 2. Give the purpose of each of the following reagents in a differential staining procedure: a. Primary stain b. Counter stain c. Decolorizing agent d. Mordant 3. Why is it important for the counter stain to be a lighter color than the primary stain? 4. You have done gram staining for a gram positive bacteria, but at the end you observed pinkish-red bacteria under microscope, what was...

How do acid fast stain results compare to gram stain results? a. In other words, what does the following represent? Acid Fast Stain (to Pink bacteria ACO fas广 Blue bacteria C AS Gram Stain Pink bacteria 6eAm- Violet bacteria GRAM f b. Why is there a difference in what the colors mean?
You have three pure cultures of bacteria. One is Gram positive bacteria and the other two are Gram negative bacteria but you have mixed up the labels. You know that one of the Enteric bacteria can ferment glucose and produce ethanol and CO_2. The other can ferment glucose and produce lactic acid. Describe the general procedure you could perform to determine of the three cultures which one is which? A one gram sample of hamburger is diluted to 10^-4 in...
