Positive or Negative ???

When coming into lab today Courtney and I made a gram stain on each of our bacterias, the unknown and the dollar bill. The unknown turned out to be gram negative. We know this because it did not hold the crystal violet stain and took the safranin. This tells us that it has a thiner cell wall. The dollar bill bacteria had the same results as the unknown, it was also gram negative for the same reasons. The gram stain showed that our bacteria aren't streptobacillis but actually just single bacilli that were together or laying next to each other.
