Again on September 13th we waited in line to get to the incubator, talking about what happened last time and seeing what our classmates are pulling out. Our spirits picked up after we saw our streak plate. That one little colony spread to cover almost the whole plate. Now we were able to check the colony characteristics and look at our plate under a microscope. This was the day we also got our unknowns. Hannah and I were given Sample B and all we knew about it was that everything made from it had to be placed in the 30 degree incubator. From our sample tube we streaked two slants. We also learned how to stain bacteria with a simple stain technique. Hannah and I were excited to use our dish full of bacteria from the dollar bill. It showed diplococci or small circles in pairs of two. Needless to say, we were pretty pumped for this lab.
