Fourth Week

I got the results for my inoculations and saw how the unknown was grown. I included some of the pictures dawn below. But my lab work for this week was Gram Stain. In this method I learned how to identify the type of bacteria, but I still don’t know what exactly my bacteria is. First time when I Gram stained, it all got washed off because I hadn’t heat-fixed the bacteria smear on the slide. Second time, I successfully finished the experiment and got to look at my unknown by microscope. It was purple, so I figured out that it’s Gram Positive, and from the circular shape that it had I found out it was Cocci. Then I could cell morphology by looking at my bacteria’s colony from my isolated bacteria and could see that it was circular, raised, entire type of colony. I also included a picture of my bacteria. Now, I’m looking forward to my next week experiment which is Gram + Catalase Test.
