Abstract Throughout the experimental process, we performed a series of steps which consisted of our gram staining technique. When performing this technique, we basically gathered our materials and recorded our procedures step by step. Afterwards, we then proceeded staining the three different staining dyes with the two specific specimens we had. These two specimens were B. subtilis and E. coli K-12 (nutrient broth) and we manipulated methylene blue, safranin, and crystal violet staining dyes for the experiment. Upon staining, we observed the various shapes, cell morphologies, and sizes of each specimen. They all appeared to have had a distinctive color and image. Thus, we were able to determine which one was gram-negative and positive based on our results. Above all, this gram staining technique helped to be able to distinguish between gram-positive and gram-negative cells.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
