Initially when unknown microbe #7 was gram stained and observed under the microscope, the color appeared more pink than purple, leading to the conclusion that unknown microbe #7 was gram negative. However, when completing the KOH lysis test, the microbe didn’t become sticky and remained tacky which is how a gram positive KOH test would result. It was decided to double check the KOH lysis test and the second test still yielded the same results as the first, gram positive. The conclusion of unknown microbe #7 being gram negative from the gram stain was an error. This could have been because of the amount of dye on the gram stain, or timing with how long the flooding of the slide should have been done, or human error. But because the KOH lysis test is more reliable than observation of a gram stain under the microscope, it was decided to change the consensus of unknown microbe #7 being gram negative to it being gram
