- What is the theory about the mechanism of the Gram-stain reaction? please include references/citationwhat is gram stainingBased from the results obtained from Gram staining, explain why bacterial cells retained or changed their color. Briefly explain the principle behind the procedure. Cite advantages of differential staining method (Gram staining and endospore staining) over simple staining only. List other staining methods aside from those you performed in the laboratory. conclusion:
- You are performing a Gram stain on Gram-negative bacteria, and you stop after the addition of the alcohol. What is the appearance of the bacteria at this point? ○ pink ○ colorless ○ blue ○ purpleSubmit screenshots of the Gram stain (1000x total magnification) and Endospore stain (1000x total magnification).start with the results of your Gram Stain. In the spaces labeled appearance& observations, indicate what you see. For instance, "red, long, rod-shaped cells." Under Results indicate the correct term that goes along your observation. For the gram stain, it is sufficient to write the word "positive" or negative in this space.
