In the acid-fast stain, the purpose of the methylene blue is to __________. (1) remove the stain from non acid-fast cells (2) kill bacteria (3) stain non-acid-fast cells (4) disinfect the slide
In the Gram Stain, safranin is the dye used to stain gram negative bacteria. This solution is 0.5%(wt/vol) safranin. How many milligrams of safranin are in a 120 mL safranin solution? Report your answer to two decimal places. Perform all calculations in a single step using Excel to avoid accruing rounding error.

Exercise 8 - Gram Staining Procedure for gram staining. Know all chemicals/reagents used in correct order, function of each chemical, the effect of cach chemical and how gram + and gram - bacteria would appear at each step Color reactions at each step of procedure. Know why, based on the differences in cell wall structure, that the gram + vs gram - bacteria stain either purple or pink. What washes off in the decolorizing step of a gram - bacteria?...
