How much solid agarose and how much water would you use to make 100 ml of a 1.5 % agarose solution? At what point in the Gram Stain procedure would one be able to differentiate Gram-Positive and Gram-Negative cells?...
Gram-positive bacteria are bacteria with thick cell walls. In a Gram stain test, these organisms yield a positive result. The test, which involves a chemical
