It is the most common method of endospore staining, which makes the use of three reagents, namely primary stain, decolourizer and counterstain. Since malachite green is water-soluble and does not adhere well to the cell, and since the vegetative cells have been disrupted by heat, the malachite green rinses easily from the vegetative cells, allowing them to readily take up the counterstain. Malachite green 0.5% (this is the primary stain) - It can simply be prepared using 0.5 grams of malachite green with 100 ml of water; Tap/distilled water (decolorizing agent) Safranin (2.5%) - This is the counter stain and can be easily prepared using 2.5 grams of safranin O and 100ml of 95% ethanol; Staining … ... as a treatment for infections in fish (when diluted), and as a bacteriological stain. 125 grams of malachite green powder with 25 milliliters of distilled water, and then vortex the solution until dissolved.
