*Negative Staining* Procedure - 1. Add a droplet of water 2. Using an aseptic technique, place a loopful of the microorganism from the culture in the droplet and mix 3. Place another slide at a 45° angle in a drop of nigrosin at the edge of the slide with mix 4. Push or pull the slide over the the mix to form thin layer over. Leave to air dry Bacillus (Bacilli pl.) - *Rod* shaped bacteria Because of a snowstorm, your regular laboratory session was canceled and the Gram staining procedure...
