3 Set up a bunsen burner on your ring stand with the ring clamp and a wire gauze over it. 4 Fill the can with tap water until it is about half-full. Place the can on top of the wire gauze on the ring clamp. 5 Turn on the bunsen burner to heat/boil the water. Let steam start to appear before putting the slide on the can. The technique routinely used to stain endospores is the Schaeffer-Fulton Method (Figure 6), which uses the primary stain Malachite Green, a water soluble stain that binds relatively weakly to cellular material, and heat, to allow the stain to break through the cortex of the spore (Figure 7). Procedure. The catalase test can be performed by two standard methods, namely the tube and slide method. Tube Method. It involves the following sequential steps: First, sterilize the test tubes by either using an autoclave or a hot air oven. Then, pour 1-3 ml of hydrogen peroxide into the tubes under sterile conditions..

Endospore staining uses two stains to differentiate endospores from the rest of the cell. The Schaeffer-Fulton method (the most commonly used endospore-staining technique) uses heat to push the primary stain ( malachite green) into the endospore. Washing with water decolorizes the cell, but the endospore retains the green stain. Because the endospore coat is highly resistant to staining, a special method was developed to make them easier to see with a brightfield microscope. This method, called the endospore stain , uses either heat or long exposure time to entice the endospores to take up the primary stain, usually a water soluble dye such as malachite green since ....

The staining procedure of endospore (Fig. 17.8) by Schaeffer-Fulton method is as follows: i. A thin film of young culture (smear) of endosporous bacteria is fixed on a clean slide. ii.

Web. Principle: Endospore staining is a differential staining technique where the spore is stained in a manner so that it can be distinguished from the vegetative part of the cell. Spores are structures remarkably resistant to heat, radiation, chemicals and other agents that are typically lethal to the organism. Staining procedure Cover the streaks with a sheet of absorbent paper. Put the slide atop a staining rack with a heating beaker or water bath. After filling the absorbent paper with malachite green, steam it for three to five minutes. Toss the discoloured absorbent paper in the trash, and give it a couple of minutes to cool. Why is water, rather than alcohol, sufficient for the destaining step in the endospore staining procedure? A) malachite green is not soluble in alcohol B) malachite green has a low affinity for cellular material C) destaining is not important for the success of the procedure D) safranin will not adhere to cells that have been rinsed in alcohol.
