They are almost impossible to destroy! They resist: heat, cold, freezing, drying, radiation, and chemicals. Endospore production is a very important characteristic of some bacteria, allowing them to resist adverse environmental conditions such as desiccation, chemical exposure, extreme heat, radiation, etc. 2018-09-30 Endospore Stain 1. Perform a bacterial smear of Bacillus or the organism you want to stain, as discussed in Figure 3-52 on page 150 of your lab manual. 2. Place a small piece of bibulous paper over the smear.

The endospore staining technique is a differential staining method. This method helps in the detection of endospore-containing bacteria, thus help in the classification of bacterial cells. Some bacterial cells have the ability to convert themselves into endospores in extreme environmental conditions. 2019-07-06 This method, called the endosporestain, 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 endospores are permeable to water. Endospore Staining is a technique used in bacteriology to identify the presence of endospores in a bacterial sample, which can be useful for classifying bacteria.

The counterstain is SAFRANIN. SP+ microbes vegetative cells stain as pink colored rods while internal endospore or released smaller round or egg-shape endosproe stains GREEN. 2018-09-30 · Due to the highly resistant nature of endospores, they are not easily penetrated by stains. Thus, it is necessary to steam the stain into an endospore. The Schaeffer-Fulton method is the most commonly used endospore staining technique, which uses Malachite green as the primary stain.

Therefore, the primary stain has to be forced into the endospore. The use of heat is to enhance the penetration of the primary stain into the endospore. The slide with malachite green can be heated up to 3-5 minutes.
