The Standard Endospore Stain, Atlas pg. 41-42 The standard endospore stain is a vigorous staining procedure using Malachite (mal’ – К – kit’) Green as the main stain and Safranin as a counter stain (other counter stains may be used but we will ignore them for simplicity). Endospores are a bacterial structure for survival that do not readily allow stains to get in or attach to the spore. Spore staining without the use of steam may be performed as follows (watch Microbiology Video: Preparing an Endospore Stain to familiarize yourself with the technique): Preparing an Endospore Stain Prepare2. air-dried bacterial smears as usual but heat-fix the slides by passing them through the Bunsen flame about 20 times. 3.
Essentially, endospore stain is a differential stain. As such, it allows for the differentiation of structures and thus the characterization of a cell based on its physical and chemical nature. In this case, endospore stain as a differential staining technique is largely used for the purposes of distinguishing between vegetative cells and

LAB 7: ENDOSPORE STAIN AND BACTERIAL MOTILITY . A. ENDOSPORE STAIN . DISCUSSION. A few genera of bacteria, such as Bacillus, Clostridium and Clostridioides have the ability to produce resistant survival forms termed endospores.Unlike the reproductive spores of fungi and plants, these endospores are resistant to heat, drying, radiation, and various chemical disinfectants (see Labs 19 and 20)

Endospore Stain . The endospore stain is a differential stain used to visualize bacterial endospores. Endospores are formed by a few genera of bacteria, such as Bacillus . By forming spores, bacteria can survive in hostile conditions. Spores are resistant to heat, dessication, chemicals, and radiation.

Abstract Endospore production is a very important characteristic of some bacteria, allowing them to resist adverse environmental conditions such as desiccation, chemical exposure, extreme heat, rad
Endospore Stain Procedure. Endospore stains require heat to drive the stain into the cells. For a endospore stain to be successful, the temperature of the stain must be near boiling and the stain cannot dry out. Most failed endospore stains occur because the stain was allowed to completely evaporate during the procedure.

Acid-fastness is a physical property of certain bacterial and eukaryotic cells, as well as some sub-cellular structures, specifically their resistance to decolorization by acids during laboratory staining procedures. Once stained as part of a sample, these organisms can resist the acid and/or ethanol-based decolorization procedures common in many staining protocols, hence the name acid-fast. The mechanisms of acid-fastness vary by species, although the most well-known example is in the genus Myc
