    What are the types of stains?

    Based on chemical nature: There are three kinds of stain, acidic, basic and neutral, depending upon the chemical nature of the stain. Based on the staining method: There are four kinds of stain, viz. direct, indirect, differential and selective stains.

    • Is water based or oil-based stain better?

      If the wood is going to be in direct exposure to wind, rain, and sunlight, an oil-based stain is the best choice. This is because it is more durable than a water-base and will provide a more complete protective layer against these elements.

      Is there a difference between wood stain and wood finish?

      The Difference Between Wood Stains & Wood Finishes

      Wood stains are meant for adding color, whereas wood finishes are meant to protect the wood. There are a variety of stains and finishes, and many of them consist of different ingredients and are based on different chemical compounds.

      What is stain and types of stain?

      Stain – Majority of the stains used for staining bacteria are of the basic type as nucleic acid of bacterial cells attract the positive ions, e.g. methylene blue, crystal violet. Acidic stains are used for background staining. Mordant – It is a chemical that forms an insoluble complex with.

      What are the two varieties of staining?


      Sr. No. Staining Technique
      1. Simple (Monochrome)
      2. Negative (Relief)
      3 Gram
      4 Acid fast (Ziehl-Neelsen technique)

      What is a primary stain?

      The primary stain (crystal violet) binds to peptidoglycan, coloring cells purple. Both gram-positive and gram-negative cells have peptidoglycan in their cell walls, so initially, all bacteria stain violet. Gram’s iodine (iodine and potassium iodide) is applied as a mordant or fixative.

      What is a secondary stain?

      First cells are stained with crystal violet, followed by the addition of a setting agent for the stain (iodine). Then alcohol is applied, which selectively removes the stain from only the Gram negative cells. Finally, a secondary stain, safranin, is added, which counterstains the decolorized cells pink.

      What is the difference between simple and differential stain?

      A simple stain will generally make all of the organisms in a sample appear to be the same color, even if the sample contains more than one type of organism. In contrast, differential staining distinguishes organisms based on their interactions with multiple stains.

      What does an Endospore stain tell you?

      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.

      What is Fimbriae microbiology?

      Fimbriae are long filamentous polymeric protein structures located at the surface of bacterial cells. They enable the bacteria to bind to specific receptor structures and thereby to colonise specific surfaces.

      What does malachite green stain?

      When more favorable conditions arise the endospore germinates, again forming a viable vegetative cell. The presence of endospores in a bacterial culture can be detected by staining with malachite green. Because the endospore coat is so tough, steam is used to enable dye penetration.

      What color is a positive endospore stain?


      Some vegetative cells will contain spores; the cells will stain red, while the endospores will stain green.

      How do you identify an endospore?

      Endospores can also be larger or smaller in diameter than the vegetative cell. Those that are larger in diameter will produce an area of “swelling” in the vegetative cell. These endospore characteristics are consistent within the spore-forming species and can be used to identify the organism.

      What two stains are used when performing an endospore stain?

      Dorner’s Method

      • Carbolfuchsin stain.
      • A decolorizing agent (acid-alcohol)
      • A counterstain (nigrosin solution)
