What method requires plating cultures for counting bacteria?
The method that requires plating cultures for counting bacteria is called the colony counting method.
What method is used to distinguish the two types of bacteria?
One common method to distinguish between different types of bacteria is Gram staining. This method involves staining bacteria with crystal violet and iodine, followed by a decolorization step and counterstain. Based on whether bacteria retain the stain (Gram-positive) or not (Gram-negative), they can be differentiated.
Does pepper have the ability to kill bacteria?
Yes, pepper has antimicrobial properties that can help inhibit the growth of bacteria, but it is not a guaranteed method to kill all bacteria.
What scientist discovered a method of destroying bacteria?
Louis Pasteur is credited with discovering a method to destroy bacteria known as pasteurization, which involves heating liquids to a specific temperature to kill harmful microorganisms while preserving the product.
Both bacteria and yeast reproduce by asexual method but how does this method differ in them?
The difference in the method of reproduction amoeba and yeast, is that whereas the method of reproduction in Amoeba is binary fission, the method of reproduction in yeast is budding. The type of reproduction is called asexual reproduction.
Why some bacteria cannot be stained by grams method of staining?
Instead of one thick cell wall made of peptidoglycan they may have two thinner cell walls and the stain does not stick and is washed away.
What method requires plating cultures for counting bacteria?
The method that requires plating cultures for counting bacteria is called the colony counting method.
Difference between hot method and cold method of acid fast staining?
The hot method involves heating the stained slide with acid-alcohol to help penetrate the waxy cell wall of acid-fast bacteria, while the cold method does not require this heating step. The hot method typically yields faster results but may also lead to more fading of stain colors compared to the cold method. Both methods rely on the differential staining properties of acid-fast bacteria, such as Mycobacterium species, and non-acid-fast bacteria.
What Is a method of counting cells that have been stained or tagged with fluorescent dyes?
Flow Cytometry
What is the best method for cleaning a stained concrete floor using a stained concrete floor cleaner?
The best method for cleaning a stained concrete floor with a stained concrete floor cleaner is to first sweep or vacuum the floor to remove any loose debris. Then, dilute the cleaner according to the manufacturer's instructions and apply it to the stained areas. Use a scrub brush or mop to agitate the cleaner and lift the stains. Rinse the floor thoroughly with clean water and allow it to dry completely.
Did LC Tiffany invent the copper foil method for making stained glass pieces?
No. His asst. John La Forge was the first one to use this method.
Example of bacteria for metachromatic granules?
Corynebacterium diphtheriae is an example of a bacterium that contains metachromatic granules. These granules are composed of polyphosphate polymers and are typically observed in the metachromatic staining method where the granules appear blue or purple when stained with methylene blue.
What method of reproduction do bacteria not use?
Sexual reproduction
What is Method of asexual reproduction used by bacteria?
fission
What method do bacteria use to grow?
Bacteria multiplies by binary fission, that is a single cell divides into two.
What method is used to distinguish the two types of bacteria?
One common method to distinguish between different types of bacteria is Gram staining. This method involves staining bacteria with crystal violet and iodine, followed by a decolorization step and counterstain.

What is the method called when the bacteria sample and nutrient agar are mixed before pouring?
Pour plate method
