There are many ways to identify an unknown bacteria. The method to identify depends on tools available and setting. A medical setting has different identification process than an educational setting. Both places would usually begin with a gram stain. A gram positive bacteria would appear purple under a microscope, whereas gram negative would appear orange. Another way to identify bacteria would be to choose different agar plates to grow the bacteria. The presence of bacterial growth on different media helps to identify the unknown bacteria.

Why do you think nitrification requires two different types of bacteria?

nitrification is a 2 step process the first step is the oxidation of ammonia into nitrate the second step is the oxidation of nitrate into nitrite since these are 2 separate steps, there is no microorganism in existence that can carry out both steps instead, the first step usually uses Nitrosomonas or Nitrococcus bacteria the second step usually uses Nitrobacter bacteria


Why would you want to know if a gram stain is positive or negative?

Gram negative bacteria (pink gram stain) contain no outer cell membrane, while gram positive bacteria (purple gram stain) do contain an outer cell membrane. Gram negative and positive bacteria can respond differently to antibiotics. Many only work on only one of the two bacteria types. A gram stain is also the first step in identifying a bacteria, dividing bacteria into two large and distinct groups.


What are the two steps in the process of identifying hair with a light microscope?

The first step is to examine the diameter of the hair shaft. This helps determine whether the hair is human or animal. The second step is to analyze the cuticle scale pattern, which can provide information on the species of animal or individual characteristics of the hair.


Which step is the most crucial or most likely to cauce poor result in the gram stain why?

The most crucial step in the Gram stain process is the decolorization step, typically done with ethanol or acetone. If this step is performed too briefly, Gram-positive bacteria may not lose their crystal violet stain and appear falsely Gram-positive. Conversely, if decolorization is prolonged, Gram-negative bacteria may lose their stain and appear falsely Gram-positive, leading to inaccurate results in identifying bacterial types. Proper timing and technique during this step are essential for accurate Gram classification.
