You make a 1:100 dilution of your culture and plated 0.1 ml of this sample on a Nutrient agar plate. After incubation, you counted 50 colonies on the plate. How many organisms were in the original culture?
After quick-characterization by staining, specialized growth media can be used to indicate further biochemical characteristics of an unknown organism. These tests use visual outcomes, such as colors, patterns, and changes in appearance. The results can be interpreted to then assign a characteristic to the unknown organism. For example, a color change may happen when an unknown organism is incubated in a mixed sugar broth. The color could indicate which sugar was (or was not) used by the bacterium for energy. a) explain in your own words how to perform specialized media tests to find an unknown bacteria
