Differential medium is distinguishing microorganisms from one another based on growth characteristics. A medium is differential when you are able to visibly see the differences in growth patterns of organisms. Differential media include blood agar and Eosin Methylene Blue.

responses in sensitised people‚ causing respiratory diseases such as hayfever and asthma (Knox‚ Ladiges‚ Evans and Saints 2006). A variety of techniques can be used to identify the diversity and density of fungi within the Sydney Basin. The use of agar plate exposure allows microbial colonies to culture within a sterile environment. These colonies can be identified using dichotomous keys (School of Biological Sciences 2010) under compound and dissecting microscopes. This type of analysis is appropriate

The unknown bacteria A and bacteria B have to be identified by its genus and species. First both bacteria had to be inoculated into a TSA agar media using the streak plate method. Four quadrants were drawn‚ so that the bacteria could be isolated as much as possible. Each bacteria was inoculated into two different plates‚ so that one could be incubated at 37 degrees Celsius and the other at 25 degrees Celsius. Bacteria B‚ which was incubated at room temperature showed red colonies throughout its media
