Identification of unknown microorganisms - labour
As you have learned, biochemical test results can be used to identify unknown species of microorganisms. When this is done using an unidentified unknown organism, you can compare test results to many known species to determine the identity of the unknown species. You will be doing this in the Bacterial Unknowns assignment soon. First, to prepare for the process of identifying an unknown species, you must construct a dichotomous key that you will later use. It consists of a series of characteristics of which there are two varieties, so that different species can be divided based on differences in these characteristics. When constructing a dichotomous key that may be used to identify bacteria, we start by dividing a group of bacteria into two groups based on a certain characteristic, such as the Gram-stain reaction. Then, each of the two subgroups is subdivided into two groups based on a second characteristic, and so on. For example, a dichotomous key used to identify unknowns from a group of four Gram-negative cocci bacteria might look like the following:. As you can see, in order to construct a dichotomous key, you need several test results from known species.Identification of unknown microorganisms - sorry, can
Each research group was provided two eukaryotes and two prokaryotes. The unknown organisms will fall into the following classifications: bacteria, algae, fungi, or protozoans. All living organisms are organized into one of three domains of life, Bacteria, Archaea, and Eukarya. The Domain Bacteria Bacteria and Archaea are prokaryotic, which are mostly single-celled incomplex microorganisms. Both Bacteria and Archaea have a variety of prokaryotes classified in multiple kingdoms Reece, et.
