Final answer:
Microorganisms with polar plugs can be identified with fecal flotation or centrifugation tests, using lipid composition analyses like PLFA and FAME to compare with known profiles.
Step-by-step explanation:
The microorganism in question can be easily identified on a fecal flotation or centrifugation by its polar plugs. Specific microbes are recognized through various laboratory techniques, such as phospholipid-derived fatty acid (PLFA) analysis and fatty acid methyl esters (FAME). PLFA and FAME profiles are compared with known microorganisms to identify unknown species. Membranes that predominantly consist of phospholipids can be hydrolyzed to release fatty acids for FAME analysis. Distinguishing characteristics such as polar plugs are identifiable during detailed analysis of the samples.
