The MIDI identification system is based on which type of analysis?

Explanation:
The MIDI identification system relies on analyzing the fatty acid composition of bacterial membranes. In practice, cells are processed to extract and convert fatty acids into fatty acid methyl esters, which are then separated and measured by gas chromatography to produce a characteristic fingerprint. This fatty acid profile is compared to a reference database to identify the organism. This chemotaxonomic approach is different from antibiotic susceptibility testing (which looks at how bacteria respond to drugs), from performing numerous biochemical reactions to create an identification profile, or from observing colony pigment patterns on chromogenic media. Therefore, fatty acid analysis is the method MIDI uses for identification.
