Final answer:
The MALDI-MS technique enables the rapid identification of microorganisms by producing a unique mass spectrum, which is compared against a database to determine the microbe's identity.
Step-by-step explanation:
The macromolecule ionization method, such as MALDI-MS (Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry), allows us to obtain a mass spectrum that is unique to the microorganism being studied. By comparing this mass spectrum against a comprehensive database of known mass spectra, the identity of the microorganism can be determined. This method is routinely used in clinical microbiology labs to quickly identify microorganisms that are difficult to classify using traditional methods.
