Distinct spectral differences among Saccharomyces cerevisiae, Corynebacterium glutamicum, Escherichia coli, Staphylococcus aureus were observed from their high quality infrared spectra in the frequence regions 900-1 800 cm -1 and 2 800-3 050 cm -1 . These differences imply that it is possible to use FTIR to analyze and identify microbes. And this method will be a simple, rapid and accurate one.
