Abstract: We use the power density spectra obtained by fluctuation-enhanced sensing ofbacterial odors Escherichia coli and Anthrax-surrogate Bacillus subtilis togenerate new, highly distinguishable, types of patterns based on the averageslope of the spectra in different frequency ranges. Such plots can beconsidered as -fingerprints- of bacterial odors. Three different ways ofpattern generation are tested, including a simple binary version. The obtainedpatterns are simple enough to identify the situation by the naked eye without apattern recognizer.
