Abstract

ABSTRACT Geotrichum candidum can produce and excrete compounds that inhibit Listeria monocytogenes . These were purified by ultrafiltration, centrifugal partition chromatography, thin-layer chromatography, gel filtration, and high-pressure liquid chromatography, and analyzed by liquid chromatography-mass spectrometry, infrared spectrometry, nuclear magnetic resonance spectrometry, and optical rotation. Two inhibitors were identified: d -3-phenyllactic acid and d -3-indollactic acid.
