QUINTANA-OBREGON, Eber A.; PLASCENCIA-JATOMEA, Maribel; GONZALEZ-AGUILAR, Gustavo A  and  CORTEZ-ROCHA, Mario O.. Growth inhibition of Penicillium chrysogenum with oils of Cinnamomum zeylanicum, Allium cepa and Cymbopogon citratus. Rev. Mex. Mic [online]. 2010, vol.32, pp.59-62. ISSN 0187-3180.

The antifungal effects of essential oils of Cinnamomum zeylanicum, Allium cepa and Cymbopogon citratus were evaluated on Penicillium chrysogenum spore germination and radial growth. It was determined that the minimum inhibitory concentrations 50 (CR₅₀) were 294±16, 152±7 and 112±3 ppm of Cinnamomum zeylanicum, Cymbopogon citratus and Allium cepa, respectively. The three oils significantly inhibited the spore germination and radial growth compared to controls. We recommended its use for further study for food protection.

Keywords : spore germination; radial growth; antifungal activity.
