<b>Fungistatic activity of caffeine “in vitro” in fungi associated with coffee grains</b> - DOI: 10.4025/actasciagron.v26i3.1818
Abstract
The effect of caffeine on mycelia growth of fungi isolated from coffee was evaluated. The fungi were cultivated in decaffeinated coffee agar media added with caffeine at 0 to 1,0 %, and fungistatic effect was expressed by the size of colony diameter. The caffeine degradation by fungal activity in liquid medium was evaluated by HPLC. The antibiosis was proportional to dose, and the inhibition of growth was of 52,8 to 100% of Aspergillus flavus, 9,4 to 72,5% of Fusarium semitectum, 8,8 to 66,8% of Penicillium sp., 5,3 to 54,1% of Fusarium sp., 4,6 to 39% of A. niger and 4,7 to 37% of A. ochraceus. The inhibitory activity declined, probably due to its degradation by the fungal activity. Therefore, the fungistatic effect of caffeine may contribute for coffee quality and sanityDownloads
