The antifungal activity of the Polyhexamethylene-guanidine hydrochloride (PHMGH)-based disinfectant against fungi isolated from papaya fruit was evaluated. The aim of this work was to show that the PHMGH can be used as a disinfectant for papaya preservation. Thirty one strains of fungi were isolated as Mucor sp., Botrytis sp., Penicillium sp., Geotrichum sp., Aspergillus sp. and Colletotrichum sp. Mucor sp. was the most isolated with a frequency of 52.77% followed by Botrytis (47.22%), Aspergillus and Penicillium (8.33%), Colletotrichum (5.56%) then, Geotrichum (2.78%). The antifungal activity of the PHMGH was tested through the determination of the minimal inhibitory concentrations (MICs) and the minimal fungicidal concentrations (MFCs). All the strains tested were sensitive to the disinfectant. However, the activity of PHMGH varies according to the strain tested. The values of the MIC and the MFC were between |
