摘要
Experiments were conducted to investigate the antifungal activities of polyhexamethyleneguanidine (PHMG) derivatives introduced into polylactide (PLA), polyhydroxybutyrate (PHB) and polycaprolactone (PCL) against Aspergillus niger, Penicillium chrysogenum and Candida albicans. All of the PHMG derivatives inhibited the germination of A. niger and P. chrysogenum. All of the derivatives exerted a much stronger inhibitory effect on the cells of C. albicans. PHMG granular polyethylene wax (at the concentration of 1.0%) has a fungicidal effect. The reduction in the number of yeast cells capable of growing on the surface composites PLA, PHB and PCL with PHMG granular polyethylene wax for 24h was R>2. PHMG derivatives introduced into PLA decreased hydrolases activity in A. niger and P. chrysogenum. All of the PHMG derivatives introduced into all investigated polymers inhibited the hydrolases activity in C. albicans proportionately to concentration. PHMG granular polyethylene wax at a concentration of 1.0% most strongly inhibited hydrolases activity in yeast. The composites produced from PLA, PHB, PCL and this PHMG derivatives can be used in many areas to reduce the growth of yeast. The studied composites can potentially be used for the production of biomedical or packaging materials.Graphical AbstractPHMG derivates introduced into polymer have slightly biocidal properties against molds and strong against yeast. The composites produced from PLA, PHB, PCL and this PHMG derivatives can be used in the many areas to reduce the growth of yeast. The studied composites can potentially be used for the production of biomedical or packing materials.[GRAPHICS].
