Resistance to molds of flax-fiber based materials

Popis výsledku v původním jazyce

In the present study, the prepared covering material based on flax fibers containingcaffeine, nano-copper, or corundum (Al2O3) as a potential biocidal substance was prepared andtested on biological resistance. Two experimental designs were performed: a) the samples wereplaced in a desiccator at the air humidity of about 90 % and at a temperature of 25 °C for onemonth. The samples were then transferred to sterile agar and the coverage of the agars and thesamples with molds were observed after a week of incubation. All samples were found to beinfected. The samples containing copper were the least resistant. b) The samples were placed onsterile agar and the petri dishes were subjected to the fallout method, where both the samples andthe agars were insulted by mold spores from the air. The Petri dishes with the samples were thenplaced in a thermostat in the dark at 25 °C for a week. After the end of the exposure, the samplesand agars were observed. The samples were covered by molds with an increasing intensity in thefollowing rank: caffeine sample = corundum sample < Cu sample = control sample = pure flax fibers.
