Biogenic
silver nanoparticles (AgNPs) were obtained throughout the fungal
biosynthesis using extracellular filtrate of the epiphytic
fungus B. ochroleuca and were incorporated in cotton and
polyester fabrics by common impregnation
procedure that was repeated once, twice or four times. Both fabrics were analyzed by
scanning electron microscopy (SEM), and the
effectiveness of impregnation was determined using inductively coupled
plasma optical emission
spectrometry (ICP OES). The AgNPs loaded fabrics showed potent antimicrobial activity on
Staphylococcus aureus and
Escherichia coli as well as on clinically relevant
Candida albicans,
Candida glabrata, and
Candida parapsilosis, indicating that the AgNPs impregnation of cotton and
polyester fabrics was efficient. AgNPs effectively inhibited the
biofilm formation by
Pseudomonas aeruginosa and was not toxic to Galleria mellonella
larvae indicating a promising
probability of biotechnological application.
