    In the present study, antimicrobial activity of raw skin and chrome-tanned leather samples treated with acetone and chloroform extracts of Pseudevernia furfuracea (L.) Zopf were tested against Bacillus subtilis (ATTC 6633), Bacillus cereus (CCM 99), Staphylococcus aureus (ATCC 6538-P), Escherichia coli (ATCC 11228), Enterococcus faecalis (ATCC 29212), Klebsiella pneumoniae (CCM 2318), Pseudomonas aeruginosa (ATCC 27853), Aspergillus niger, Aspergillus fumigatus, Aspergillus candidus, Aspergillus flavus, Penicillium jensenii, Geotrichum candidum and Candida albicans by the disc diffusion method. The study showed that acetone and chloroform extracts of Pseudevernia furfuracea (L.) Zopf had antimicrobial activity on raw skin and chrome-tanned leather. The inhibition zones of both extracts for the bacteria and fungi tested were found to vary between 11.0 mm to 31.0 mm in raw skins, but between 11.2 mm and 29.0 mm in chrome-tanned leathers.
