    (ACADEMIC JOURNALS, 2011) Elibol, Busra; Ezer, Tulay; Kara, Recep; Celik, Gokcen Yuveli; Colak, Emel
    In this study, the antifungal and antibacterial effect of 6 different acrocarpous mosses were tested in vitro aganist 8 different microorganisms. For the extraction, ethyl alcohol, methyl alcohol, acetone and chloroform were used as solvents. While the highest antimicrobial effect was seen in methyl alcohol extracts, extracts of chloroform showed the lowest level of antimicrobial effect. Grimmia anodon Bruch & Schimp. which is one of the acrocarp mosses used in this study, showed the highest activity in terms of the number of microorganism affected. Tortella tortuosa (Hedw.) Limpr. only has effect on Candida albicans ATCC 16231 strain. All the results were compared with standard antibiotic discs, ketoconazole (50 mu g), ampicillin (10 mu g), eritromycin (15 mu g) and vancomycin (30 mu g).

    Investigation of antimicrobial activity of some Turkish pleurocarpic mosses
    (ACADEMIC JOURNALS, 2011) Colak, Emel; Kara, Recep; Ezer, Tulay; Celik, Gokcen Yuvali; Elibol, Busra
    In this study, the antimicrobial activities of different extracts from the five pleurocarpic mosses (Platyhypnidium riparioides (Hedw.) Dixon, Leucodon sciuroides (Hedw.) Schwagr., Hypnum cupressiforme Hedw., Homalothecium sericeum (Hedw.) Br.Eur., and Anomodon viticulosus (Hedw.) Hook & Taylor.) were tested aganist eight bacterial and fungal strains. For the extraction, four different solvents (ethyl alcohol, methyl alcohol, chloroform and acetone) were used. While methanolic extracts of P. riparioides showed the highest antibacterial effect against the Gram-negative bacterium Pseudomonas aeroginosa ATCC 27853, acetone extract of A. viticulosus showed the highest antifungal effect against the fungus Saccharomyces cerevisiae ATCC. All the results were compared with standard antibiotic discs: ketoconazole (50 mu g), amphicillin (10 mu g), eritromycin (15 mu g), penicillin (10 mu g) and vancomycin (30 mu g).
