Bazı Karayosunu Türlerinin İn Vitro Antimikrobiyal Aktivitelerinin Belirlenmesi

Karayosunlarının hastalıklara karşı etkisi olduğu çok uzun yıllardan beri bilinmektedir ve yaraların tedavi edilmesi ve enfeksiyonlar ile mücadele gibi alanlarda etkin olarak kullanılmaktadırlar. Bu çalışmada Plagiomnium elatum, Rhynchostegium megapolitanum, Tortella fasciculata ve Tortella tortuosa karayosunu örneklerinin etil alkol ekstraktları disk difüzyon yöntemi kullanılarak, 8 gram pozitif, 9 gram negatif bakteri ve 1 maya olmak üzere, toplam 18 mikroorganizma üzerinde test edilerek antimikrobiyal aktiviteleri belirlenmiştir. Disk difüzyon testi sonucunda tüm karayosunu örneklerinin birkaç mikroorganizmaya karşı antimikrobiyal aktiviteye sahip olduğu ve özellikle gram pozitif olan Staphylococcus aureus ATCC 25923 ve gram negatif olan Escherichia coli ATCC 25922 üzerinde belirgin bir antimikrobiyal aktivitesinin olduğu ortaya konmuştur.

Determination Of In Vitro Antimicrobial Activities Of Some Moss

Mosses have been known for many years to be effective against diseases and they are successfully used in areas such as treating wounds and fighting infections. In this study, ethyl alcohol extracts of Plagiomnium elatum (Bruch & Schimp.) T.J.Kop., Rhynchostegium megapolitanum (Blandow. ex F. Weber & D. Mohr) Schimp, Tortella bambergeri (Schimp.) Broth and Tortella tortuosa (Hedw.) Limpr were tested using disk diffusion method on a total of 18 microorganisms, 8 gram positive, 9 gram negative bacteria and 1 yeast, and their antimicrobial activities were determined. As a result of the disk diffusion test, it was demonstrated that all moss samples had antimicrobial activity against several strains, but they had significant antimicrobial activities especially on gram positive Staphylococcus aureus ATCC 25923 and gram negative Escherichia coli ATCC 25922.
