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.

Dünya üzerinde bulunan bitkilerin çoğunun hem yaraların iyileşme sürecini hızlandırmada hem de yaralanmaya bağlı enfeksiyonların tedavisinde etkili maddelere sahip oldukları bilinmektedir. Bilim insanları tarafından yapılan daha önceki çalışmalar, karayosunlarının ve ciğerotlarının da çeşitli bakteri ve mantarlara karşı antimikrobiyal ve antifungal aktiviteye sahip olduklarını göstermiştir. Bu çalışmada Philonotis seriata Mitt, Porella arboris-vitae (With.) Grolle, Porella platyphylla (L.) Pfeiff, Syntrichia calcicola J.J.Amann türlerinin etil alkol ekstraktlarının 8 gram pozitif, 9 gram negatif bakteri ve 1 maya olan toplam 18 suş üzerindeki antimikrobiyal aktivitelerinin analizi yapılmıştır. Yapılan analiz sonucunda tüm karayosunu ve ciğerotu örneklerinin birkaç suşa karşı antimikrobiyal aktiviteye sahip olduğu ve özellikle gram pozitif olan Staphylococcus aureus ve gram negatif olan Klebsiella pneumoniae üzerinde belirgin bir antimikrobiyal etki gösterdiği belirlenmiştir.

Macrofungi are good food resources, which have not only medicinal properties but are nutritive as well. Forcenturies they have been used for preventing several diseases including cancer, hypercholesterolemia andhypertension. They are also known to present antimicrobial activity, thus the aim of the present study is to putforward antimicrobial activity of ethanol extract of Leucoagaricus leucothites (Vittad.) Wasser 1977, a macrofungi and in addition to determine the chemical composition by Gas Chromatography-Mass Spectrometry.Nineteen bacteria strains and one yeast strain are used in antimicrobial screening. According to the data obtainedfrom the study L. leucothites presented both antibacterial and antifungal activity against the bacteria and yeaststrains used at different concentrations with different levels. Although there are some previous studies, it can beproposed that this study is the first detailed screening report regarding the antibacterial and antifungal potentialof L. leucothites and the compounds found in L. leucothites ethanol extract.Macrofungi are good food resources, which have not only medicinal properties but are nutritive as well.

Traditional Medicinal Uses of Mosses

The use of plants by people has a history as old as the existence of humanity. From ancient times to the present, humanity has sought solutions to diseases by making use of plants in nature. Plants that were beneficial against diseases by trial and error in the old times were recognized, used, and passed on to future generations. This process, which has been going on for centuries between plants and humans, continues as an ethnobotanical science that has been accepted worldwide today and where great resources are transferred and important researches are carried out. One of the plant groups used in the treatment of diseases is Bryophytes. Approximately 150 ethnobotanical bryophyte species are known worldwide. One of the important groups in the bryophyte division is mosses, which can live on wet grounds, in humid environments, sometimes completely submerged in water or on soil, rocks, and tree trunks in wide areas from swamps to alpine and arctic regions. Although the general characteristics of mosses vary according to different systematic schools, they are included in the Bryophyta division, which includes 1036 genera and approximately 18.409 species. Chinese and Native Americans discovered centuries ago that moss is effective in healing wounds and reducing infections in wounds. Since this discovery, mosses have been extensively studied and used in various fields. The majority of the species used are generally listed in Traditional Chinese Medicine and by Native North Americans. In this study, the use of mosses in traditional medicine is explained.
