Türkiye’de Doğal Yayılışa Sahip Karayosunlarından Sphagnum centrale C.E.O. Jensen ve S. nemoreum Scop. ’in (Bryophyta) Antibakteriyal Aktivitelerinin Belirlenmesi

Last two decades, a very large group of organisms including flowering plants, non-flowering plant groups, fungi, algae and cyanobacteria have been researched medically, the effects of these organisms against pathogenic microorganisms have been examined and remarkable results have been obtained. The bryophytes that constitute our research topic are the second largest group of plant represented by approximately 1030 taxa in our country. Especially in recent years, besides the systematic studies, there is a significant increase in the studies carried out on phytosociology, ecology, molecular taxonomy and medicinal properties. It has been found that extracts prepared from bryophytes are antimicrobial effective against some Gram (-) and Gram (+) bacteria species. Therefore, the antimicrobial effect of two different mosses belonging to the genus Sphagnum (Sphagnopsida) which are S.centrale and S.nemoreum on various Gram (-) and Gram (+) bacteria were investigated. The effect of different extracts obtained from two Sphagnum species on these organisms was checked by selecting the bacteria which are important for food safety and clinically important groups. It was determined that extracts obtained from both mosses were effective on Listeria monocytogenes and L. innocua strains, while Sphagnum nemoreum extracts were also effective on Staphylococcus aureus.
