  Pohlia wahlenbergii (Bryophyta)’nin Biyoaktif Potansiyeli: Antioksidan, Antidiyabetik ve Antimikrobiyal Aktiviteleri

  Alataş, Mevlüt; Erdem, Belgin; Çöteli, Ebru

  Briyofitler, biyolojik aktiviteleri yeterince incelenmemiş önemli bir bitki grubunu oluşturmaktadır. Yapılarındaki çok sayıda biyoaktif bileşik, onları önemli kılmaktadır. Bu çalışmada, Pohlia wahlenbergii karayosununun aseton ve metanol özütlerinin in vitro antioksidan, antidiyabetik ve antimikrobiyal aktiviteleri değerlendirilmiştir. Antioksidan aktivitenin belirlenmesinde, bu özütlerin iki farklı radikale, DPPH. ve ABTS.+'ya karşı inhibitör güçleri ölçülmüştür. Sonuçlar, standart askorbik asit sonuçlarıyla karşılaştırıldı. Ayrıca bu ekstraktların antidiyabetik aktivitesini belirlemek için, α-amilaz enzim inhibisyonu ölçüldü. Sonuçları karşılaştırmak için akarboz ilacı kullanıldı. En yüksek DPPH. ve ABTS.+ radikal temizleme aktivitesi sırasıyla 1.509 ve 1.301 mg/mL IC₅₀ değerleriyle aseton ekstraktında gözlendi. ABTS.⁺ radikal temizleme aktivitesinin daha güçlü olduğu bulundu. Antidiyabetik aktivitenin belirlenmesinde, α-amilaz enzim inhibisyonu kullanıldı ve metanol ekstraktında en yüksek seviyede olduğu görüldü (1.792 mg/mL). Ekstraktların antioksidan ve antidiyabetik aktivitelere sahip olduğu belirlendi. Ayrıca, Pohlia wahlenbergii'den elde edilen özütlerin çeşitli patojen mikroorganizmalara karşı in vitro antimikrobiyal potansiyeli değerlendirilmiştir. Sonuçlar, güçlü antifungal aktivite göstermiştir; aseton özütü, standart ilaç Flukonazol'den daha iyi performans göstererek Candida albicans'a karşı 25 mm'lik bir inhibisyon bölgesi ve 16 µg/mL'lik bir MIC sergilemiştir. Metanol özütü de geniş spektrumlu antibakteriyel etkiler göstermiş, özellikle Bacillus cereus ve Salmonella typhimurium'a karşı 20 mm'lik bir inhibisyon bölgesi göstermiştir. Pohlia wahlenbergii'nin seçici antimikrobiyal özellikleri, yeni doğal antibiyotikler ve antifungal ajanlar geliştirmek için potansiyel bir kaynak olduğunu göstermektedir.

  Phenolic Profiling of Some Bryophyte Species: In Vitro and In Silico Assessment of Their Antimicrobial Potentials

  Çambay, Zafer; Uslu, Harun; Coteli, Ebru; Göktaş, Bünyamin; Özdemir Bayçinar, Kevser; Emre, Mustafa Yunus; Güngören, Muhammed; Alataş, Mevlüt

  This study explores the phytochemical composition and antimicrobial potential of Palustriella commutata, Philonotis calcarea, Cinclidotus riparius, Rhynchostegium riparioides, Plagiomnium ellipticum, and Porella platyphylla, with a focus on bryophyte species phenolic constituents and biological activities. HPLC analysis identified seven phenolic acids (4-hydroxybenzoic acid, 2,5-dihydroxybenzoic acid, 3,4-dihydroxybenzoic acid, caffeic acid, vanillic acid, syringic acid, and p-coumaric acid) across all species in varying concentrations. In in vitro antimicrobial tests, the bryophyte extracts used showed significant activity against Pseudomonas aeruginosa (ATCC 9027), while exhibiting relatively lower inhibition against Staphylococcus aureus (ATCC 25923). The study showed that all species extracts exhibited comparable activity to erythromycin against P. aeruginosa, while Cinclidotus riparius and Plagiomnium ellipticum extracts showed no activity against S. aureus, and the remaining species exhibited lower activity compared to erythromycin. Molecular docking studies demonstrated strong binding affinities of these phenolics to the active site of the target macromolecule (PDB ID: 3FRQ), suggesting meaningful interactions with residues such as ARG122 and ASN123, similar to erythromycin binding patterns. The findings indicate that bryophyte-derived phenolic compounds possess significant antimicrobial potential and may serve as promising candidates for the development of novel bioactive agents. This study provides a broad framework for the insufficiently researched antimicrobial potential of bryophytes by establishing direct links between species-specific phenolic fingerprints, experimentally observed antibacterial activities, and predicted receptor-level interactions. Further complementary biological studies are needed to confirm and expand upon these results.

Hedenäs, previously known only from Çanakkale, and the arctic-alpine moss Cyrtomnium hymenophylloides (Hübener) T.J.Kop., previously known only from Ordu province, were rediscovered in Türkiye. Scorpidium cossonii was collected on wet rocky bank near the Ciğer Lake (Çan-Çanakkale) in 2014. Cyrtomnium hymenophylloides was collected on wet soil in Kalıcak and Kadıncık Villages (Ulubey-Ordu) in 2014. Ten years later, both species were found the vicinity of Karagöl and Çiniligöl (Ulukışla-Niğde), glacial lakes located in the Central Anatolian part of the Bolkar Mountains. Scorpidium cossonii and Cyrtomnium hymenophylloides were recorded for the second time from Türkiye and Southwest Asia with the present study. While, Scorpidium cossonii is characterised by strongly curved non-plicate leaves and well developed hyalodermis, Cyrtomnium hymenophylloides is characterised erect tuft life form, broadly ovate leaves, acute to apiculate leaf apices. These new locality records will provide important information about the geographical distribution of the both species in Anatolia and will contribute to the bryophyte flora of Türkiye.

  The Epiphytic Bryophyte Vegetation of the Karçal Mountains (Artvin, Türkiye)

  Batan, Nevzat; Özcan, Osman; Ezer, Tülay; Erata, Hüseyin; Alataş, Mevlüt

  Abstract: In this study, the epiphytic bryophyte vegetation of the Karçal Mountains (Artvin) in the Caucasus Region was investigated. Relevés collected from living tree trunks during various vegetation periods in 2022 were analyzed using the Braun-Blanquet method and multivariate analysis techniques. As a result, Anomodontetum attenuati-Ulotetosum crispae subass. nov. was described and characterised as a new epiphytic syntaxa. In addition, Orthotrichetum rupestris, Orthotrichetum speciosi, Uloto crispae-Orthotrichetum striati, and Anomodonto viticulosi-Leucodontetum sciuroidis-Anomodontetosum attenuati were determined for the first time in Türkiye. All syntaxa were presented by analyzing them in terms of their ecological and floristical classifications.

  Alataş, Mevlüt; Sahilli, Yeliz Cakir

  In this study, antioxidant, fatty acid, mineral analysis and some chemical properties of Polytrichum piliferum, a species of moss, were investigated. As a result of the research, it was determined that P. piliferum extract had a moderate effect in terms of antioxidant properties and total phenolic content. Regarding fatty acid compositions, oleic and palmitic acids were found to be high. As a result of mineral analysis, it was found that it could accumulate high levels of aluminum (Al), iron (Fe), calcium (Ca) and potassium (K).
