    Bazı yabani makrofungus misellerinin antimikrobiyal aktivitelerinin belirlenmesi
    (Selçuk Üniversitesi, Mantarcılık Uygulama ve Araştırma Merkezi Müdürlüğü, 2010-04) Kalyoncu, Fatih; Oskay, Mustafa; Kalmış, Erbil
    Bu çalışmada, Türkiye'nin özellikle Akdeniz bölgesinden toplanan 21 yabani makrofungus türünden (Agaricus bresadolanus, Auricularia auricula-judae, Chroogomphus rutilus, Fomes fomentarius Ganodermalucidum, Gloeophyllum trabeum, Gymnopus dryophilus, Infundibulicybe geotropa Inocybe flocculosa var. crocifolia Inocybe catalaunica Lentinula edodes, Lentinus sajor-caju, Lycoperdon excipuliforme Macrolepiotaexcoriata, Morchella esculenta var. rigida Morchella intermedia Omphalotus olearius Pleurotus djamor,Postia stiptica, Rhizopogon roseolus ve Stropharia inuncta) elde edilen misellerin antimikrobiyal aktivitepotansiyelleri araştırılmıştır. Antimikrobiyal aktivitenin belirlenebilmesi için misellerin etanol ekstreleri agarkuyucuk difüzyon yöntemi ile 11 test mikroorganizmasına karşı denenmiştir. Çalışma neticesinde, kullanılan makromantar türleri içinde Ganoderma lucidum en etkili tür olarak belirlenmiştir.

    Composition, antioxidant, antimicrobial and enzyme inhibition activities of two Origanum vulgare subspecies (subsp vulgare and subsp hirtum) essential oils
    (ELSEVIER SCIENCE BV, 2015) Sarıkürkcü, Cengiz; Zengin, Gökhan; Oskay, Mustafa; Uysal, Şengül; Ceylan, Ramazan; Aktümsek, Abdurrahman
    Essential oils (EOs) from Origanum vulgare subsp. vulgare (OW) and O. vulgare subsp. hirtum (OVH) were evaluated for antioxidant activities (DPPH, ABTS, FRAP, CUPRAC, beta-carotene/linoleic acid, phospho-molybdenum and metal chelating), antimicrobial and inhibitory properties against acetylcholinesterase, butrylcholinesterase, tyrosinase, alpha-amylase and alpha-glucosidase. Thymol and linalool were identified as major component in OW and OVH essential oils, respectively. O. vulgare subsp. vulgare exhibited a strong free radical scavenging, reducing power, antimicrobial and acetylcholinesterase, butrylcholinesterase, alpha-amylase and alpha-glucosidase inhibitory activity. Interestingly, OVH possess a significant metal chelating and tyrosinase inhibitory activities. The EOs of both species exhibited moderate antibacterial and antifungal activities. The MIC values of the EOs ranged from 85.3 to 426.7 mu g/mL. O. vulgare subsp. vulgare showed higher activity against Sarcina lutea with the lowest MIC (85.3 mu g/mL), whereas OVH indicated strong activity for Candida albicans with MIC value of 85.3 mu g/mL. The data suggest that the Origanum EOs could be used as valuable new natural agents with functional properties for food and pharmacology industries. (C) 2015 Elsevier B.V. All rights reserved.
