In this study, chitin and chitosan were obtained from the cell wall of two different mushroom species using chemical method and physicochemically characterized. The dry weight chitin contents of the mushroom species were determined as 11.4% for Lactarius vellereus and 7.9% for Phyllophora ribis. Chitosan yields of the chitins isolated from L. vellereus and P. ribis were 73.1% and 75.3%, respectively. While, the maximum degradation temperatures of vellereus and P. ribis chitins were found to be 354 degrees C and 275 degrees C by thermogravimetric analysis (TGA), the maximum degadation temperature of the chitosans obtained from these chitins were recorded as 262 degrees C and 229 degrees C, respectively. The crystalline index values of L. vellereus and P. ribis chitins were calculated as 64% and 49%, respectively according to the X-ray diffraction analysis (XRD) results. The scanning electron microscopy (SEM) indicated that there were no nanofiber or nanopores on the surface of the chitins and chitosans obtained from these two mushroom species. The results of this study revealed that L. vellereus and P. ribis had higher chitin contents than some other insects and mushroom species recorded in the literature and these species may be used as a potential chitin sources.Öğe Frequency dependent dielectric properties of biomimetic growth chitin [Biyomimetik Olarak Buÿütülmüs Kitin Nanofiberlerin Dielektriksel Özelliklerinin Frekansa Bagliligi](Institute of Electrical and Electronics Engineers Inc., 2016) Arslan, Semra; Kaya, Murat; Baştu?, Arif; Çankaya, G.Bu çalışmanın amacı, 100 Hz ile 1 MHz frekans aralığında çalışılarak, biomimetik olarak büyütülmüş kitin nanofiberlerin elektriksel özellikleri hakkında bilgi edinmekti. Dielektrik ölçümler, HIOKI "3532-50 LCR HiTESTER" ve özel olarak tasarlanmış, aynı zamanda numunenin kalınlığını ölçen bir probe sistemi kullanılarak yapılmıştır. Numuneler levha şeklinde hazırlanmıştır. Yapılan testler sonucunda malzemelerin; kapasitans, iletkenlik, dielektrik sabiti, ve kayıp katsayısı frekans değişimine göre grafiği ile kapasitansın voltaj değişimine göre grafiği çizilmiştir.Öğe Production and monomer compositions of exopolysaccharides by Propionibacterium spp. isolated from Turkish Traditional cheese(Elsevier, 2009) Yüksekdağ, Zehranur; Darılmaz, Derya Önal; Beyatlı, Yavuz[Abstract Not Available]Öğe Acid productions and antimicrobial activities of propionibacterium strains(Elsevier, 2009) Yüksekdağ, Zehranur; Önal Darılmaz, Derya; Beyatlı, Yavuz[Abstract Not Available]
