Abstract

This study was performed in order to bring out a detailed information on growth dynamics and biochemical determination of the diatom species Nitzschia palea (Kützing) W. Smith under batch culture conditions in order to pave the way for further studies. The study material was isolated from a fresh water sample collected from Ankara, Turkey. The diatoms were cultured in Allen medium for 168 hours and the growth dynamics were determined by cell density and dry weight analyses. Specific growth rate, duplication time of the culture and biochemical compositions were also investigated. Molecular characterization of the N. palea strain was performed by applying Fourier Transform Infrared Spectroscopy. The cell density and the dry biomass of the culture at the end of the 168 hours incubation period was determined as 2.0x106±1.0x105cells/mL and 0.212±0.041 g L-1, respectively. The algal specific growth rate was found as 0.010 h-1 at 96-h and the doubling time was calculated as 68 h-1. The protein content was measured as 41.21%, carbohydrate content as 21.74%, lipid content as 16.84% and ash content as 19.88%. These results indicated that N. palea may be used in different fields of industries, especially in biodiesel production.

Abstract

Bu çalışma, daha ileri
çalışmaların önünü açmak amacıyla yığın kültür koşullarında, Nitzschia palea
(Kützing) W. Smith diatom türünün biyokimyasal tayini ve büyüme dinamikleri
hakkında ayrıntılı bilgi vermek amacıyla yapılmıştır. Çalışma materyali,
Ankara, Türkiye'den toplanan tatlı su örneğinden izole edilmiştir. Diatom
kültürü Allen besi ortamında 168 saat boyunca yetiştirilmiş ve büyüme
dinamikleri hücre yoğunluğu ile kuru ağırlık analizleriyle belirlenmiştir.
Spesifik büyüme hızı, kültürün ikilenme süresi ve biyokimyasal bileşimleri de
incelenmiştir. Nitzschia palea’nın moleküler karakterizasyonu Fourier
Transform Infrared Spektroskopisi kullanılarak gerçekleştirilmiştir. Ekimi
takip eden 168. saatte, Allen besi kültür ortamında kültürlerin hücre yoğunluğu
2,0x106±1,0x105 hücre/mL ve kuru biyokütlesi 0,212±0,041
(g L-1) olarak tespit edilmiştir. Nitzschia palea’nın
spesifik büyüme oranı 96. saatte (0,010 h-1) ve ikilenme süresi 68 h-1
olarak hesaplanmıştır. Nitzschia palea’nın protein miktarı (%41,21),
karbonhidrat miktarı (%21,74), lipit miktarı (%16,84) ve kül miktarı (%19,88)
olarak belirlenmiştir. Bu sonuçlar, N. palea'nın farklı endüstri
alanlarında özellikle biyodizel üretimi için kullanılabileceğini göstermiştir.
