Oil content and composition, biomass productivity and adaptability to different growth conditions are important parameters in selecting a suitable microalgal strain for biodiesel production. Here, we describe isolation and characterization of three green microalgal species from geothermal flora of Central Anatolia. All three isolates, namely, Scenedesmus sp. METUNERGY1402 (Scenedesmus sp. ME02), Hindakia tetrachotoma METUNERGY1403 (H. tetrachotoma ME03) and Micractinium sp. METUNERGY1405 (Micractinium sp. ME05) are adaptable to growth at a wide temperature range (25-50 degrees C). Micractinium sp. ME05, particularly has superior properties for biodiesel production. Biomass productivity, lipid content and lipid productivity of this isolate are 0.17 g L (1) d (1), 22.7% and 0.04 g L (1) d (1), respectively. In addition, Micractinium sp. ME05 and Scenedesmus sp. ME03 mainly contain desirable fatty acid methyl esters (i.e. 16:0, 16:1, 18:0 and 18:1) for biodiesel production. All isolates can further be improved via genetic and metabolic engineering strategies.

Deriving strategy and developing balanced scorecard for General Directorate of Environmental Impact Assessment and Planning in the Ministry of Environment and Forestry
Özcan, Mehmet; Saatçioğlu, Ömer; Department of Industrial Engineering (2003)
In this study, it is aimed to derive strategies and develop a Balanced Scorecard in General Directorate of Environmental Impact Assessment and Planning in Ministry of Environment and Forestry. Firstly, the objectives of the General Directorate defined in the law are reassessed and strategies to realize the objectives are derived by making use of feedback received by conducting surveys to 4 main stakeholder groups which are the staff of the General Directorate, Provincial Directorates, companies preparing EI...
A technical feasibility study on the use of Çavundur geothermal field for greenhouse heating
Kasapoğlu, Hüseyin; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2003)
Protective cultivation is widely used nowadays in order to increase crop yield by creating the optimum conditions such as temperature, humidity and CO2 content, irrespective of outside conditions. Since plant production doubles for every 10 degrees increase in temperature to a certain limit, this makes temperature a very important factor for optimum plant growth. In order to keep the greenhouse temperature constant during changes in outside conditions, heating and often cooling are required. Heating of a gr...
Comprehensive spectral and thermal characterization of oil shales
Güven, Selin; Akın,Serhat; Hasçakır, Berna (Society of Petroleum Engineers; 2015-01-01)
The heterogeneous nature of oil shale resources associated to the depositional environments, lithology, and organic content make the reserve estimation complex and unpredictable. However, comprehensive laboratory studies on organic rich shale samples collected from different regions can increase the understanding about the organic content of oil shales, interaction of shale with organic matter and injected fluid used during enhanced oil recovery method. This study investigates the characterization of eight ...
Evaluation of novel thermo-resistant Micractinium and Scenedesmus sp for efficient biomass and lipid production under different temperature and nutrient regimes
Sonmez, Cagla; ELÇİN, EVRİM; Akin, Dilan; Öktem, Hüseyin Avni; Yücel, Ayşe Meral (2016-07-01)
Despite the vast interest in microalgae as feedstock for biodiesel production, relatively few studies examined their response to diurnal temperature fluctuation. Here, we describe biomass and lipid productivities and fatty acid profiles of thermo-resistant Micractinium sp. and Scenedesmus sp. grown in batch cultures in a laboratory set-up that mimics a typically warm summer day in Central Anatolia with a 16-h light temperature of 30 degrees C and 8-h dark temperature of 16 degrees C (30 degrees C (day)/16 d...
Carbon-based conductive materials enhance biomethane recovery from organic wastes: A review of the impacts on anaerobic treatment
Kutlar, Feride Ece; Tunca, Berivan; Yılmazel, Yasemin Dilşad (2022-03-01)
Amongst the most important sustainable waste management strategies, anaerobic biotechnology has had a central role over the past century in the management of high-pollution load sources, such as food, agricultural and municipal wastes. During anaerobic digestion (AD), valuable by-products such as digestate and biogas are produced. Biogas (mainly composed of methane) is generated through a series of reactions between bacteria and archaea. Enhancement of AD process with higher methane yield, accelerated metha...
