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.

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 ...
Etherification of biodiesel by-product glycerol to produce fuel oxygenates
İkizer, Burçin; Doğu, Timur; Oktar, Nuray; Department of Chemical Engineering (2014)
Biodiesel, which is a renewable and environmentally friendly alternative to petroleum based diesel fuel, is produced by trans-esterification of vegetable oils and animal fats with lower molecular weight alcohols (methanol/ethanol), in the presence of a basic catalyst. Glycerol is the main side product of biodiesel production process. Economics of biodiesel production strongly depends upon the efficient utilization of its byproduct glycerol. The most attractive utilization way is its etherification for the p...
The feasibility study for an enhanced geothermal system application in Dikili-İzmir region

For Turkey, one sustainable way to increase the clean energy share in the power generation can be the utilization of geothermal resources as they are abundant, reliable, domestic and able to provide base load. This study aims to investigate the untapped potential of hot dry rock systems to generate power. Dikili-İzmir geothermal field is selected as a case study with four different production scenarios. Accessible resource base and recoverable heat energy are calculated by employing a probabilistic approach...

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...
