Résumé

The research studies in the past focusing on finding new energy sources, were based on biodiesels which reduce the greenhouse effect by 41 % when compared with diesels. Due to this fact, many contries in the world have exempted biodiesel from taxes and encouraged their production and consumption. However, in Turkey, increase in production taxes, and because the producers can only sell their products to distribution firms, the attractiveness of biodiesel has decreased tremendously and could only been developed to the limits provided by the studies of related departments of the universities.
The recent research studies focused on alg cultures which are blue, red, green in color and are transforming CO2 to O2 in the ecosystem. The research studies on algs are implemented under two topics which are namely alg production and possibilities of using algs as fuel.
In this study, species of Dunaliella salina Palmellopsis muralis and colored light sources with different wavelengths using the 24-hour period of enlightenment, subjected to constant light intensity of cultivation under the analyzed parameters. The second experiment using white light illumination of different periods of growth parameters, cell number, pH, salinity and conductivity values were measured and analyzed. The third attempt, the temperature in the same way using white light and under constant light intensity, respectively, 21 ° C, 28 ° C and 35 oC’daki growth parameters were investigated. Finally, using white light source and 12 hours light and dark periods within 12 hours, applying a different light intensity, cell numbers, pH, salinity and conductivity values were analyzed and compared.
