摘要：Algal production is the most effective and economical option for eutrophication control, waste water treatment and the conversion of solar energy into biomass. In Turkey, annual solar radiation averages approximately 1200-2000 kWh/m2 and producing green energy through biomass with microalgal photosynthesis, by using solar energy, will help reduce damage to the environment. This study was conducted under laboratory conditions established in Dicle University, Faculty of Agriculture, Agricultural Machinery and Technology Engineering Department. The Chlorella protothecoides species belonging to Chlorophyceae class was investigated by taking some factors, such as suitability for biofuel production, a large amount of oil and different temperature requirements into account. The effects of different growing parameters, such as light sources with different wavelengths (blue, yellow, red and white), at different temperatures (20 °C, 25 °C and 30 °C), on cell numbers, pH and conductivity values, were investigated. In experiments evaluating the different colors of light, the highest pH value was found with white light, as 8.326 and the lowest pH value was found with yellow light, as 6.890, respectively. The highest salinity value was found at white light, as 369.8 mg/L and the lowest salinity value was found at yellow light, as 305.3 mg/L, respectively. The highest conductivity was found with white light, as 692.4 ^S/cm and the lowest conductivity was found with yellow light, as 572.5 ^S/cm, respectively. The largest cell numbers were obtained were 1204000 pcs/mm3 with white light, whereas the lowest cell numbers obtained were 530300 pcs/mm3 with yellow light. Under these conditions, decreases were observed with increasing temperature. An increase in the number of days resulted in an increase in overall properties examined with the exception of experiments at 30oC.
