摘要
Intensive studies are being conducted to improve alternative energy resources due to a significant increase in the risks arising from the use of oil based energy in recent years. Biomass, ethanol and biodiesel are the most important alternative energy resources are renewable, recyclable and non-polluting. Biodiesel has caused an increase in food prices and has made it difficult to obtain food in some less developed countries, due to the allocation of agricultural land for the cultivation of oil crops rather than food production, to gain more profit. Therefore, microalgae, which can grow easily in fields not used for agriculture and for which per hectare yield is very high when compared with other biodiesel resources; appear to be a new biodiesel resource.
In this study, the Chlorella protothecoides species belonging to the class Chlorophyceae were examined, suitability for biofuel production, large amount of oil, different temperature requirements. The effect of some growing parameters of this species, on different light intensity (172 lux, 186 lux and 265 lux) and different light cycles (12/12, 18/6, 6/18 and 24/0) on cell numbers, pH and conductivity values, has been investigated. According to the results of this study, it was determined that the effect of both light cycles and light intensity are important for cell numbers, pH, conductivity and salinity values.
