Determination of Growth Conditions for Chlorella vulgaris

Microalgae known as third generation technology for biofuel in nature are used as a renewable bioenergy source. Microalgae and crop plants have common for the production of organic compounds by using sunlight and carbon dioxide. In addition, microalgae are capable of being reproducing in the whole year allowing the more product yield than those of plants. Therefore, microalgae are more favorable feedstock since they have some advantages such as photosynthetic efficiency, biomass productivity and oil content. In this study, the most proper conditions for the growth of microalgae Chlorella vulgaris were studied. After medium optimization, at 25°C and pH of 9 using 24-hour-illuminating/day, the best growth conditions for C. vulgaris giving the maximum biomass productivity was found to be 205 mg/L for 10 days. Determination of optimal microalgal growth conditions may lead to an increase in the industrial applications of C. vulgaris.
