Chlorella sp.: A new strain with highly saturated fatty acids for biodiesel production in bubble-column photobioreactor

Rasoul-Amini, Sara; Montazeri-Najafabady, Nima; … - In: Applied Energy 88 (2011) 10, pp. 3354-3356

The biodiesel production from a naturally isolated strain of Chlorella in 2L bubble-column photobioreactor was studied. The microalgal strain was isolated from the rice paddy-field soil samples during a screening program. After 17days, at the end of exponential phase of growth, the total content...
