Novel way to reduce energy consumption
Current criteria in selecting the host organism for a successful algae biodiesel plant includes: i) photosynthetic efficiency to obtain high biomass yield from light, ii) biomass growth rate, iii) oil content of the biomass, iv) temperature tolerance, v) the value of biomass residue and byproducts, vi) the ease of extraction, purification, and conversion process [2,5]. However, little research has been done on the maximum cell density and morphology's impact on the demanding auxiliary energy require for an algae biodiesel plant. Instead, the solution to the auxiliary energy problem is focus mainly on the photobioreactor design [7]. Using the microalgae strain that fulfill the traditional criteria in host selection as well as favorable rheological properties in a photobioreactor with high biomass concentration can significantly reduce the pump power consumption but maintain the algae overall productivity. This can make algae biodiesel a more competitive alternative fuel.
