Worldwide, microalgal biofuel production is being investigated. It is strongly debated which type of production technology is the most adequate. Microalgal biomass production costs were calculated for 3 different micro algal production systems operating at commercial scale today: open ponds, horizontal tubular photobioreactors and flat panel photobioreactors. For the 3 systems, resulting biomass production costs including dewatering, were 4.95, 4.15 and 5.96 € per kg, respectively. The important cost factors are irradiation conditions, mixing, photosynthetic efficiency of systems, medium- and carbon dioxide costs. Optimizing production with respect to these factors, a price of € 0.68 per kg resulted. At this cost level microalgae become a promising feedstock for biodiesel and bulk chemicals.
Summary
Photobioreactors may become attractive for microalgal biofuel production. 相似文献2.

The effect of shear stress on the viability of Chaetoceros muelleri was studied using a combination of a rheometer and dedicated shearing devices. Different levels of shear stress were applied
by varying the shear rates and the medium viscosities. It was possible to quantify the effect of shear stress over a wide
range, whilst preserving laminar flow conditions through the use of a thickening agent. The threshold value at which the viability
of algae was negatively influenced was between 1 and 1.3 Pa. Beyond the threshold value the viability decreased suddenly to
values between 52 and 66%. The effect of shear stress was almost time independent compared to normal microalgae cultivation
times. The main shear stress effect was obtained within 1 min, with a secondary effect of up to 8 min. 相似文献
