Dynamic modeling of green algae cultivation in a photobioreactor for sustainable biodiesel production

Phospholipids in Algae for Biodiesel Production

Introduction Biodiesel producers have long recognized the need for new sources of oil feedstock if biodiesel is to continue displacing petroleum-based diesel fuel. One potential source of oil that could minimize competition with food crops is microbial oil, with photosynthetic algae being the most widely studied option. An understanding of algal lipids, their native biochemistry and interaction...

Reduction of water and energy requirement of algae cultivation using an algae biofilm photobioreactor.

This paper reports the construction and performance of an algae biofilm photobioreactor that offers a significant reduction of the energy and water requirements of cultivation. The green alga Botryococcus braunii was cultivated as a biofilm. The system achieved a direct biomass harvest concentration of 96.4 kg/m(3) with a total lipid content 26.8% by dry weight and a productivity of 0.71 g/m(2)...

Biodiesel Production from Macro Algae as a Green Fuel for Diesel Engine

Predictive modeling of biomass production by Chlorella vulgaris in a draft-tube airlift photobioreactor

The objective of this study was to investigate the growth rate of Chlorella vulgaris for CO2 biofixation and biomass production. Six mathematical growth models (Logistic, Gompertz, modified Gompertz, Baranyi, Morgan and Richards) were used to evaluate the biomass productivity in continuous processes and to predict the following parameters of cell growth: lag phase duration (λ), maximum specific...
