Airlift photo-bioreactors for Chlorella vulgaris cultivation in closed-loop zero waste biorefineries

Batch and Continuous Studies of Chlorella Vulgaris in Photo-Bioreactors

Mixotrophic cultivation of Chlorella vulgaris using industrial dairy waste as organic carbon source.

Growth parameters and biochemical composition of the green microalga Chlorella vulgaris cultivated under different mixotrophic conditions were determined and compared to those obtained from a photoautotrophic control culture. Mixotrophic microalgae showed higher specific growth rate, final biomass concentration and productivities of lipids, starch and proteins than microalgae cultivated under p...

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...

Airlift Bioreactors: Review of Recent Advances

1 The present review roughly covers the publications that have appeared since Prof. K. Schügerl delivered a keynote address at the 4th GLS International Conference in 1997 (Schügerl, 1997). It includes publications that deal with gas/liquid systems without solids, but gives an extra weight to applications of airlift bioreactors to wastewater treatment and to algal growth. Three extensive review...

Stem cell cultivation in bioreactors.

Cell-based therapies have generated great interest in the scientific and medical communities, and stem cells in particular are very appealing for regenerative medicine, drug screening and other biomedical applications. These unspecialized cells have unlimited self-renewal capacity and the remarkable ability to produce mature cells with specialized functions, such as blood cells, nerve cells or ...
