We describe the use of a novel, computerized, multiple outdoor microalgal growth system to achieve conditions maximizing high photosynthesis and biomass production rates. We applied this system to determine the effects of multiple environmental and c

Growth of Chlorella vulgaris was characterized as a function of irradiance in a laboratory turbidostat (1L) and compared to batch growth in sunlit modules (5-25L) of the commercial NOVAgreen photobioreactor. The effects of variable sunlight and cultu

In times of dwindling petroleum reserves, microalgae may pose an alternate energy resource. Their growth is vast under favorable conditions. However, producing microalgae for energy in an economically as well as ecologically feasible way is a difficu

There is overwhelming evidence that microalgae would be the logical source of oils for biodiesel production, the best option for CO2 sequestration and numerous other applications. However, this apparent lucrative approach is still in its infancy. In

A commercial scale Spirulina algal biotechnology production plant was built at Musina, Limpopo Province, South Africa. Worldwide, the dietary supplement industry is extremely lucrative and, for this reason, Spirulina was chosen as the candidate organ

Some 1,370 W m−2 of light energy reaches the outer atmosphere of earth and on average only 240 W m−2 reaches the earth’s surface. Only a fraction of this is used to fix CO2 through photosynthesis, and efficiencies ranging from 0.1−8% for tota

Until recently, most large commercial scale microalgal production systems employed open systems. However, several large-scale closed systems have now been built and, for the first time, actual comparisons can be made. There are major operational diff

At least six important factors that determine productivity in mass algal cultures have been identified. These are (1) the culture depth or optical cross section, (2) turbulence, (3) nutrient content and supply, (4) cultivation procedure, (5) biomass
