摘要
A tubular photobioreactor was constructed with glass tubing of 5 4mm bore. The high density culture of Spirulina platensis was tested and the biomass concentration had gained up to 12 4g/L. The research shows the photobioreactor productivity can be influenced significantly by incident light intensity and light/dark ratio. Along with the increasing of light/dark ratio, the productivity per culture volume increased at first, then the light/dark ratio saturation phenomenon occurred; and the productivity per illuminated area increased at first, after that it decreased. There is an optimum light/dark ratio, at which the productivity per illuminated area is optimized. The dynamic viscosity measurement of the culture liquid shows non Newtonian behavior and it can be described by power law equation.
