| Abstract: | In order to establish monoalgae cultivation system of Spinulina platensis dominantly in the illuminant panel photobioreactor, the pH adjustment effect of the algal suspension on the culture of Spinulina platensis was studied. The experimental results show that the pH not only influences the ionic dissociation of inorganic carbon source and the photosynthetic oxygen evolution, but also is the key factor to control monoalgae culture of Spinulina platensis in the photobioreactor. If the pH value of the algal suspension was controlled at the range of 9.6, even growing in the worse condition such as lower temperature of 15℃ and nutrients limited, Spinulina platensis still can keep preponderant monoalgae in the photobioreactor. |
