The Effect of Light on the Growth and Product Accumulation of Chlorella

Abstract:

Microalgae are microscopic heterotrophicautotrophic photosynthesizing organisms with enormous potential as a source of biofuel. In the masses of biomasses, microalgae has the advantages of high lipid, large biomass, short growth cycle and easy cultivation and with microalgae as the raw material. Light condition is crucial to cultivation of microalgae.In this paper, the microalgae strain of Chlorella sp. was supplied in BG11 medium, and Cultivation optimization were experimented. The results were showed that growth of chlorella was associated with a saturated light intensity, light intensity which was suitable for the growth of chlorella was 2000Lux. Growth of chlorella required an appropriate light-dark alternation to facilitate matching of photoreaction of photosynthetic process with dark reaction of photosynthetic, appropriate light-dark photoperiod of illumination time which was suitable for the growth of chlorella was 12:12.
