Abstract

Abstract:

In this study, the operation principle, structure and feature of simulated microgravity reactor were introduced mainly. Spirulinas platensis were cultured in phototrophic batches in three kinds of culture devices. The results showed that the simulated microgravity reactor (clinostat) for Spirulinas platensis culture is better than shake flask and fermenter light bioreactor, and its optimum conditions are as following: inoculation concentration 10%, illumination 4000 lx, 25 ℃ and culture time 9 days. By this way, the production of Spirulina platensis (dw) is 0.91 g/L, which is 2.41 times as much as that by large-scale culture and the Spirulina platensis trichomes cultured in the simulated microgravity reactor have good cell morphology.

Key words: Spirulina platensis, weightlessness simulation, phototrophic batch culture, clinostat
