A recycling culture system was introduced to maintain constant temperature for outdoor cultivation of Chlorella minutissima. A 14 ℓ photo-bioreactor was designed to recycle 35℃ warm media for outdoor long-term cultivation. For autotrophic cultivation, the media temperature was measured as 35℃, maintaining 1.60 (g-dry wt./L) of maximum biomass. This system was proved to maintain relatively constant temperature of 34℃ under fed-batch condition. However, for
batch cultivation, temperature was decreased down to 21℃. It seems that batch culture would not be feasible for outdoor long-term cultivation. The mixotrophic process maintained 11.5 (g-dry wt./L) of maximum cell growth with 27 (%, w/w) of total lipid under recycling culture system. Therefore, based on this result, we can expect this recycling culture system to be applied for long-term outdoor cultivation even in Korea where there is relatively low temperature season for
several months.
