Algal Lipids and Omega-3 Production via Autotrophic and Heterotrophic Pathways at Cellana?s Kona Demonstration Facility, Hawaii
- Cellana LLC
Cellana?s Kona Demonstration Facility (KDF) is a 2.5 hectare facility, with 17,000 sq. ft. under roof and 1 hectare of cultivation systems. KDF is designed to execute and support all stages of the production process at pilot scale, from cultivation through extraction. Since Feb. 2009, KDF has been producing up to 0.7MT dry weight of algal biomass per month, while at the same time optimizing processes of cultivation, harvesting, dewatering and extraction. The cultivation system at KDF uses ALDUO? technology, a hybrid system of photobioreactors (PBRs) and open ponds. All fluid transfers related to KDF cultivation and harvesting processes are operated and monitored by a remote Process-Control System. Fluid transfer data, together with biochemical data, enable the mass balance calculations necessary to measure productivity. This poster summarizes methods to improve both biomass and lipids yield by 1) alleviating light limitation in open ponds, 2) de-oxygenation and 3) heterotrophic lipid production for post-harvesting cultures.
