Investigation of biomass and lipids production with Neochloris oleoabundans in photobioreactor
چکیده انگلیسی

The fresh water microalga Neochlorisoleoabundans was investigated for its ability to accumulate lipids and especially triacylglycerols (TAG). A systematic study was conducted, from the determination of the growth medium to its characterization in an airlift photobioreactor. Without nutrient limitation, a maximal biomass areal productivity of 16.5 g m−2 day−1 was found. Effects of nitrogen starvation to induce lipids accumulation was next investigated. Due to initial N.oleoabundans total lipids high content (23% of dry weight), highest productivity was obtained without mineral limitation with a maximal total lipids productivity of 3.8 g m−2 day−1. Regarding TAG, an almost similar productivity was found whatever the protocol was: continuous production without mineral limitation (0.5 g m−2 day−1) or batch production with either sudden or progressive nitrogen deprivation (0.7 g m−2 day−1). The decrease in growth rate reduces the benefit of the important lipids and TAG accumulation as obtained in nitrogen starvation (37% and 18% of dry weight, respectively).
