Efficient pH and dissolved CO₂ conditions for indoor and outdoor cultures of green alga Parachlorella.

ABSTRACT: Efficient pH and dissolved CO₂ conditions for indoor (50-450 mL scale) and outdoor (100-500 L scale) culture of a green alga BX1.5 strain that can produce useful intracellular lipids and extracellular polysaccharides were investigated for the first time in Parachlorella sp. The cultures harvested under 26 different conditions were analysed for pH, dissolved CO₂ concentration, and the biomass of extracellular polysaccharides. The BX1.5 strain could thrive in a wide range of initial medium pH ranging from 3 to 11 and produced valuable lipids such as C16:0, C18:2, and C18:3 under indoor and outdoor culture conditions when supplied with 2.0% dissolved CO₂. Particularly, the acidic BG11 medium effectively increased the biomass of extracellular polysacchar
