Growth of oil accumulating microalga Neochloris oleoabundans under alkaline-saline conditions

► Oil accumulating microalgae cultivated under alkaline-saline conditions are a potential feedstock for biofuel production. ► Alkaline-saline media low concentrated in calcium and phosphate have minimum precipitation and still sustain algal growth. ► Lipid accumulation in microalgae is not only dependent on the nitrogen supply but also on the alkalinity of the medium.
