Enhancement of Pigments Production by Nannochloropsis oculata Cells in Response to Bicarbonate Supply

In this study, the effects of bicarbonate addition on growth and pigment contents of the unicellular microalga Nannochloropsis oculata, were evaluated. N. oculata represents an interesting source of biomolecules widely used for food supplements and nutraceutical...
