Organic Carbon Is Ineffective in Enhancing the Growth of Dunaliella

(1) Background: Mixotrophic growth is commonly associated with higher biomass productivity and lower energy consumption. This paper evaluates the impact of using different carbon sources on growth, protein profile, nutrient uptake for Dunaliella tertiolecta CCAP 19/30 to assess potential mixotrophic growth. (2) Methods: Two experimental sets were conducted. The first assessed contribution atmospheric D. microalgae capacity grow heterotrophically an organic source provide both energy. second set evaluated its yield quality. (3) Results: could not heterotrophically. Cell optical density, ash-free dry weight, essential amino acids index inferior all treatments compared NaHCO3. Neither cell nor density presented significant differences among containing carbon, demonstrating that does boost All similar nitrogen, phosphorus, sulfur recovery, relative carbohydrate content. (4) Conclusions: Based results this paper, obligated autotroph cannot mixotrophically carbon.
