Effect of photo, hetero and mixotrophic conditions on the growth and composition of Anabaena variabilis: An Energy Nexus approach

In the present study, three conditions of photoautotrophic (Case 1), heterotrophic (Case 2), and mixotrophic (Case 3) on the microalgal growth, lipid accumulation, and content of chlorophyll a and phycocyanin pigment in Anabaena vaginicola ISC90 have been investigated. Results shown that the specifi...
