From: Optimized inorganic carbon regime for enhanced growth and lipid accumulation in Chlorella vulgaris
pH for cultures of C. vulgaris re-suspended into medium depleted of nitrogen and supplemented with various bicarbonate salts. Final concentrations of bicarbonate salts per experimental condition: 0 mM HCO3 − (control), 50 mM ACS grade NaHCO3 (grade 1), 50 mM industrial grade NaHCO3 (grade 2), 50 mM KHCO3, 50 mM NH4HCO3, 50 mM Na2CO3, and 25 mM NaHCO3∙Na2CO3 (25 mM of sesquicarbonate was used to provide equimolar carbon) (n = 3)
