Carbon supply is the major cost component in microalgal cultures. Aiming to enhance the dissolved inorganic carbon uptake efficiency in microalgal cultures, Spirulina sp LEB-18 was cultivated in mediums containing NaHCO3 concentrations ranging from 2.8 to 100 g L-1. Results indicated that lower dissolved inorganic carbon concentratios (2.8 g L-1 NaHCO3) produce higher growth parameters (Xmax = 0.75 g L-1; Pmax = 0.145 g L-1 d-1; µmax = 0.254 d-1) and lower carbon losses (13.61%). At 50 g L-1 of NaHCO3 cell growth was inhibited and carbon losses reached 38.73%.poropen accessCarbonMicroalgaSpirulina sp LEB-18articlehttp://dx.doi.org/10.1590/S0100-40422008000800022.
