The aim of this research was to evaluate the kinetic modeling of the substrate (chemical oxygen demand) limitation in heterotrophic microalgal cultures. The experiments were carried out in a bubble column bioreactor in batch mode at 30ºC, pH 8.0, absence of light, 1VVM and C/N ratio of 50. The limitation for chemical oxygen demand was investigated through of four models (Monod, Teissier, Moser, Contois). The Moser model was found to be sufficient to describe the substrate (COD) limitation, as evidenced by the statistical criteria. The predictions indicate maximum specific growth rate of 0.055h-1 and a saturation constant of 86.25mgCOD.L-1.
