GROWTH OF HAEMATOCOCCUS-LACUSTRIS - A CONTRIBUTION TO KINETIC MODELING

The results of studies with the microalga Haematococcus lacustris, gro wn under heterotrophic, autotrophic and mixotrophic conditions, were e mployed to fit kinetic parameters such as specific growth rate, linear growth rate and acetate consumption as a function of irradiance and a cetate concentration. Growth was inhibited at the highest light intens ities used, as was acetate uptake. The specific growth rate in mixotro phic conditions was obtained by the addition of autotrophic and hetero trophic components which were affected by a variable inhibition term d epending on irradiance level and acetate concentration.
