Continuous production of selenomethionine-enriched Chlorella sorokiniana biomass in a photobioreactor
Original language description
This article describes the enrichment of the fresh-water green microalga C. sorokiniana in selenomethionine (SeMet). The microalga was cultivated in a 2.2 L glass-vessel photobioreactor, in a culture medium supplemented with selenate (SeO42-) concentrations ranging from 5 to 50 mg/L. Although selenate exposure lowered culture viability, C. sorokiniana grew well at all tested selenate concentrations, however cultures suplemented with 50 mg/L selenate did not remain stable at steady state. A suitable selenate concentration in fresh culture medium for continuous operation was determined, which allowed stable long-term cultivation at steady state and maximal SeMet productivity. In order to do that, the effect of dilution rate on biomass productivity, viability and SeMet content of C. sorokiniana at several selenate concentrations were determined in the photobioreactor. A maximal SeMet productivity of 0,021 mg/L/day was obtained with 40 mg/L selenate in the culture medium. Then a continuous
