Abstract

Aims Arthrospira platensis has been studied for single-cell protein production because of its biomass composition and its ability of growing in alternative media. This work evaluated the effects of different dilution rates (D) and urea concentrations (N(0)) on A. platensis continuous culture, in terms of growth, kinetic parameters, biomass composition and nitrogen removal. Methods and results Arthrospira platensis was continuously cultivated in a glass-made vertical column photobioreactor agitated with Rushton turbines. There were used different dilution rates (0·04-0·44 day(-1)) and urea concentrations (0·5 and 5 mmol l(-1)). With N(0) = 5 mmol l(-1), the maximum steady-state biomass concentration was 1415 mg l(-1), achieved with D = 0·04 day(-1), but the highest protein content (71·9%) was obtained by applying D = 0·12 day(-1), attaining a protein productivity of 106·41 mg l(-1) day(-1). Nitrogen removal reached 99% on steady-state conditions. Conclusions The best results were achieved by applying N(0) = 5 mmol l(-1); however, urea led to inhibitory conditions at D ≥ 0·16 day(-1), inducing the system wash-out. The agitation afforded satisfactory mixture and did not harm the trichomes structure. Significance and impact of the study These results can enhance the basis for the continuous removal of nitrogenous wastewater pollutants using cyanobacteria, with an easily assembled photobioreactor.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
