Abstract

Abstract The objective of this study was to integrate the treatment of aquaculture effluent with the biomass and macronutrients production by Spirulina sp. LEB 18. The first experiment was carried out in a photobioreactor (1 L) and the best biomass production condition was reproduced on a pilot scale in a raceway type bioreactor (5 L). The best treatment was T25 (100% of wastewater supplemented with 25% of Zarrouk nutrients). The biomass production in the raceway system (T25) was higher (3.33 g L−1) than the control (2.32 g L−1) and the carbohydrate (69.77%) and lipid (12.77%) were also higher. The content of carotenoids in T25 was significant (9.68 μg mL−1). Spirulina sp. LEB 18 removed phosphate (99.97%); COD (89.34%) and nitrate (81.10%) from aquaculture effluent. The effluent showed absence of heavy metals and concentration of Al; Fe; Ca and Mg higher than the control culture with Zarrouk nutrients. The Spirulina sp. LEB 18 can be applied as a bioremediation agent of aquaculture wastewater with high production of biomass, carbohydrate, lipid and carotenoid.

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.
