Abstract

The microalga Arthrospira platensis BEA 005B was produced using 80 m 2 (9 m 3) raceway photobioreactors achieving a biomass productivity of 28.2 g·m-2·day-1 when operating the reactors in semi-continuous mode (0.33 day-1). The produced biomass was rich in proteins (58.1 g·100 g-1) and carbohydrates (25.6 g·100 g-1); the content of phycocyanins and allophycocyanins was 115.4 and 36.9 mg·g-1, respectively. Ultrasounds and high-pressure homogenisation allowed recovering approximately 90% of the initial protein content of the biomass; however, the energetic requirements of the former (∼100 kJ·kg-1) were significantly lower than those of high-pressure homogenisation (∼200 kJ·kg-1). An in silico analysis revealed that papain and ficin would allow releasing a large number of bioactive peptides with antioxidant, antihypertensive (ACE-I and renin), and antidiabetic (DPP-IV, α-amylase, and α-glucosidase) properties. Both were assessed in vitro together with Alcalase and pepsin leading to the generation of enzymatic hydrolysates with in vitro bioactivity.

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.
