FIGURE 5.

Principal components analysis (PCA) based on the biochemical, nutritional, and functional characteristics, and inhibitory activity of wet (WB), dried at low temperature (DB), and lyophilized (LB) Spirulina biomass. All biomasses were also treated with Alcalase^® (A, 1% vol/wt), fermented with L. plantarum T0A10 (F, final cell density of circa 7 log10 cfu/g), or fermented and treated with Alcalase^® (AF). Enzymatic and microbial treatments were carried out at 30°C for 24 h. Prot, protein concentration; Pep, peptide concentration; AA, amino acid concentration; IVPD, in vitro protein digestibility; Aox_ABTS, antioxidant activity of biomasses on ABTS radical; A_bacter, antibacterial activity; A_fung, antifungal activity.
