Notes: *based on gTSS rather than gTS adapted from Hülsen et al. (2018) **calculated (100-protein + fat + ash + moisture). ***Amino acids from PPB biomass grown on synthetic wastewater (WW) analysed by Symbio and from domestic wastewater by Ridley. ****Total carotenoids and Bchlorophyll analysed at UQ. TKN: total Kjeldahl nitrogen, TP: total phosphorous, PHB: polyhydroxybutyrate.
