AWMC Seminar Program: Purple phototrophic bacteria – a protein rich product from wastewater?

Purple phototrophic bacteria – a protein rich product from wastewater?

Abstract: Purple phototrophic bacteria (PPB) have been proposed as a wastewater treatment platform for simultaneous and non-destructive organics and nutrients removal. The proof-of-concept on domestic wastewater has been expanded towards agri-industrial applications and the treatment capacities as well as the recovery potentials have been assessed. For this purpose, several batch tests were conducted on a variety of wastewaters and a continuous lab-scale photo bioreactor was operated for 250 d treating poultry processing effluent.  The results show partitioning of soluble components (COD, NH4-N and PO4-P)  into the biomass and due to non-destructive removal and high yields the high recovery potentials are much higher compared to conventional treatment. This is of particular interest when analysing the PPB biomass which is generally characterised by high protein (>60% DW) and amino acid content which is likely suitable as feed or feed additive. This presentation will summarise the latest results in terms of wastewater treatment and nutrient recovery as well as the potential value proposition of wastewater treatment with purple phototrophic bacteria and the generation of a protein rich product.
