Abstract

The availability of agricultural wastewater in arid climes limits the possibility of exploiting purple non-sulfur bacteria (PNSB) to recover aqua-feed bioproducts. Thus, this study examines the feasibility of recovering such bioproducts using fuel-synthesis process water (FSPW) as a feedstock. Experiments were performed under varying light conditions. The results revealed that PNSB cultured in the zero-nitrogen feedstock had over 40 % protein content, contained substantial lipids and pigments, and reduced FSPW organics by over 70 %. The light intensity significantly impacted biomass constituents and treatment efficiency. The results are promising for the potential development of a circular economy to convert FSPW to aqua-feed.
