Abstract
AbstractThe 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.
