Converting Fuel‐Synthesis Process Water to Aquaculture Feed by Purple Non‐Sulfur Bacteria

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