An integrated approach for treatment and biomass resource recovery from juice industry wastewater using purple non-sulfur bacteria

Abstract. This study aims to treat juice industry wastewater and recover resources using purple non-sulfur bacteria (PNSB). Simulated was prepared used as a feedstock for PNSB. Carbon sources, including sucrose, fructose, glucose, tris-Na-citrate, were added different bottles separately inoculated with mixed culture of Tris-Na-citrate showed higher growth biomass production (650±70 mg/L) than the other carbon sources. The PNSB associated pH change; tris-Na-citrate change behavior i.e., it lesser decrease in medium others. effect substrate (using glucose) concentration on determined following experiment. A 400 mg/L (as COD) highest growth, whereas 800 returned (776±1 mg/L). Total organic removal (TOC) increased an increase concentration. Inorganic initially decreased but then over period; however, also directly correlated initial Lastly, TOC, IC, COD investigated. 6.0 or above (up 8.0) required remove inorganic carbon.
