The objective of this study was to examine the applicability of mixed cultures for 1,3-propanediol (1,3-PDO) production from crude glycerol. Three different sources of mixed cultures were tested, where the mixed culture from a municipal wastewater treatment plant showed the best results. 1,3-PDO can be produced as the main product in this mixed culture with typical organic acids like acetic and butyric acids as by-products. The yield was in the range of 0.56-0.76 mol 1,3-PDO per mol glycerol… CONTINUE READING
