[CEST2019_00281] Production of PHAs with enhanced properties from sugar-based wastewater in a two stage process
by Fouskakis G., Stergiopoulou E., Alexandropoulou M., Antonopoulou G., Ntaikou I., Lyberatos G.
The experimental design of the study was based on two different microbial processes, i.e. anaerobic fermentation of a sugar-based wastewater via mixed acidogenic cultures and aerobic polymerization of the produced acids and alcohols for poly-hydroxy-alkanoates (PHAs) production, via enriched cultures. For the first stage of the combined process, a continuous up-flow column reactor (UFCR) and a continuous stirred tank reactor (CSTR) were developed. For the optimization of the performance of both reactors, the effect of main parameters influencing the distribution of the produced acids was investigated. The liquid effluents of the reactors, containing fatty acids and ethanol were forwarded to the second stage of the combined process. A sequential batch reactor (SBR) was used for the second, aerobic stage of PHAs production
