Abstract:
One of the potential bio-degradable plastics is Polyhydroxyalkanoates (PHAs). The initial substrates to produce PHAs are mostly organic acids which could be found in many organic wastewaters. These can be used by mixed microbial culture to produce PHAs. The main purpose of using these waste streams as sole substrates is to effectively reduce the production cost of PHAs. However, it is necessary to degrade large molecules of carbon sources into useful organic acids by acidification pre-treatment. In this study, the ratios of the effluent from sucrose and molasses waste acidification fermenters were set at the ratios of 1:0, 1:1, 3:1, 1:3 resulting the produced PHAs concentrations of 18.33%, 24.21%, 26.88% and 32.48%, respectively.
