The role of carbon source in the nitrogen assimilation by purple phototrophic bacteria: Implication in resources recovery from domestic wastewater.

Resources from wastewater treatment process are currently underutilised. Resources recovery from wastewater could be the solution to water security and protein for livestock agriculture. In this study, the effects of different carbon sources and nitrogen concentrations on nutrient removal, amino acid biosynthesis, and nitrogen regulation, in purple phototrophic bacteria mixed culture were evaluated. The outcomes of this thesis resulted in: i) a more sustainable and viable wastewater treatment process, ii) the development of a more sustainable source of protein for livestock agriculture, and iii) a better understanding in the nitrogen regulation of mixed culture community.
