1. Project description

Aerobic biological processes are widely applied for wastewater treatment. During the process, while improving the water quality, a (waste) surplus activated sludge is produced. It has been demonstrated in the pilot-scale that surplus activated sludge could accumulate carbon storage elements Polyhydroxyalkanoates (PHAs) up to 40%/ VSS. Surplus activated sludge is a complex mixed culture biomass. In surplus activated sludge, only limited information about the PHA accumulation microorganisms is known. The objective of this project is to gain a deepened insight into the identification of the PHA accumulators and understand the distribution of intracellular PHA granular among different microorganisms. The techniques such as Next Generation Sequencing, Fluorescence In-situ Hybridization, and PHA granular staining would be investigated and applied. This project is embedded in the theme ‘Biopolymers from water’ (https://www.wetsus.nl/biopolymers-from-water ) in collaboration with Delft University and industrial partners.
