Phosphate (Pi) is an irreplaceable nutrient in all living organisms and is mined from Pi rock. Since the global Pi rock reserves will be depleted in a few hundred years, it is essential to develop new strategies for recycling Pi from unused Pi waste streams. One such Pi waste stream is plant biomass, a by-product of the deoiling of seeds and bran. In addition, unused Pi accumulates in various waste streams during the production of Pi rich molecules. In this thesis, Pi was recycled from these waste streams into polyphosphate (polyP). Therefore, Pi-starved Saccharomyces cerevisiae was subjected...
