Oct 2022 | Fluid-like bed bioreactors have shown their usefulness in recovering nutrients as PPB biomass, favoring planktonic growth, and thus facilitating the recovery of a valuable product: the biomass of PPB.
Purple phototrophic bacteria (PPB), the most versatile microorganisms on earth, are highly effective for sustainable wastewater treatment and nutrient recovery as cell protein. Now we can exert fine tuning of their metabolism by using fluid-like electrodes, a technology developed at Bioe Group. We have enhanced the rate for degrading pollutants in brewery wastewater while avoiding emissions of greenhouse gases such as methane and, eventually, generating single cell protein from brewery nutrients.
