Special Issue Information

Dear Colleagues,

The aim of this Special Issue is to present the most recent advances in membrane bioreactor (MBR) technology in the area of resource recovery. As a technology that unites the advantages of biological conversion, separation, purification, and concentration, MBRs enjoy great research and industrial attention in bioprocesses from wastewater treatment to waste biorefineries. Considering the growing role of MBRs in enhancing sustainability and resource recovery in bioprocesses to further comply with the circular economy concept, it is in our best interest to provide a platform to gather all recent advances in the broad scope of MBR application in resource recovery and invite you submit articles, case studies, reviews, and communications considering the following keywords

Volatile fatty acids (VFAs) appear to be an economical carbon feedstock for the cost-effective production of polyhydroxyalkanoates (PHAs). The use of VFAs, however, could impose a drawback of substrate inhibition at high concentrations, resulting in low microbial PHA productivity in batch cultivations. In this regard, retaining high cell density using immersed membrane bioreactor (iMBR) in a (semi-) continuous process could enhance production yields. In this study, an iMBR with a flat-sheet membrane was applied for semi-continuous cultivation and recovery of Cupriavidus necator in a bench-scale bioreactor using VFAs as the sole carbon source. The cultivation was prolonged up to 128 h under an interval feed of 5 g/L VFAs at a dilution rate of 0.15 (d−1), yielding a maximum biomass and PHA production of 6.6 and 2.8 g/L, respectively. Potato liquor and apple pomace-based VFAs with a total concentration of 8.8 g/L were also successfully used in the iMBR, rendering the highest PHA content of 1.3 g/L after 128 h of cultivation. The PHAs obtained from both synthetic and real VFA effluents were affirmed to be poly(3-hydroxybutyrate-co-3-hydroxyvalerate) with a crystallinity degree of 23.8 and 9.6%, respectively. The application of iMBR could open an opportunity for semi-continuous production of PHA, increasing the feasibility of upscaling PHA production using waste-based VFAs. Full article
