Analysis of microbial community composition in a lab‐scale membrane distillation bioreactor

Abstract: AimsMembrane distillation bioreactors (MDBR) have potential for industrial applications where wastewater is hot or waste heat is available, but the role of micro-organisms in MDBRs has never been determined, and thus was the purpose of this study.Methods and ResultsMicrobial communities were characterized by bacterial and archaeal 16S and eukaryotic 18S rRNA gene tag-encoded pyrosequencing of DNA obtained from sludge. Taxonomy-independent analysis revealed that bacterial communities had a relatively low richne… Show more

“…This approach has been applied in ecological studies as an estimate of biodiversity, accounting for the number of different taxa as well as their relative abundance [ 11 ]. For the monitored thermophilic biogas plant, a Shannon index value of 2.55 was computed, which is slightly lower compared to values previously reported in studies analyzing mesophilic biogas digesters [ 56 , 57 ]. However, limited biodiversity under thermophilic conditions is a commonly observed phenomenon [ 58 , 59 ].…”

“…The Anoxybacillus sp. has been identified as a major bacterial genus in MD bioreactor suspended sludge [99]. Biofouling situations in PVDF MD membranes were studied in the feed side at temperatures of 47 o C (temperature below the optimum temperature for thermophilic bacterial growth), 55 o C (optimum temperature for thermophilic bacterial growth) and 65 o C (temperature above the optimum temperature for thermophilic bacterial growth) [98].…”

“…MDBR has the potential to be applied for wastewater reclamation in 'one step' and has more benefits (high quality effluent and low greenhouse gases emission) compared to the combined MBR and RO process. On the other hand, studies were conducted by Zhang, et al [50] to analyze the performances and microbial community composition on a lab-scale MDBR.…”
