  Target the Enhancement of DIET-Based CO - ACS Publications

  2024222 · In anaerobic systems, CO2-dependent methanogens as terminal electron acceptors determine the feasibility of organic degradation. In this study, targeting the enhancement of CO2-dependent methanogenesis, a strategy coupling the addition of magnetite and inorganic carbon recirculation was proposed. The results showed that the …

  Stimulation of Smithella‐dominating propionate oxidation in …

  2019318 · Here, we evaluate the effects of nanoscale magnetite (nanoFe 3 O 4) and multiwalled CNTs on the syntrophic oxidation of propionate in an enrichment obtained from lake sediment. The microbial populations were composed mainly of Smithella , Syntrophomonas , Methanosaeta, Methanosarcina and Methanoregula .

  Sequential particle-size and magnetic separation for enrichment of …

  202021 · Abstract Coal fly ash is known to contain rare-earth elements and yttrium (REY). In this research, three Indonesian coal fly ashes were characterized and subjected to sequential physical separation processes. The characterization results showed that the ashes had a critical REY content exceeding 38 % and outlook coefficient ( Coutlook) of …
