    • Carboxylic acids production and electrosynthetic microbial community evolution under different CO2 feeding regimes 

      Dessì, Paolo; Sánchez, Carlos; Mills, Simon; Cocco, Francesco Giuseppe; Isipato, Marco; Ijaz, Umer Z.; Collins, Gavin; Lens, Piet N.L. (Elsevier, 2020-10-15)
      Microbial electrosynthesis (MES) is a potential technology for CO2 recycling, but insufficient information is available on the microbial interactions underpinning electrochemically-assisted reactions. In this study, a MES ...

    • The dairy biorefinery: Integrating treatment processes for cheese whey valorisation 

      Asunis, Fabiano; De Gioannis, Giorgia; Dessì, Paolo; Isipato, Marco; Lens, Piet N.L.; Muntoni, Aldo; Polettini, Alessandra; Pomi, Raffaella; Rossi, Andreina; Spiga, Daniela (Elsevier, 2020-08-28)
      With an estimated worldwide production of 190 billion kg per year, and due to its high organic load, cheese whey represents a huge opportunity for bioenergy and biochemicals production. Several physical, chemical and ...

    • Fermentative hydrogen production from cheese whey with in-line, concentration gradient-driven butyric acid extraction 

      Dessì P, Asunis F, Ravishankar H, Cocco FG, De Gioannis G, Muntoni A, Lens PNL; Dessì, Paolo; Asunis, Fabiano; Ravishankar, Harish; Cocco, Francesco Giuseppe; De Gioannis, Giorgia; Muntoni, Aldo; Lens, Piet N.L. (Elsevier, 2020-08-01)
      Hydrogen (H2) generation from cheese whey with simultaneous production and extraction of volatile fatty acids (VFAs) was studied in UASB reactors at two temperatures (20 and 35 °C) and pH values (5.0 and 4.5). The extraction ...

    • Microbial electrochemical technologies: Electronic circuitry and characterization tools 

      Sánchez, Carlos; Dessì, Paolo; Duffy, Maeve; Lens, Piet N.L. (Elsevier, 2019-11-16)
      Microbial electrochemistry merges microbiology, electrochemistry and electronics to provide a set of technologies for environmental engineering applications. Understanding the electronic concepts is crucial for effectively ...

    • Microbial electrosynthesis: Towards sustainable biorefineries for production of green chemicals from CO2 emissions 

      Dessì, Paolo; Rovira-Alsina, Laura; Sánchez, Carlos; Dinesh, G. Kumaravel; Tong, Wenming; Chatterjee, Pritha; edesco, MicheleT; Farràs, Pau; Hamelers, Hubertus M.V.; Puig, Sebastià (Elsevier, 2020-12-01)
      Decarbonisation of the economy has become a priority at the global level, and the resulting legislative pressure is pushing the chemical and energy industries away from fossil fuels. Microbial electrosynthesis (MES) has ...

    • OpenTCC: An open source low-cost temperature-control chamber 

      Sánchez, Carlos; Dessì, Paolo; Duffy, Maeve; Lens, Piet N.L. (Elsevier, 2020-02-24)
      Microbial electrochemical technologies (MET) are emerging systems for environmental applications such as renewable energy production or pollution remediation. MET research often requires stable temperatures and low levels ...

    • Organic waste biorefineries: Looking towards implementation 

      Alibardi, Luca; Astrup, Thomas F.; Asunis, Fabiano; Clarke, William P.; De Gioannis, Giorgia; Dessì, Paolo; Lens, Piet N.L.; Lavagnolo, Maria Cristina; Lombardi, Lidia; Muntoni, Aldo; Pivato, Alberto; Polettini, Alessandra; Pomi, Raffaella; Rossi, Andreina; Spagni, Alessandro; Spiga, Daniela (Elsevier, 2020-07-16)
      The concept of biorefinery expands the possibilities to extract value from organic matter in form of either bespoke crops or organic waste. The viability of biorefinery schemes depends on the recovery of higher-value ...

    • Propionate production by bioelectrochemically-assisted lactate fermentation and simultaneous CO2 recycling 

      Isipato, Marco; Dessì, Paolo; Sánchez, Carlos; Mills, Simon; Ijaz, Umer Z.; Asunis, Fabiano; Spiga, Daniela; De Gioannis, Giorgia; Mascia, Michele; Collins, Gavin; Muntoni, Aldo; Lens, Piet N. L. (Frontiers Media, 2020-12-15)
      Production of volatile fatty acids (VFAs), fundamental building blocks for the chemical industry, depends on fossil fuels but organic waste is an emerging alternative substrate. Lactate produced from sugar-containing waste ...
