Bioreactor scalability: laboratory-scale bioreactor design influences performance, ecology, and community physiology in expanded granular sludge bed bioreactors
Connelly, Stephanie; Shin, Seung Gu; Dillon, Robert J.; Ijaz, Umer Zeeshan; Quince, Christopher; Sloan, William; Collins, Gavin (Frontiers Media, 2017)Studies investigating the feasibility of new, or improved, biotechnologies, such as wastewater treatment digesters, inevitably start with laboratory-scale trials. However, it is rarely determined whether laboratory-scale ... -
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 ... -
Effect of sulfate on low-temperature anaerobic digestion
Madden, Pádhraig; Al-Raei, Abdul M.; Enright, Anne M.; Chinalia, Fabio A.; de Beer, Dirk; O'Flaherty, Vincent; Collins, Gavin (Frontiers Media, 2014-07-24)The effect of sulfate addition on the stability of, and microbial community behavior in, low-temperature anaerobic expanded granular sludge bed-based bioreactors was investigated at 15 degrees C. Efficient bioreactor ... -
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 ...
