Low-temperature anaerobic digestion is associated with differential methanogenic protein expression
(Oxford University Press, 2015-04-09)
Anaerobic digestion (AD) is an attractive wastewater treatment technology, leading to the generation of recoverable biofuel (methane). Most industrial AD applications, carry excessive heating costs, however, as AD reactors ...
Influence of stormflow and baseflow phosphorus pressures on stream ecology in agricultural catchments
(Elsevier, 2017-03-09)
Stormflow and baseflow phosphorus (P) concentrations and loads in rivers may exert different ecological pressures during different seasons. These pressures and subsequent impacts are important to disentangle in order to ...
Low-temperature (10°C) anaerobic digestion of dilute dairy wastewater in an EGSB bioreactor: microbial community structure, population dynamics, and kinetics of methanogenic populations
(Hindawi Publishing Corporation, 2013-07-25)
The feasibility of anaerobic digestion of dairy wastewater at 10 degrees C was investigated in a high height : diameter ratio EGSB reactor. Stable performance was observed at an applied organic loading rate (OLR) of 0.5-2 ...
Biological phosphorus removal during high-rate, low-temperature, anaerobic digestion of wastewater
(Frontiers Media, 2016-03-03)
We report, for the first time, extensive biologically mediated phosphate removal from wastewater during high-rate anaerobic digestion (AD). A hybrid sludge bed/fixed-film (packed pumice stone) reactor was employed for ...
Functional responses and adaptation of mesophilic microbial communities to psychrophilic anaerobic digestion
(Oxford University Press, 2015-10-27)
Psychrophilic (<20°C) anaerobic digestion (AD) represents an attractive alternative to mesophilic wastewater treatment. In order to investigate the AD microbiome response to temperature change, with particular emphasis on ...
In vitro comparative cytotoxicity study of a novel biocidal iodo-thiocyanate complex
(Elsevier, 2018-04-03)
Novel biocides, which avoid the induction of cross-resistance to antibiotics, are an urgent societal requirement. Here, we compared the cytotoxic and bactericidal effects of a new antimicrobial agent, the iodo-thiocyanate ...
Cold adaptation and replicable microbial community development during long-term low-temperature anaerobic digestion treatment of synthetic sewage
(Oxford University Press, 2018-05-25)
The development and activity of a cold-adapting microbial community was monitored during low-temperature anaerobic digestion (LtAD) treatment of wastewater. Two replicate hybrid anaerobic sludge bed-fixed-film reactors ...
Effect of sulfate on low-temperature anaerobic digestion
(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 ...
Antibacterial potential of an antimicrobial agent inspired by peroxidase-catalyzed systems
(Frontiers Media, 2017-05-02)
Antibiotic resistance is an increasingly serious threat to global health. Consequently, the development of non-antibiotic based therapies and disinfectants, which avoid induction of resistance, or cross-resistance, is of ...
Agricultural anaerobic digestion power plants in Ireland and Germany: policy and practice
(Wiley, 2016-08-24)
The process of anaerobic digestion (AD) is valued as a carbon-neutral energy source, while simultaneously treating organic waste, making it safer for disposal or use as a fertilizer on agricultural land. The AD process in ...
