Resource recovery from saline waste sludge through the combined use of acid fermentation and anaerobic digestion KU Leuven
The overall aim of the project is to develop an approach to maximize the potential of mixed-culture fermentation for high value compounds from saline waste sludge. The following subobjectives are defined: (i) analyzing the effect of pH on VFA production from saline waste sludge; (ii) promoting hydrogen production from saline waste sludge with the use of TB and APG; (iii) evaluating the feasibility and economic benefits of the effluent as ...
DeLock - DEnitrification unLOCKed. Unlocking the N2O-reduction capacity of denitrifying microbial communities to combat N2O emissions during wastewater treatment processes. Ghent University
In the era of global warming, solutions to reduce greenhouse gases emissions are urgently needed. Nitrous oxide (N2O) has a global warming potential almost 300 times the one of CO2, and accounts for 8% of total anthropogenic GHG emissions. The majority
Adhesins: The missing link for activated sludge bioflocculation KU Leuven
Activated sludge bioaggregation is critical to the proper performance of biological wastewater treatment systems because without an efficient sludge-water separation, the effluent quality deteriorates, and slow-growing organisms might wash out. Activated sludge flocs are mainly composed of floc-forming and filamentous bacteria and extracellular polymeric substances. Among the extracellular polymeric substances are the amyloid adhesins: highly ...
Adaptation of enterobacteria to growth at low pH: mechanisms and relevance for food safety. KU Leuven
The Enterobacteriaceae family comprises several important foodborne pathogens and spoilage bacteria. To pass successfully through the food production chain, these bacteria have to endure a wide spectrum of stresses, such as cold, heat, desiccation, acid, or oxidative stress. Acid stress, in particular, exists in the form of the natural acidity of some food products, organic acids formed in fermented foods or added as a food acidulant ...
