This work aims at selecting a suitable strategy to accelerate the start-up of the anaerobic treatment of olive mill wastewater (OMW) and to enhance the biogas production. Two anaerobic sludges were tested in toxicity and biodegradability batch experiments: biomass acclimated to oleate (BAO) and biomass non-acclimated (BNA). The results showed that the resistance to OMW toxicity was higher for t...

(14)C-sulfamethoxazole biotransformation, sorption and mineralization was studied with heterotrophic and autotrophic biomass under aerobic and anoxic conditions, as well as with anaerobic biomass. The (14)C-radiolabelled residues distribution in the solid, liquid and gas phases was closely monitored along a total incubation time of 190 h. Biotransformation was the main removal mechanism, minera...

In the full-scale the anaerobic co-digestion of brewery yeast using granular biomass was studied. Full-scale operation with 0.7 % yeast concentration showed a 38.5 % increase in the biogas production and a 26.2 % increase in the organic loading rate, which resulted in an increase of the biomethane/natural-gas substitute ratio from 10 % to 16 %.

Employ system modeling to optimize SOFC system • configurations. Extend mode...

we evaluated the efficacy of a full-scale combined biophysicochemical system for treatingmolasses-based bioethanol wastewater in terms of organic substances, nutrient, and dark brown color removal. the main organic removal unit, i.e., the upflow anaerobic sludge blanket (uasb) reactor, achieved 80.7% removal and 4.3 nm3 methane production per cubic meter of wastewater with a hydraulic retention...

A new Firmicutes isolate, strain HV4-6-A5C, was obtained from the hydrolysis stage of a mesophilic and anaerobic two-stage lab-scale leach-bed system for biomethanation of fresh grass. It is assumed that the bacterial isolate contributes to plant biomass degradation. Here, we report a draft annotated genome sequence of this organism.

Biogeochemical processes mediated by microorganisms in river sediments (hyporheic sediments) play a key role in river metabolism. Because biogeochemical reactions in the hyporheic zone are often limited to the top few decimetres of sediments below the water-sediment interface, slow filtration columns were used in the present study to quantify biogeochemical processes (uptakes of O2, DOC, and ni...

anaerobic digestion is the breakdown of biodegradable organic material by microorganisms in the absence of oxygen or in an oxygen-starved environment.this technology is superior to the landfilling and also the aerobic composting. the aim of the present study was to examine whether the effluent volatile fatty acids from the anaerobic acidogenesis of the food waste can be used du to its high valu...
