Anaerobic fermentation is a widely used technology for resource recovery from municipal sludge (e.g., primary sludge). Micro-aeration is an emerging strategy which can be incorporated into this technology. However, the effect of micro-aeration on the anaer ...
In recent years, the recovery of valuable compounds from food waste like grape pomace is an emerging issue in the food sector. Grape pomace or marc can be considered as an important solid waste that is produced from the wine industries after the pressing a ...
Many challenges are faced in the conversion of biomass into advanced biofuels, one of which is finding the correct organism for the job. The filamentous fungus Aspergillus niger has been chosen as a biocatalyst for cellulose, hemicellulose, and lignin degr ...
Process stability is a key operational issue when operating dark fermentation with mixed microbial cultures for hydrogen production. This study aimed at mitigating the instability of hydrogen production by separately adding exogenous pure strains suspected ...

The production of volatile fatty acids (VFAs) represents a relevant option to valorize municipal wastewater (MWW). In this context, different capture technologies can be used to recover organic carbon from wastewater in form of solids, while pre-treatment ...
The development of biorefineries directed to the production of fuels, chemicals, and energy is important to reduce economic dependence and environmental impacts of a petroleum‐based economy. The last two decades have witnessed a fast industrialization and ...
Arsenic (As) is simultaneously a ubiquitous and a toxic element. Arsenic is subject to bio-transformations catalyzed by microorganisms constituting the As biogeochemical cycle. The primordial Earth was devoid of oxygen, exposing life to the highly mobile a ...
Purple non-sulfur bacteria (PNSB) are phototrophic organisms that have raised interest for both industrial and domestic wastewater treatment and valorization because of their very high assimilation (~1 g CODX g-1 COD substrate) and valuable compounds produ ...

Biofuels are considered sustainable and renewable alternatives to conventional fossil fuels. Biobutanol has recently emerged as an attractive option compared to bioethanol and biodiesel, but a significant challenge in its production lies in the separation ...
Iron is essential for most living organisms. In addition, its biogeochemical cycling influences important processes in the geosphere (e.g., the mobilization or immobilization of trace elements and contaminants). The reduction of Fe(III) to Fe(II) can be ca ...
