Efficient Production of 𝑛-Caproate From Syngas by a Co-culture of Clostridium Aceticum and Clostridium Kluyveri
(Elsevier, 2021-10-25)
[Abstract] In recent years, the possibility of merging technologies for waste recovery such as those based on syngas fermentation and chain elongation has been studied for the production of medium chain fatty acids (MCFAs) ...
Co-digestion of Cheese Whey With Sewage Sludge for Caproic Acid Production: Role of Microbiome and Polyhydroxyalkanoates Potential Production
(Elsevier, 2021-06-08)
[Abstract] The main aim of this work was to evaluate the efficiency of producing caproic acid and other volatile fatty acids using a co-digestion between cheese whey and sewage sludge in a continuous reactor. The effect ...
Carbon Dioxide Bioconversion Into Single Cell Oils (Lipids) In Two Reactors Inoculated With Acetobacterium Woodii and Rhodosporidium Toruloides
(Elsevier, 2021-08-12)
[Abstract] Acetobacterium woodii was able to produce high concentrations of acetic acid, i.e., > 20 g/L, from CO2, in the presence of H2 as an energy source, which was favoured by maintaining a near-optimal pH of 7.8 in ...
Autotrophic (C₁-Gas) Versus Heterotrophic (Fructose) Accumulation of Acetic Acid and Ethanol in Clostridium Aceticum
(Elsevier, 2021-07-03)
[Abstract] The influence of the carbon source on the metabolism and growth of Clostridium aceticum was investigated, supplying either CO or fructose as sole carbon source. The acid and solvent production patterns were ...
Treatment of waste gas contaminated with dichloromethane using photocatalytic oxidation, biodegradation and their combinations
(Elsevier, 2020-08-22)
[Abstract] The treatment of waste gas (WG) containing dichloromethane (DCM) using advanced oxidation processes (AOPs) [UV and UV-TiO2], biological treatment (BT), and their combination (AOPs-BT) was tested. AOP tests were ...
Design of Low-Cost Ethanol Production Medium From Syngas: An Optimization of Trace Metals for Clostridium Ljungdahlii
(MDPI, 2021-10-25)
[Abstract] Syngas fermentation via the Wood-Ljungdahl (WL) pathway is a promising approach for converting gaseous pollutants (CO and CO2) into high-value commodities. Because the WL involves several enzymes with trace metal ...
Selective Butanol Production From Carbon Monoxide by an Enriched Anaerobic Culture
(Elsevier, 2021-09-25)
[Abstract] An anaerobic mixed culture able to grow on pure carbon monoxide (CO) as well as syngas (CO, CO2 and H2), that produced unusual high concentrations of butanol, was enriched in a bioreactor with intermittent CO ...
Reactor Designs and Configurations for Biological and Bioelectrochemical C1 Gas Conversion: A Review
(MDPI, 2021-11-07)
[Abstract] Microbial C1 gas conversion technologies have developed into a potentially promising technology for converting waste gases (CO2, CO) into chemicals, fuels, and other materials. However, the mass transfer constraint ...
Advances in the development of electrode materials for improving the reactor kinetics in microbial fuel cells
(Elsevier, 2021-12-07)
[Abstract] Microbial fuel cells (MFCs) are an emerging technology for converting organic waste into electricity, thus providing potential solution to energy crises along with eco-friendly wastewater treatment. The electrode ...
Influence of feedstock mix ratio on microbial dynamics during acidogenic fermentation for polyhydroxyalkanoates production
(Elsevier, 2021-12-01)
[Abstract] The nature of microbial populations plays an essential role in the production of volatile fatty acids (VFA) during acidogenesis, the first stage in polyhydroxyalkanoates (PHA) production using mixed cultures. ...
