Effect of electron acceptors on product selectivity and carbon flux in carbon chain elongation with Megasphaera hexanoica
(Elsevier, 2024)[Abstract] Megasphaera hexanoica is a bacterial strain following the reverse β-oxidation pathway to synthesize caproate (CA) using lactate (LA) as an electron donor (ED) and acetate (AA) or butyrate (BA) as electron acceptors ... -
Effect of Endogenous and Exogenous Butyric Acid on Butanol Production From CO by Enriched Clostridia
(Frontiers, 2022-02-16)[Abstract] Butanol is a potential renewable fuel. To increase the selectivity for butanol during CO fermentation, exogenous acetic acid and ethanol, exogenous butyric acid or endogenous butyric acid from glucose fermentation ... -
Effect of key parameters on the removal of formaldehyde and methanol in gas-phase biotrickling filters
(Elsevier, 2006-12)The effect of some important operation parameters, as pH, pollutant load and composition of the nutrient media, on the biodegradation of a mixture of formaldehyde and methanol in a gas-phase biotrickling filter was studied. ... -
Effect of oil concentration and residence time on the biodegradation of α-pinene vapours in two-liquid phase suspended-growth bioreactors
(Elsevier, 2012-02-20)Recently, research on the use of binary aqueous–organic liquid phase systems for the treatment of polluted air has significantly increased. This paper reports the removal of α-pinene from a waste air stream in a continuous ... -
Effect of pH and medium composition on chain elongation with Megasphaera hexanoica producing C4-C8 fatty acids
(Frontiers Media, 2023)[Abstract] ntroduction: Chain elongation technology, which involves fermentation with anaerobic bacteria, has gained attention for converting short and medium chain substrates into valuable and longer-chain products like ... -
Effect of pH, Yeast Extract and Inorganic Carbon on Chain Elongation for Hexanoic Acid Production
(Elsevier, 2019-12-29)[Abstract] Several anaerobic bioconversion technologies produce short chain volatile fatty acids and sometimes ethanol, which can together be elongated to hexanoic acid (C6 acid) by Clostridium kluyveri in a secondary ... -
Effect of phenol on the biological treatment of wastewaters from a resin producing industry
(Elsevier, 2008-06)The effect of phenol on the biological treatment of wastewaters from a resin producing industry was analyzed in a pre-denitrification system. First, the effect of phenol overloads on the removal of organic matter and ... -
Effect of salinity on C1-gas fermentation by "Clostridium carboxidivorans" producing acids and alcohols
(Springer Nature, 2019-07-17)[Abstract] Clostridium carboxidivorans can produce acids and/or alcohols through syngas fermentation. In that C1-gas fermentation process, the production of acids takes place at higher pH (acetogenesis) (e.g., around 6.00), ... -
Effects of pH, CO2, and flow pattern on the autotrophic degradation of hydrogen sulfide in a biotrickling filter
(Wiley-Blackwell, 2005-11)In this study, the effects of pH, CO2, and flow pattern on the performance of a biotrickling filter (BTF) packed with plastic Pall rings and treating a H2S-polluted waste gas were investigated to establish the optimum ... -
Efficient Production of 𝑛-Caproate From Syngas by a Co-culture of Clostridium Aceticum and Clostridium Kluyveri
