Efficient production of n-caproate from syngas by a co-culture of Clostridium aceticum and Clostridium kluyveri

Journal of Environmental Management, 2022
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) and bioalcohols, in an attempt to integrate the concept of circular economy in the industry.

Small RNAs in the Genus Clostridium

mBio, 2011
The genus Clostridium includes major human pathogens and species important to cellulose degradation, the carbon cycle, and biotechnology. Small RNAs (sRNAs) are emerging as crucial regulatory molecules in all organisms, but they have not been ...

Biological Routes for Biohydrogen Production: A Clean and Carbon‐Free Fuel

Biotechnology Journal, Volume 20, Issue 7, July 2025.
Graphical Abstract and Lay Summary Biological routes for hydrogen (H2) production are mainly classified into four pathways: 1) direct bio‐photolysis, 2) indirect bio‐photolysis, 3) photo‐fermentation, and 4) dark fermentation. Of these pathways, dark fermentation produces the highest levels of H2 production.

Microbial Communities in Agave Fermentations Vary by Local Biogeographic Regions

Environmental Microbiology Reports, Volume 17, Issue 1, February 2025.
We performed a country‐wide metabarcoding analysis of the microbial communities associated with the fermentations used for the production of artisanal agave spirits in Mexico. Despite the biogeographic and cultural differences of the producing sites, we identified a core of bacteria and fungi that are common in most fermentations.

Evaluation of Yeast Alcohol Acetyltransferases for Ethyl Acetate Production in Clostridium ljungdahlii

Engineering in Life Sciences, Volume 25, Issue 1, January 2025.
ABSTRACT Sustainable chemical production from C1 gaseous substrates, such as syngas or CO2/H2, can be achieved through gas fermentation. In gas fermentation, acetogenic bacteria are able to utilize oxidized inorganic carbon sources as the sole carbon source and electron acceptor, while reduced inorganic species are used as the electron donor ...

Flavin-Based Electron Bifurcation, Ferredoxin, Flavodoxin, and Anaerobic Respiration With Protons (Ech) or NAD+ (Rnf) as Electron Acceptors: A Historical Review

Frontiers in Microbiology, 2018
Flavin-based electron bifurcation is a newly discovered mechanism, by which a hydride electron pair from NAD(P)H, coenzyme F420H2, H2, or formate is split by flavoproteins into one-electron with a more negative reduction potential and one with a more ...

Use of Deep Sequencing to Evaluate Transitions in Microbial Communities in Stranded Sargassum

International Journal of Microbiology, Volume 2025, Issue 1, 2025.
Deep sequencing technologies can be used to evaluate pathogens in environmental samples. The objective of this study was to use this technology to evaluate Sargassum samples that were characterized by different stranding times, one classified as short‐term stranded (STS) and another classified as long‐term stranded (LTS) Sargassum.

Reproducible, high-yielding, biological caproate production from food waste using a single-phase anaerobic reactor system

Biotechnology for Biofuels, 2018
Background Nowadays, the vast majority of chemicals are either synthesised from fossil fuels or are extracted from agricultural commodities. However, these production approaches are not environmentally and economically sustainable, as they result in the ...
