The potential of caproate (hexanoate) production using Clostridium kluyveri syntrophic cocultures with Clostridium acetobutylicum or Clostridium saccharolyticum

Frontiers in Bioengineering and Biotechnology, 2022
Caproate (hexanoate) and other medium-chain fatty acids are valuable platform chemicals produced by processes utilizing petroleum or plant oil. Clostridium kluyveri, growing on short chain alcohols (notably ethanol) and carboxylic acids (such as acetate)

Species‐Specific Optimisation and Environmental Regulation of Biofilm Formation in Enterobacter cloacae: Inhibitory Role of Glucose in Biofilm Development

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
This study demonstrates that mild salinity stress (1%–2% NaCl) significantly enhances biofilm formation in Enterobacter cloacae. Using a standardised 96‐well microtiter plate assay, we optimised in vitro biofilm quantification and classification, providing a reproducible framework for studying environmental and clinical biofilm development mechanisms ...

Evaluation of Media Components and Process Parameters in a Sensitive and Robust Fed-Batch Syngas Fermentation System with Clostridium ljungdahlii

Fermentation, 2020
The fermentation of synthesis gas, or syngas, by acetogenic bacteria can help in transitioning from a fossil-fuel-based to a renewable bioeconomy. The main fermentation products of Clostridium ljungdahlii, one of such microorganisms, are acetate and ...

Multi‐Targeting Non‐Specific Genome Engineering in Bacteria

Advanced Science, Volume 13, Issue 25, 4 May 2026.
In this study, we provide the first case to use the multi‐targeting integrase (MTI) systems in bacteria and develop a host‐independent generalizable approach, MNGE (Multi‐targeting Non‐specific Genome Engineering), for multi‐copy and random integration of metabolic genes or pathways in both Gram‐positive and Gram‐negative bacteria, which will ...

Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 3, May/June 2026.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Emerging Technologies for Biobutanol Production via Syngas Fermentation

GCB Bioenergy, Volume 18, Issue 5, May 2026.
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...

Careful CO Addition Enhances Autotrophic d‐Lactate Formation With Engineered Acetobacterium woodii

Engineering in Life Sciences, Volume 26, Issue 2, February 2026.
ABSTRACT The acetogen A. woodii efficiently converts CO2 and H2 to acetate. Metabolic engineering enabled the autotrophic production of non‐native products, for example, d‐lactate from CO2 by overexpression of d‐lactate dehydrogenase from Leuconostoc mesenteroides and knockout of the native lactate dehydrogenase. During gas fermentation with acetogens,

Carboxydotrophic Acetogenesis in Alkaline Conditions Results in Transient Formate Production by the Halo‐Alkaliphilic Acetogen Haloacetibacter carboxydivorans Gen. Nov. sp. Nov

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This work presents the physiological exploration of the halo‐alkaliphilic, carboxydotrophic acetogen bacterium MD4. In contrast to well‐characterised neutrophilic and slightly acidophilic acetogenic carboxydotrophs, this work shows an important role for formate production, instead of ethanol, as a redox exhaust mechanism in alkaline conditions ...
