Identification and characterization of two functionally unknown genes involved in butanol tolerance of Clostridium acetobutylicum. [PDF]
PLoS ONE, 2012 Solvents toxicity is a major limiting factor hampering the cost-effective biotechnological production of chemicals. In Clostridium acetobutylicum, a functionally unknown protein (encoded by SMB_G1518) with a hypothetical alcohol interacting domain was ...

Pentose Metabolism in Clostridium acetobutylicum [PDF]
Agricultural and Biological Chemistry, 1969 L-Arabinose ketol-isomerase (EC 5. 3. 1. 4) was extracted from the L-arabinose-grown cells of Clostridium acetobutylicum and partially purified by ammonium sulfate fractionation, DEAE-cellulose column chromatography and the gel filtration on Sephadex G-200. Optimum pH and temperature for the activity of the enzyme were 7.5 and 37°C, respectively.

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 ...

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 ...

Biotechnology and Bioengineering, Volume 123, Issue 4, Page 1036-1049, April 2026.ABSTRACT Isobutanol is a fusel alcohol that can be produced microbially for use as a biofuel or upgraded into sustainable aviation fuel (SAF). A key enzyme in the isobutanol biosynthetic pathway is 2‐ketoacid decarboxylase (KDC), which irreversibly decarboxylates 2‐ketoisovalerate (KIV) to yield isobutyraldehyde.
