Metabolism of adenylylated nucleotides in Clostridium acetobutylicum [PDF]

Journal of Bacteriology, 1988
In response to the stresses imposed by temperature upshift or addition of butanol, Clostridium acetobutylicum cultures accumulated diadenosine-5',5'''-P1,P4-tetraphosphate (Ap4A) and adenosine 5'-P1,P4-tetraphospho-5'-guanosine (Ap4G) to high levels.

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 ...

Cellulolytic Activity of Clostridium acetobutylicum [PDF]

Applied and Environmental Microbiology, 1985
Clostridium acetobutylicum NRRL B527 and ATCC 824 exhibited extracellular and cell-bound endoglucanase and cellobiase activities during growth in a chemically defined medium with cellobiose as the sole source of carbohydrate. For both strains, the endoglucanase was found to be mainly extracellular (70 to 90%) during growth in ...

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.

DNA transfer between two different species mediated by heterologous cell fusion in Clostridium coculture

mBio
Prokaryotic evolution is driven by random mutations and horizontal gene transfer (HGT). HGT occurs via transformation, transduction, or conjugation. We have previously shown that in syntrophic cocultures of Clostridium acetobutylicum and Clostridium ...

Iterative Genome Engineering Platform Enables Efficient Sucrose Biosynthesis From CO2 in Photosynthetic Synechococcus elongatus UTEX 2973

Plant Biotechnology Journal, EarlyView.
ABSTRACT The single crossover occurring via homologous recombination is a common phenomenon existing among microbes like Escherichia coli, Bacillus subtilis, Vibrio natriegens, Gluconobacter oxydans and most cyanobacteria species, threatening the stability of engineered strains and challenging iterative genetic engineering. Among them, we take the fast‐

Intervention With Lacticaseibacillus paracasei PC‐01 Fermented Milk Beverage Ameliorates Functional Dyspepsia and Modulates Gut Microbiome: A Pilot Study

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
This study confirmed that intake of the Lacticaseibacillus paracasei PC‐01 fermented milk beverage can significantly alleviate symptoms in patients with functional dyspepsia. It markedly increases the abundances of Lacticaseibacillus paracasei and Blautia, while reducing the abundance of Enterobacter roggenkampi.

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 ...
