Characterization of Two α-l-Arabinofuranosidases from Acetivibrio mesophilus and Their Synergistic Effect in Degradation of Arabinose-Containing Substrates

open access: yes, 2021
Arabinofuranosidases are important accessory enzymes involved in the degradation of arabinose-containing poly- and oligosaccharides. Two arabinofuranosidases from the recently described novel anaerobic cellulolytic bacterium Acetivibrio mesophilus ...

Evolution of glucuronoxylan side chain variability in vascular plants and the compensatory adaptations of cell wall–degrading hydrolases

open access: yesNew Phytologist, Volume 244, Issue 3, Page 1024-1040, November 2024.
Summary Polysaccharide structural complexity not only influences cell wall strength and extensibility but also hinders pathogenic and biotechnological attempts to saccharify the wall. In certain species and tissues, glucuronic acid side groups on xylan exhibit arabinopyranose or galactose decorations whose genetic and evolutionary basis is completely ...

Altering the substitution and cross‐linking of glucuronoarabinoxylans affects cell wall architecture in Brachypodium distachyon

open access: yesNew Phytologist, Volume 242, Issue 2, Page 524-543, April 2024.
Summary The Poaceae family of plants provides cereal crops that are critical for human and animal nutrition, and also, they are an important source of biomass. Interacting plant cell wall components give rise to recalcitrance to digestion; thus, understanding the wall molecular architecture is important to improve biomass properties.

Sulphur requirements for growth of Acetivibrio cellulolyticus

open access: yes, 1982
The sulphur requirement for growth of Acetivibrio cellulolyticus was determined using a mineral salts basal medium reduced with titanium(III) citrate and supplemented with 1% (w/v) cellobiose and 0.05% (w/v) yeast extract. Inorganic sulphide (Na2S 199H2O)

Isolation and characterization of an anaerobic, cellulolytic microorganism, Acetivibrio cellulolyticus gen. nov., sp. nov

open access: yes, 1980
A new genus of cellulolytic, gram-negative, nonsporeforming, anaerobic bacteria is described. The colonies produced by these bacteria on cellulose agar were round, clear, translucent, and cream-colored and had an undulate margin.

Pyrophosphate-free glycolysis in Clostridium thermocellum increases both thermodynamic driving force and ethanol titers

open access: yesBiotechnology for Biofuels and Bioproducts
Background Clostridium thermocellum is a promising candidate for production of cellulosic biofuels, however, its final product titer is too low for commercial application, and this may be due to thermodynamic limitations in glycolysis.

Metabolism of Acetivibrio cellulolyticus during optimized growth on glucose, cellobiose and cellulose

open access: yes, 1982
The growth of Acetivibrio cellulolyticus in 2.5 l batch cultures was optimized by controlling the growth pH at 6.7, the dissolved inorganic sulphide concentration at 0.4\u20130.6 mM, and by constant removal of hydrogen from the cultures by sparging with ...

The ultrastructure of Acetivibrio cellulolyticus, a recently isolated cellulolytic anaerobe

open access: yes, 1982
The surface and internal structure of air-dried, freeze-dried, or critical-point-dried cells of Acetivibrio cellulolyticus were determined by negative staining, and by scanning and transmission electron microscopy.

Accumulation of an iodophilic polysaccharide during growth of Acetivibrio cellulolyticus on cellobiose

open access: yes, 1981
Maximum growth of Acetivibrio cellulolyticus in 1% cellobiose (w/v, added as filter sterilized solution) medium was observed after about 24h of incubation at 35\ub0C.
