Discovery and Biosynthesis of Celluxanthenes, Antibacterial Arylpolyene Alkaloids From Diverse Cellulose-Degrading Anaerobic Bacteria. [PDF]

Angew Chem Int Ed Engl
The structure and biosynthetic origin of the enigmatic “yellow affinity substance” (YAS) from the anaerobe thermophile Clostridium thermocellum (now: Acetivibrio thermocellus) were elucidated. YAS is a complex of unusual antibacterial arylpolyene alkaloids (celluxanthenes) that are produced by various cellulolytic anaerobes.

Extracytoplasmic polysaccharides control cellulosomal and non-cellulosomal systems in Herbivorax saccincola A7. [PDF]

Appl Microbiol Biotechnol
Herbivorax saccincola A7 is an anaerobic alkali-thermophilic lignocellulolytic bacterium that possesses a cellulosome and high xylan degradation ability. To understand the expression profile of extracellular enzymes by carbon sources, quantitative real-time PCR was performed on all cellulosomal and non-cellulosomal enzyme genes of H.

Cellulosomes from Mesophilic Bacteria [PDF]

Journal of Bacteriology, 2003
Plant cell wall-degrading enzymes have become increasingly important, since the development of efficient biomass degradation methods and the conversion of sugars to valuable products such as butanol and amino acids and utilizable forms of energy such as ethanol and methane could lead to less dependence on imported petroleum as a fuel and chemical ...

How does cellulosome composition influence deconstruction of lignocellulosic substrates in Clostridium (Ruminiclostridium) thermocellum DSM 1313?

Biotechnology for Biofuels, 2017
Background Bioethanol production processes involve enzymatic hydrolysis of pretreated lignocellulosic biomass into fermentable sugars. Due to the relatively high cost of enzyme production, the development of potent and cost-effective cellulolytic ...

Study on the construction technology of β-alanine synthesizing Escherichia coli based on cellulosome assembly

Frontiers in Bioengineering and Biotechnology, 2023
Introduction: β-Alanine is the only β-amino acid in nature; it is widely used in food additives, medicines, health products, and surfactants. To avoid pollution caused by traditional production methods, the synthesis of β-alanine has been gradually ...
