Microbial Community and Metabolic Pathways in Anaerobic Digestion of Organic Solid Wastes: Progress, Challenges and Prospects

Fermentation
Anaerobic digestion (AD) is a sustainable and widely adopted technology for the treatment of organic solid wastes (OSWs). However, AD efficiency varies significantly across different substrates, primarily due to differences in the microbial community and

Native iron reduces CO2 to intermediates and end-products of the acetyl-CoA pathway

, 2018
Autotrophic theories for the origin of life propose that CO2 was the carbon source for primordial biosynthesis. Among the six known CO2 fixation pathways in nature, the acetyl-CoA (AcCoA; or Wood–Ljungdahl) pathway is the most ancient, and relies on ...

Mechanism of pyruvate ferredoxin oxidoreductase and role of the (4Fe-4S) cluster of the corrinoid iron sulfur protein in acetyl COA synthesis by the Wood Ljungdahl pathway

, 1997
Pyruvate ferredoxin oxidoreductase (PFOR) catalyzes the oxidative decarboxylation of pyruvate to acetyl CoA and CO$\sb2.$ By using rapid freeze quench EPR and stopped-flow spectroscopy the three elementary steps that constitute the first reductive half ...

Evolutionary Routes to Modern Metabolic Pathways

Macromol
Metabolism, the network of biochemical reactions that powers life, arose under conditions radically different from those on Earth today. Investigating its origins reveals how initially simple chemical processes gradually integrated nucleic acid and then ...

Engineered acetogenic bacteria as microbial cell factory for diversified biochemicals

Frontiers in Bioengineering and Biotechnology
Acetogenic bacteria (acetogens) are a class of microorganisms with conserved Wood-Ljungdahl pathway that can utilize CO and CO2/H2 as carbon source for autotrophic growth and convert these substrates to acetate and ethanol. Acetogens have great potential

Supplementary Material for: Substrate-Dependent Regulation of Carbon Catabolism in Marine Sulfate-Reducing Desulfobacterium autotrophicum HRM2

, 2017
Desulfobacterium autotrophicum HRM2 is a metabolically versatile sulfate-reducing bacterium, capable of heterotrophic (e.g. with organic acids and alcohols) and chemolithoautotrophic growth (with H2/CO2).
