Electron transport phosphorylation in rumen butyrivibrios: unprecedented ATP yield for glucose fermentation to butyrate. [PDF]

, 2015
From a genomic analysis of rumen butyrivibrios (Butyrivibrio and Pseudobutyrivibrio sp.), we have re-evaluated the contribution of electron transport phosphorylation (ETP) to ATP formation in this group.

Evaluation of enzymatic pretreatment strategies to enhance anaerobic digestion of tomato waste

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 1677-1689, November/December 2025.
Abstract Tomato residues are a form of solid waste that can be converted into methane through anaerobic digestion (AD). However, methane production is often limited due to incomplete hydrolysis caused by the high lignocellulosic content of tomato waste.

Biophysical and biochemical studies support TP0094 as a phosphotransacetylase in an acetogenic energy-conservation pathway in Treponema pallidum.

PLoS ONE, 2023
The mechanisms of energy generation and carbon-source utilization in the syphilis spirochete Treponema pallidum have remained enigmatic despite complete genomic sequence information. Whereas the bacterium harbors enzymes for glycolysis, the apparatus for

Global trends and challenges in biogas purification and CO2 capture for renewable energy and climate mitigation

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 6, Page 2474-2494, November/December 2025.
Abstract Biogas purification technologies facilitate the production of value‐added products such as biomethane and industrial chemicals. This review was based on the assumption that biogas purification is underrepresented in the literature despite its significant potential for clean energy and greenhouse gas mitigation, warranting a comprehensive ...

Acetate Shock Loads Enhance CO Uptake Rates of Anaerobic Microbiomes

Microbial Biotechnology
Pyrolysis of lignocellulosic biomass commonly produces syngas, a mixture of gases such as CO, CO2 and H2, as well as an aqueous solution generally rich in organic acids such as acetate.

Limits to dihydrogen incorporation into electron sinks alternative to methanogenesis in ruminal fermentation

Frontiers in Microbiology, 2015
Research is being conducted with the objective of decreasing methane (CH4) production in the rumen, as methane emissions from ruminants are environmentally damaging and a loss of digestible energy to ruminants. Inhibiting ruminal methanogenesis generally
