Carbon Monoxide as an Electron Donor for the Biological Reduction of Sulphate [PDF]
, 2010 Several strains of Gram-negative and Gram-positive sulphate-reducing bacteria (SRB) are able to use carbon monoxide (CO) as a carbon source and electron donor for biological sulphate reduction.

Latent infection of low-virulence anaerobic bacteria in degenerated lumbar intervertebral discs
BMC Musculoskeletal Disorders, 2018 Background The existence of latent low-virulence anaerobic bacteria in degenerated intervertebral discs (IVDs) remains controversial. In this study, the prevalence of low-virulence anaerobic bacteria in degenerated IVDs was examined, and the correlation ...

Trophic Diversity in Duckweed: Mixotrophy, More Than the Sum of its Extremes
Advanced Science, EarlyView.In the context of rising DOC in aquatic environments, mixotrophic duckweed may impact carbon cycling by acting as either a carbon sink, as they absorb CO2 through photosynthesis, or a carbon source, as they release CO2 through respiration of absorbed DOC, which depends on DOC concentration, light availability, temperature, and other environmental ...

Enhancing anaerobic degradation of lipids in wastewater by addition of co-substrate
, 2002 Anaerobic treatment systems are becoming increasingly popular to treat complex organic wastes that contain carbohydrates, proteins and lipids. Lipids are widely found in sewage and industrial wastewaters.

Methane oxidation and emission in Lake Lugano (Southern Switzerland) : a lipid biomarker and isotopic approach [PDF]
, 2015 Methane is an important greenhouse gas in Earth's atmosphere. The sources of atmospheric methane are largely biogenic, being produced under anoxic conditions by methanogenic Archaea.

Advanced Science, EarlyView.A unique mechanism of catalytic bias regulated by diaphorase‐like subunit in formate dehydrogenase from Rhodobacter aestuarii is revealed. The diaphorase‐like subunit functions act as a biological “voltage rheostat” that controls the slow release of NADH to regulate redox balance, biasing the enzyme's catalytic preference toward CO2 reduction over ...

, 1991 Laboratory scale experiments and measurements on full scale, overloaded, anaerobic digesters showed that large levels of volatile fatty acids can accumulate leading to digester acidification, although the hydrogen partial pressure was relatively low 1 ...

Nature Communications, 2019 Anaerobic bacteria represent a rich source of biological and chemical diversity but are difficult to cultivate and there is a lack of heterologous expression systems. Here the authors develop an expression system based on S. mutans UA159 for biosynthetic

Advanced Science, EarlyView.An edible biohybrid platform triggers nanoplastics (NPs) aging and agglomeration by in situ generating hydroxyl radicals within the intestine. The enlarged NPs are unable to penetrate the intestine and are subsequently excreted. Simultaneously, probiotic biofilms reinforce the intestinal barrier.
