Microbial processes and bacterial populations associated to anaerobic treatment of sulfate-rich wastewater [PDF]

, 2010
A pilot-scale (1.2 m3) anaerobic sequencing batch biofilm reactor (ASBBR) containing mineral coal for biomass attachment was fed with sulfate-rich wastewater at increasing sulfate concentrations. Ethanol was used as the main organic source.

Perception‐transduction‐transmission separation bionic H2S sensor

InfoScience, EarlyView.
The modular separation of biological olfactory systems boasts unparalleled efficiency in olfactory recognition. Introducing this perception‐transduction‐transmission separation design into chemiresistive gas sensors (bionic olfactory sensing) based on the heterojunction rectification effect overcomes the inherent limitations of traditional sensor ...

Redox-dependent rearrangements of the NiFeS cluster of carbon monoxide dehydrogenase

eLife, 2018
The C-cluster of the enzyme carbon monoxide dehydrogenase (CODH) is a structurally distinctive Ni-Fe-S cluster employed to catalyze the reduction of CO2 to CO as part of the Wood-Ljungdahl carbon fixation pathway.

Microbially Influenced Corrosion in Epoxy‐Ceramic Coated Carbon‐Steel Cooler

Materials and Corrosion, EarlyView.
A significant localization of corrosion attacks up to 1 mm deep were found in coated carbon‐steel cooler. Corrosion products and biofilm were enriched in mixed bacterial community including the genera Sulfuritalea and Methylotenera. Analysis of metabolic markers confirmed their coexistence with sulfate‐reducing bacteria.

Anode potential influences the structure and function of anodic electrode and electrolyte-associated microbiomes [PDF]

, 2016
Three bioelectrochemical systems were operated with set anode potentials of +300 mV, +550 mV and +800 mV vs. Standard Hydrogen Electrode (SHE) to test the hypothesis that anode potential influences microbial diversity and is positively associated with ...

Grape Seed Proanthocyanidins: A Potential Microbiome‐Targeted Intervention for Healthy Aging in Rats

Molecular Nutrition &Food Research, EarlyView.
Grape seed proanthocyanidin extract (GSPE) promotes a healthier gut phenotype in aged rats. Aging alters gut microbiota composition, increases inflammation, and compromises intestinal barrier function. This study shows that short‐term GSPE treatment in aged rats partially restores microbial diversity toward a youthful profile, modulates mucus‐related ...

Restricted intake of sulfur-containing amino acids reversed the hepatic injury induced by excess Desulfovibrio through gut–liver axis

Gut Microbes
Diet is a key player in gut–liver axis. However, the effect of different dietary patterns on gut microbiota and liver functions remains unclear. Here, we used rodent standard chow and purified diet to mimic two common human dietary patterns: grain and ...

Anaerobic 4-hydroxyproline utilization: Discovery of a new glycyl radical enzyme in the human gut microbiome uncovers a widespread microbial metabolic activity. [PDF]

, 2018
The discovery of enzymes responsible for previously unappreciated microbial metabolic pathways furthers our understanding of host-microbe and microbe-microbe interactions. We recently identified and characterized a new gut microbial glycyl radical enzyme

Multi‐omics reveal the gut microbiota‐mediated severe foraging environment adaption of small wild ruminants in the Three‐River‐Source National Park, China

Integrative Zoology, EarlyView.
This research reveals the gut microbiota‐mediated severe foraging environment adaptation of wild small ruminants in the Three‐River‐Source National Park. Unlike Tibetan sheep (TS), blue sheep (PN and Tibetan antelope (TA) often grazed low‐quality herbage in a wildness environment, and the higher microbial diversity and resilient network characteristics
