Electric syntrophy-driven modulation of Fe0-dependent microbial denitrification
Water ResearchIn natural or engineered anaerobic environments, iron oxidation-driven microbial denitrification plays a critical role in the water or wastewater treatment. Herein, we report a previously unidentified metallic iron (Fe0)-dependent denitrification mode driven by the electro-syntrophic interaction between electroactive microorganism and denitrifier. In a

Hydrogen-based syntrophy in an electrically conductive biofilm anode
Chemical Engineering Journal, 2019Abstract We experimentally and theoretically investigated implications of H2 and a rate-limiting step in a mixed-culture biofilm anode fed with n-butyrate, one of the poorest substrates to exoelectrogens. Acetate and i-butyrate were formed as intermediates during anaerobic degradation of n-butyrate, which suggested oxidative acetogenesis of n ...

Redox-active humics support interspecies syntrophy and shift microbial community
Science China Technological Sciences, 2019The network of microbial electron transfer can establish a syntrophic association of microbes by connecting interspecies metabolisms, and a variety of redox-active shuttles in environment have been proved to accelerate the electron flow in a microbial community.

Thermodynamic Ecology of Hydrogen-Based Syntrophy
2006The energy available for metabolism in many anoxic ecosystems is so minimal that organisms are forced to live at the fundamental energetic threshold for life. Because organisms in these environments are energy limited, and because the amount of energy generated during catabolism hardly exceeds the biological energy quantum, competition for reducing ...

Methanol transfer supports metabolic syntrophy between bacteria and archaea
NatureIn subsurface methanogenic ecosystems, the ubiquity of methylated-compound-using archaea-methylotrophic methanogens1-4-implies that methylated compounds have an important role in the ecology and carbon cycling of such habitats. However, the origin of these chemicals remains unclear5,6 as there are no known energy metabolisms that generate methylated ...

Metagenomics of petroleum muck: revealing microbial diversity and depicting microbial syntrophy
Archives of Microbiology, 2014Present study attempts in revealing taxonomic and functional diversity of microorganism from petroleum muck using metagenomics approach. Using Ion Torrent Personal Genome Machine, total of 249 Mb raw data were obtained which was analysed using MG-RAST platform.

HYDROGEN STRESS AND SYNTROPHY OF HYPERTHERMOPHILIC HETEROTROPHS AND METHANOGENS
2018Polyethylene glycol (PEG) hydrogels are tunable cell culture platforms that recapitulate tissue geometry, water content, and bulk modulus. Despite these benefits, PEG hydrogels elicit an acute immune response, limiting their use in regenerative medicine, and they critically underrepresent the cell-instructive proteins found in the extracellular matrix (
