Syntrophy Goes Electric: Direct Interspecies Electron Transfer

Direct interspecies electron transfer (DIET) has biogeochemical significance, and practical applications that rely on DIET or DIET-based aspects of microbial physiology are growing. Mechanisms for have primarily been studied in defined cocultures which Geobacter species one the partners. Electrically conductive pili (e-pili) can be an important electrical conduit DIET. However, there may instances contacts made between transport proteins associated with outer membranes Alternatively, partners plug into carbon materials, such as granular activated carbon, cloth, biochar, long-range exchange without need e-pili.

Methane Feedbacks to the Global Climate System in a Warmer World

Reviews of Geophysics, Journal Year: 2018, Volume and Issue: 56(1), P. 207 - 250

Published: Feb. 16, 2018

Abstract Methane (CH 4 ) is produced in many natural systems that are vulnerable to change under a warming climate, yet current CH budgets, as well future shifts emissions, have high uncertainties. Climate has the potential increase emissions from critical such wetlands, marine and freshwater systems, permafrost, methane hydrates, through temperature, hydrology, vegetation, landscape disturbance, sea level rise. Increased these would turn induce further climate change, resulting positive feedback. Here we synthesize biological, geochemical, physically focused feedback literature, bringing together key findings of disciplines. We discuss environment‐specific processes, including microbial, physical, geochemical interlinkages timescales on which they operate, present state knowledge feedbacks immediate distant future. The important linkages between microbial activity discussed with aim better constrain sensitivity cycle predictions. determine wetlands will form majority up 2100. Beyond this timescale, permafrost environments could become more important. Significant atmosphere dissociation hydrates not expected near Our highlight importance quantifying whether consumption can counterbalance production scenarios.

Reverse Methanogenesis and Respiration in Methanotrophic Archaea

Archaea, Journal Year: 2017, Volume and Issue: 2017, P. 1 - 22

Published: Jan. 1, 2017

Anaerobic oxidation of methane (AOM) is catalyzed by anaerobic methane-oxidizing archaea (ANME) via a reverse and modified methanogenesis pathway. Methanogens can also the pathway to oxidize methane, but only during net production (i.e., "trace oxidation"). In turn, ANME produce enzymatic back flux). Net AOM exergonic when coupled an external electron acceptor such as sulfate (ANME-1, ANME-2abc, ANME-3), nitrate (ANME-2d), or metal (oxides). this review, reversibility essential differences between methanogens are described combining published information with domain based (meta)genome comparison archaeal methanotrophs selected archaea. These include abundances special structure methyl coenzyme M reductase multiheme cytochromes presence menaquinones methanophenazines. ANME-2a ANME-2d use acceptors other than for AOM, respectively. Environmental studies suggest that involved in sulfate-dependent AOM. ANME-1 seem different mechanism disposal electrons possibly less versatile ANME-2. Future research will shed light on molecular basis reversal methanogenic transfer types.
