Medium Composition Affects Microbial Corrosion Rates

The paper shows that medium composition affects microbial corrosion rates, with D. vulgaris outperforming D. ferrophilus in marine conditions despite initial assumptions about their mechanisms.

Elucidating Microbial Iron Corrosion Mechanisms with a Hydrogenase-Deficient Strain of Desulfovibrio vulgaris

This study investigates Fe0 corrosion by a hydrogenase-deficient mutant of Desulfovibrio vulgaris, showing H2 oxidation indirectly promotes corrosion via sulfide generation, not direct electron transfer.

H2 is a Major Intermediate in Desulfovibrio vulgaris Corrosion of Iron

This study shows that Desulfovibrio vulgaris uses H2 as an intermediary to accept electrons from iron, clarifying mechanisms of microbial iron corrosion under sulfate-reducing conditions.

Microbial nanowires with genetically modified peptide ligands to sustainably fabricate electronic sensing devices

The paper demonstrates a genetic method to modify microbial nanowires with peptide ligands to enhance sensor response for specific analytes like ammonia and acetic acid.

Generating Electricity from Water Evaporation Through Microbial Biofilms

This paper demonstrates that engineered microbial biofilms can generate electricity from water evaporation, achieving power densities higher than non-biological materials.

Pili Expression in Geobacter sulfurreducens Lacking the Putative Gene for the PilB Pilus Assembly Motor

This paper shows that deleting the PilB gene in Geobacter sulfurreducens does not prevent e-pili expression, challenging previous assumptions about gene deletion strategies for studying e-pili function.

Mechanisms for Electron Uptake by Methanosarcina acetivorans During Direct Interspecies Electron Transfer

This study identifies MmcA as a key outer-surface c-type cytochrome for DIET in M. acetivorans and shows that archaella and other membrane complexes are involved in electron processing for methane production.

Syntrophus Conductive Pili Demonstrate that Common Hydrogen-Donating Syntrophs can have a Direct Electron Transfer Option

The paper shows that Syntrophus aciditrophicus can use direct interspecies electron transfer via conductive pili, challenging the belief that hydrogen/formate transfer is the primary mechanism in syntrophic communities.

A Membrane-Bound Cytochrome Enables Methanosarcina acetivorans to Conserve Energy to Support Growth from Extracellular Electron Transfer

This study shows Methanosarcina acetivorans conserves energy via extracellular electron transfer using a membrane-bound cytochrome, MmcA, and identifies its role in electron transport pathways.
