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.

Electrobiocorrosion by Microbes without Outer-Surface Cytochromes

This study identifies which methanogens and acetogens can perform electrobiocorrosion without outer-surface cytochromes, showing multiple strategies for electron transfer to Fe0.

Detrimental Impact of a Type VI Secretion System on Direct Interspecies Electron Transfer

This study shows that the type VI secretion system in Geobacter metallireducens affects DIET by altering gene expression and electron transfer efficiency.

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.

Direct Observation of Electrically Conductive Pili Emanating from Geobacter sulfurreducens

This paper directly observes electrically conductive pili (e-pili) in Geobacter sulfurreducens using atomic force microscopy, confirming their role in long-range extracellular electron transport.

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.

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.

Structure of a cytochrome-based bacterial nanowire

Cryo-electron microscopy reveals the structure of a c-type cytochrome filament forming a bacterial nanowire in Geobacter sulfurreducens.

The Archaellum of Methanospirillum hungatei is Electrically Conductive

The paper demonstrates that the archaellum of Methanospirillum hungatei is electrically conductive, identifying a core of phenylalanines as a potential electron-conducting pathway.

Potential for Methanosarcina to contribute to uranium reduction during acetate-promoted groundwater bioremediation

This study shows Methanosarcina can reduce uranium in groundwater after Fe(III) oxides are depleted, suggesting a new role in bioremediation.

Electrically Conductive Pili from Pilin Genes of Phylogenetically Diverse Microorganisms

This study expresses pilin genes from diverse microorganisms in Geobacter sulfurreducens to identify new sources of electrically conductive pili, finding that some produce e-pili with properties similar to native ones.
