Open AccessMetaproteomics-informed stoichiometric modeling reveals the responses of wetland microbial communities to oxygen and sulfate exposure
Climate changes significantly impact greenhouse gas emissions from wetland soil. Specifically, wetland soil may be exposed to oxygen (O2) during droughts, or to sulfate (SO42-) as a result of sea level rise. How ...

Open AccessCatabolism and interactions of uncultured organisms shaped by eco-thermodynamics in methanogenic bioprocesses
Current understanding of the carbon cycle in methanogenic environments involves trophic interactions such as interspecies H2 transfer between organotrophs and methanogens. However, many metabolic processes are th...

Introduction to Microbial Hydrocarbon Production: Bioenergetics
Microorganisms play an essential role in the global carbon budget with methanogenesis being a significant global source of methane. The ability to produce hydrocarbons other than methane is widespread among mi...

Methanogens: Syntrophic Metabolism
Syntrophy is a mutualistic interaction in which two metabolically different types of microorganisms are linked by the need to keep metabolites exchanged between the two partners at low concentrations to make t...

Use of Biosurfactants in Oil Recovery
Biosurfactant-mediated oil recovery has the potential to recover large amounts of crude oil that remain entrapped in oil reservoirs after current oil recovery technologies reach their economic limit. Lipopepti...

Open AccessComplete genome sequence of Syntrophobacter fumaroxidans strain (MPOBT)
Syntrophobacter fumaroxidans strain MPOBT is the best-studied species of the genus Syntrophobacter. The species is of interest because of its anaerobic syntrophic lifestyle, its involvement in the conversion of p...

Biosurfactant-producing Bacillus are present in produced brines from Oklahoma oil reservoirs with a wide range of salinities
Nine wells producing from six different reservoirs with salinities ranging from 2.1% to 15.9% were surveyed for presence of surface-active compounds and biosurfactant-producing microbes. Degenerate primers wer...

Basis for formulating biosurfactant mixtures to achieve ultra low interfacial tension values against hydrocarbons
Biosurfactants could potentially replace or be used in conjunction with synthetic surfactants to provide for more cost-effective subsurface remediation. The design of surfactant formulations that are effective...

Article
Anaerobic microbial metabolism can proceed close to thermodynamic limits
Many fermentative bacteria obtain energy for growth by reactions in which the change in free energy (ΔG′) is less than that needed to synthesize ATP1,2,3,4. These bacteria couple substrate metabolism directly to ...

Geovibrio ferrireducens, a phylogenetically distinct dissimilatory Fe(III)-reducing bacterium
A new, phylogenetically distinct, dissimilatory, Fe(III)-reducing bacterium was isolated from surface sediment of a hydrocarbon-contaminated ditch. The isolate, designated strain PAL-1, was an obligately anae...
