  Methane-munching microbes

  Nardy Kip, Julia F. van Winden, Huub J. M. Op den Camp and an array of colleagues braved hostile acidic peat bogs around the world in a feat of truly collaborative research.

  Global prevalence of methane oxidation by symbiotic bacteria in peat-moss ecosystems

  The degradation of submerged Sphagnum mosses generates significant quantities of methane in peat bogs. A global survey of these mosses reveals the presence of an active population of methane-oxidizing bacteria.

  Phosphorus burial

  The formation and burial of calcium phosphate minerals removes large quantities of phosphorus from the ocean. Radiotracer experiments reveal that bacteria in marine sediments mediate the production of these mineral phases at remarkably fast rates.

  Microbial sequestration of phosphorus in anoxic upwelling sediments

  Organic phosphorus is removed from the ocean by its conversion to phosphorite. Laboratory incubations suggest that bacteria catalyse phosphorite formation, and that the rate of conversion is greatest under anoxic conditions.

  Extracellular electron transfer through microbial reduction of solid-phase humic substances

  The decay of soil and sedimentary organic matter yields organic compounds with a high molecular weight, termed humic substances. Sediment-incubation experiments suggest that microbial reduction of solid-phase humics can accelerate iron(III) oxide reduction in wetland soils.
