Such a dramatic decline could turn the land from taking up carbon overall to pumping it out by 2100, as the rate of respiration by soil microbes, which exhale carbon dioxide, is predicted to increase in a warmer world.

But researchers report today that they've figured out how to predict the structures of hundreds of unmapped proteins by gleaning insights from one of the strangest of places: «metagenomics» projects that sequence DNA from broad swaths of microbes in the soils and seas.

Over the past several years, Metcalf and colleagues have developed a «microbial clock» to measure postmortem passage of time by genetically sequencing the population of microbes on the skin and in the surrounding soil.

That finding suggests that spore - forming microbes — including ones that humans carry with them — could survive in soils moistened by briny waters.

In collaboration with researchers in the US and Germany, Otago microbiologists have teased out the mechanisms by which the aerobic soil microbe Mycobacterium smegmatis is able to persist for extreme lengths of time in the absence, or near - absence, of oxygeIn collaboration with researchers in the US and Germany, Otago microbiologists have teased out the mechanisms by which the aerobic soil microbe Mycobacterium smegmatis is able to persist for extreme lengths of time in the absence, or near - absence, of oxygein the US and Germany, Otago microbiologists have teased out the mechanisms by which the aerobic soil microbe Mycobacterium smegmatis is able to persist for extreme lengths of time in the absence, or near - absence, of oxygein the absence, or near - absence, of oxygen.

By hosting fewer methane - producing microbes, the GM rice might alter the soil ecosystem in unknown ways, notes microbial ecologist Paul Bodelier of the Netherlands Institute of Ecology at Wageningen University in a commentary.

Researchers created SUSIBA2 rice by introducing a single gene from barley into common rice, resulting in a plant that can better feed its grains, stems and leaves while starving off methane - producing microbes in the soil.

Most of the antibiotics used to fight illness today were devised by soil microbes, which employ them as weapons in the competition for resources and survival.

This redistribution of soil carbon storage raises questions of whether the balance provided by larger plants will stand in the long term or whether the more active microbes detected in the deeper soils will eventually offset the increased carbon in those deeper soils.

A research team led by graduate student researcher Shannon Hagerty and Paul Dijkstra, biological sciences associate research professor, measured two key characteristics of soil microbes that determine their role in the soil carbon cycle: how efficiently they use carbon to grow and how long they live.

Pootakham on dynamics of coral ‐ associated microbiomes during a thermal bleaching event and a paper by X. Jiang on a novel auxotrophic interaction among soil microbes.

It is a microbe (bacteria) that is produced by microorganisms internally (synthesised in the gut) and elsewhere (e.g. in soil by microbes that live in a symbiotic relationship with plant roots).

Among an ever expanding (and as Karen Barad might say, «entangled») list, I am inspired by the complex and contradictory city I live in (the city of Chicago) and the incredible community of hard working, sincere, talented artists who I am surround by and have the privilege of working alongside and in collaboration with every day (too many and to diverse to name individually here) / / by mentors A.

The scientists found that almost 70 % of the organic carbon initially present in the weathered bedrock had been oxidised by soil microbes, to put, for every square kilometre they measured, somewhere between six and 18 tonnes of carbon back into the atmosphere.

Just the reduction in soil microbes would increase carbon sequestration by a few orders of magnitude.

It will be broken down by microbes and turned into methane in wet soil.

«In most climate models there is little or no accounting for the carbon fixed by soil microbes,» she says.

As inorganic mercury in our air, soil and water enters the oceans, aquatic microbes convert it to methylmercury — a form readily absorbed by sea life.

Given enough oxygen, decomposition of organic matter in soil is accompanied by the release of heat by microbes (similar to compost), which, during summer, might stimulate further permafrost thaw.

There's been a lot of hype on this topic, suggesting that it can massively increase soil carbon sequestration, boost food production by promoting soil microbes, and help us slow global climate change in the process.

If this site is really focusing on climate science, then we could perhaps discuss the recent article by S. Allison et al. in Nature Geoscience, which concludes that in response to increasing temperature there is a decrease of CO2 released from soil microbes.
