Volcanic microbe eats CO2 ‘astonishingly quickly’, say scientists

Discovery of carbon-capturing organism in hot springs could lead to efficient way of absorbing climate-heating gas

A microbe discovered in a volcanic hot spring gobbles up carbon dioxide “astonishingly quickly”, according to the scientists who found it.

The researchers hope to utilise microbes that have naturally evolved to absorb CO2 as an efficient way of removing the greenhouse gas from the atmosphere. Ending the burning of fossil fuels is critical in ending the climate crisis, but most scientists agree CO2 will also need to be sucked from the air to limit future damage.

The new microbe, a cyanobacteria, was discovered in September in volcanic seeps near the Italian island of Vulcano, where the water contains high levels of CO2. The researchers said the bug turned CO2 into biomass faster than any other known cyanobacteria.

In February the team also explored hot springs in the Rocky Mountains in Colorado, US, where levels of CO2 are even higher. Those results are now being analysed. The researchers said all their data on microbes would be published and made available to other scientists as a database that pairs DNA sequences with banked samples of the bacteria.

Dr Braden Tierney, at Weill Cornell Medical College and Harvard Medical School, said: “Our lead collaborator at Harvard isolated this organism that grew astonishingly quickly, compared to other cyanobacteria.”

“The project takes advantage of 3.6bn years of microbial evolution,” he said. “The nice thing about microbes is that they are self-assembling machines. You don’t have that with a lot of the chemical approaches [to CO2 capture].”

The new microbe had another unusual property, Tierney said: it sinks in water, which could help collect the CO2 it absorbs.

But the microbe was not a silver bullet, Tierney said. “There really isn’t a one-size-fits-all solution to climate change and carbon capture. There will be circumstances where the tree is going to outperform microbes or fungi. But there will also be circumstances where you really want a fast-growing aquatic microbe that sinks,” he said. That might include large, carbon-capturing ponds, he said. The microbe might also be able to produce a useful bioplastic.

Recent Research Unveils New Genomic Landscape of the Human Gut Microbiome

BGI-Research introduced CGR2, the expanded cultivated genome reference landscape for the human gut microbiome.

Scientists from BGI-Research developed a new version of the Cultivated Genome Reference (CGR), a repository of high-quality draft genomes of the human gut microbiome. The current version of CGR, which is CGR2, has been further expanded to incorporate numerous high-quality draft genomes generated from cultivated bacteria. CGR2 classifies previously unidentified species and uncovers the functional and genomic diversity of bacterial strains. An in-depth analysis of carbohydrate-active enzymes (CAzymes) reveals the phyla with the largest and most diverse repertoires of these enzymes. CGR2 also enabled the identification of genes involved in the synthesis of secondary metabolites in the gut microbiome. The unraveling of the gut microbiome genomic landscape will enable the development of therapeutics and provide a deep insight into the evolution of the human gut microbiome.

hi- quick question since I know you're someone who's written several papers- Do you know if you/other people who have written scientific papers are okay with emails about questions about those papers?

I'm someone who studies hyenas- amateurishly -and papers about extinct species of hyenas are really interesting to me but I can't exactly digest them very well because I don't understand the words being used. Like, what in heavens names is a 'metaconid' what does this mean!!!!!

In general authors are happy to receive such questions, but might not have enough time to give you the answer you are looking for. Still, always worth reaching out.

A metaconid is a part of a molar. But I understand this is just an example among of the general issue you are trying to illustrate. What I have learned from years of reading unfamiliar jargon, and listening to podcasts like The Tetrapod Zoology Podcast that use jargon with reckless abandon, is that in general either (a) the words that are encoded in jargon aren't *that* important to understand the grand themes of what is being discussed, or (b) their meaning can be deduced based on context cues. When I come across one that is key but really cannot be deduced, I will google it, and often Wiktionary or similar will have an answer.

The more you read, the more familiar you will get with the jargon, and the less you will need to google or ask. So, I encourage you to read broadly, and chase those interests!
