Re­search­ers cul­tiv­ate ar­chaea that break down crude oil in novel ways

How mi­croor­gan­isms deep in the seabed render crude oil harm­less

05-Jun-2023 - The sea­floor is home to around one-third of all the mi­croor­gan­isms on the Earth and is in­hab­ited even at a depth of sev­eral kilo­met­ers. Only when it be­comes too hot does the abund­ance of mi­croor­gan­isms ap­pear to de­cline. But how, and from what, do mi­croor­gan­isms in the deep ...

Ex­plan­a­tion for un­usual iso­tope pat­terns

In a labor­at­ory ex­per­i­ment, re­search­ers sim­u­late al­tern­at­ive hy­dro­car­bon form­a­tion through re­duc­tion of acetic acid

15-Nov-2021 - Hy­dro­car­bons, which are an es­sen­tial com­pon­ent of crude oil and nat­ural gas, form un­der pres­sure and high tem­per­at­ures in the deep ocean floor. In the Guay­mas Basin in the Gulf of Cali­for­nia, re­search­ers have de­tec­ted hy­dro­car­bon gas pat­terns that could not have been ...

Microorganisms produce elemental carbon

Researchers identify a new kind of pure carbon production by microorganisms

29-Oct-2021 - Life on the Earth is based on carbon. Through the course of evolution, living organisms have learned to form and process large numbers of different carbon compounds. Carbon is the cornerstone of most biologically produced organic compounds such as proteins, carbohydrates, fats and DNA. All of ...
