Subseafloor Microbial Communities Survive on Products of Radioactive Process, Study Suggests | Biology – Sci-News.com
Radiolytic products provide the dominant fuel for microbial activity in marine sediment older than a few million years, according to a new study.
Radionuclides are ubiquitous in sediment and rock, where their decay leads to the production of hydrogen and oxidized chemicals via radiolysis of water; these radiolytic products provide the dominant fuel for microbial activity in marine sediment older than a few million years; they may also be significant for sustaining life in subseafloor sediment and subsurface environments of other planets, according to a new study.
Global distribution of production rates of radiolytic hydrogen and radiolytic…
