Sediment microbiome
Oceans cover 70% of the Earth while sedimentary habitats cover most of the ocean bottom (ranging from gravel to fine muds), making this the largest ecosystem on our planet in areal coverage. Surface sediment bacteria play a significant ecological and biogeochemical role in marine ecosystems due to their high abundance relative to the overlying water column, and they play a key role in the decomposition of the organic matter, nutrient…
