Benthic microbiology is the study of microorganisms that inhabit the benthos, the ecological region at the lowest level of a body of water, including the sediment surface and sub-surface layers. These microorganisms, primarily bacteria, archaea, and fungi, play crucial roles in benthic ecosystems. They are involved in nutrient cycling, decomposition of organic matter, and the transformation of various chemical compounds.

These microscopic life forms are highly adapted to the often challenging conditions of their environment, which can include low oxygen levels, high pressure, and limited nutrient availability. They can be found in diverse benthic habitats ranging from shallow coastal waters to the deep sea, and from freshwater lakes to polar ice-covered regions.

Benthic microbes are essential for the overall health and functioning of aquatic environments. For instance, they are key players in the degradation of pollutants and the recycling of essential elements like nitrogen, phosphorus, and sulfur. Their activity influences the biogeochemical cycles that support all life in the water column and surrounding ecosystems. Research in benthic microbiology uses various techniques, including direct sampling of sediments and water, molecular biology methods to identify microbial communities, and incubation experiments to study their metabolic activities. Understanding these microbial communities is vital for assessing the impact of human activities, such as pollution and climate change, on aquatic ecosystems.
