The microbial loop describes a trophic pathway in the marine microbial food web where dissolved organic carbon (DOC) is returned to higher trophic levels via its incorporation into bacterial biomass, and then coupled with the classic food chain formed by phytoplankton-zooplankton-nekton.The term microbial loop was coined by Azam et al. (Fenchel 2008) to include the role played by bacteria in

'microbial loop' is primarily based on work with batch cultures (Andersen & Fenchel 1985) or on studies of estuarine environments (Andersen & Sorensen 1986, Bj0rnsen et al.

The microbial loop comprises bacteria, flagellates, ciliates, and other micro-zooplankton (less than 200 µm in diameter) in the water column. Its significance has only recently been appreciated, and it has been investigated in a sandy-beach/surf-zone context solely in the Eastern Cape ( McLachlan and Romer 1990 , McGwynne 1991 ).

In soil systems, the microbial loop refers to soil carbon. By consuming the molecules, bacteria are reintroducing critical energy back into the food web when slightly larger creatures, like krill, eat the bacteria. This process is known as the microbial loop.

the microbial loop. About one-half of the oxygen in every breath we take derives from photosyn-thetic bacteria within the marine micro-bial loop. Bacteria manage to populate all parts of the ocean by capturing nutri-ents and energy from diverse sources. Photosynthetic bacteria carry out much of the primary production of organic

Rhizobacteria are strongly top‐down regulated by microfaunal grazers, particularly protozoa. Consequently, beneficial effects of protozoa on plant growth have been assigned to nutrients released from consumed bacterial biomass, that is, the ‘microbial loop’.

Conclutions (microbial loop) • The microbial loop is a model of pathways of carbon and nutrient cycling through microbial components of pelagic aquatic communities. • Protistan zooplankton are the most important microbial consumers and have major functions … 2019-07-08 2008-11-15 Figure 5.2 A simplified schematic illustration of the microbial loop (bacteria and protozoans) and how it fits in with the basic pelagic grazing food chain (phytoplankton to piscivorous fish).
