The microbial loop refers to the small microscopic organisms in the ocean – viruses, bacteria, the small phytoplankton and microzooplankton – and the relationships between them. NIWA biological oceanographer Dr Julie Hall explains how the microbial loop forms the bottom of marine food webs and involves rapid cycling of both nutrients and carbon. The relative flow of carbon through the viral shunt and the microbial loop is a pivotal factor controlling the contribution of secondary production to the food web and to rates of nutrient remineralization and respiration. The current study examines the significance of these processes in the coastal waters of the Antarctic during the productive austral summer months. 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

7. Coined the term “Microbial Loop”Important for the recycling of organic matter and nutrients above the thermocline. 8. 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.

These molecules are too small for the average consumer but are perfect sources of fuel for bacteria. 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 in flowing waters is dependent on allochthonous sources of carbon, which vary in quality. The proportion of dissolved organic carbon (DOC) that can be degraded ranges from <1 to over 50%, and the bioavailability of DOC (micrograms bacterial biomass produced per milligram DOC present) ranges over two orders of magnitude. Microfaunal stimulation of nitrogen mineralization via the microbial loop was suggested as the main underlying mechanism (Clarholm, 1985; Griffiths, 1994; Zwart et al., 1994). Table 1.

Ron1 1Department of Molecular Microbiology & Biotechnology, Tel Aviv University, Ramat Aviv, Israel. Three microbial loop sub-model configurations were used to isolate mechanisms by which the microbial loop could influence phytoplankton biomass, considering (i) the role of bacterial mineralisation, (ii) the effect of micrograzer excretion, and (iii) bacterial ability to compete for dissolved inorganic nutrients. The microbial loop refers to the small microscopic organisms in the ocean – viruses, bacteria, the small phytoplankton and microzooplankton – and the relationships between them.

Until the late 1970s, relationships between organisms in the ocean were conceptualized as a linear food chain. Primary producers (phytoplankton) are a food source for zooplankton, the mid-trophic link with the top of the chain (fish, mammals). microbial loop in the productivity mechanisms of the oligotrophic waters since it reduces the gravitational loss of nitrogen contained in sinking organic matter. In the Antarctic waters, which generally have very high concentrations of plant nutrients sustained through physical processes, The microbial loop describes the consumption of dissolved organic matter (DOM) by bacteria, which are then grazed by protists providing a route for carbon transfer to higher trophic levels [ 1, 2 ].
