Microbial loop carbon cycling in ocean environments studied The aquatic food linkage between heterotrophic bacteria and protists is so-called “microbial loop”, functioning as important matter cycling in pelagic food webs of Microbial Insights is a cutting-edge environmental biotechnology testing lab.

The microbial loop describes a trophic pathway where, in aquatic systems, dissolved organic carbon (DOC) is returned to higher trophic levels via its

microorganisms in the ‘microbial loop’. They lead to a number of formalizations of their various roles over the next few decades, and thus a clearer under-standing of the activities of ‘ecological groups’ or ‘guilds’ of microbial taxa (Sieburthet al., 1978; Azam et al., 1983; Fenchel, 1988; Sherr et al., 1988; Answering Charles Darwin’s prescient question has taken us nearly two centuries. Only in recent decades have methods and concepts been developed to explore the significance of microbes in the ocean’s web of life.

Last Updated on Wed, 06 Jan 2021 | Marine Ecology. In the marine ecosystem the foregoing elementary account of the organic food cycle must be extended to take account of the significance of dissolved organic matter (DOM) in seawater. The microbial loop is a marine trophic pathway which incorporates dissolved organic carbon into the food chain.. 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 2013-05-08 [The microbial loop in the planktonic communities in lakes with various trophic status].

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.

It is estimated that 60 percent of the energy flowing through marine food chains passes through the microbial loop The microbial loop is the conventional model by which nutrients and minerals are recycled in aquatic eco-systems. Biochemical pathways in different organisms become metabolically inter-connected such that nutrients are utilized, processed, released and re-utilized by others. The microbial loop is so important, scientists view it as the microbes’ most essential ecological role. Transformational Power Instead of sunlight, specialized organisms can obtain energy through chemical reactions, a process called chemosynthesis. Coined the term “Microbial Loop”Important for the recycling of organic matter and nutrients above the thermocline 8.

The microbial loop is known as the pathway for dissolved organic matter (DOM) through the bacterial and microzooplankton communities to higher trophic levels. This pathway is considered important for carbon and nitrogen transport in the pelagic environment (Azam et al., 1983). The microbial loop refers to the small microscopic organisms in the ocean – viruses, bacteria, the small phytoplankton and microzooplankton – and the relationships between them. The isotopic character of SPOM and the presence of ciliates suggest that a pelagic microbial loop (Azam et al. 1983, Pomeroy et al.
