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’.

Transformational Power Instead of sunlight, specialized organisms can obtain energy through chemical reactions, a process called chemosynthesis. 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 1. The Microbial Loop 2. Lawrence R. Pomeroy ODUM School of Ecology , University of GeorgiaThe Ocean’s Food Web, A Changing Paradigm 1974 3.

That trophic pathway is called loop because it expresses the return of dissolved organic matter to higher trophic levels via its incorporation into bacterial biomass. The microbial loop is of particular importance in increasing the efficiency of the marine food web via the utilization of dissolved organic matter (DOM), which is typically unavailable to most marine organisms.

1984, Bratbak & Thingstad 1985, Fasham 1985, Frost 1987). The approach taken in this paper differs from these in that it concentrates on analysis of steady- 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 assumed mechanism, known as the ‘microbial loop in soil’ (Clarholm, 1985), is triggered by the release of root exudates from plants that increase bacterial growth in the rhizosphere. Plant available nutrients will be strongly sequestered during microbial growth microbial loop in a sentence - Use "microbial loop" in a sentence 1. This patch formation affects the biologically-mediated transfer of matter and energy in the microbial loop.

Microbial loop. The microbial loop acts as a pathway and connection between different relationships in an ecosystem. The microbial loop connects the pool of DOM to the rest of the food web, specifically various microorganisms in the water column. This allows for constant cycling of this dissolved organic matter.

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’. The microbial loop is a trophic pathway in the marine microbial food web. Picoplankton also form the base of aquatic microbial food webs and are an energy source in the microbial loop. A significant portion of this picoplankton (<1 μm) production may be consumed by heterotrophic protozoans in a "microbial loop." The microbial loop is based on micro-interactions between different trophic levels of microbes and organisms. When nutrients enter the microbial loop, they tend to remain in the photic zone longer, due to the location, and slow sinking rates of microbes.
