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.
Bacterial nutrient uptake also implies that bacterivorous protozoa may play a pivotal role in the remineralization of these elements in the microbial loop. Jan 11, 2021 contains the components of the 'microbial loop', namely phytoplankton, picophytoplankton, bacterio- plankton, microzooplankton, dissolved Nov 10, 2020 ABSTRACT: In an attempt to quantify the organic fluxes within the microbial loop of oligotrophic. Mediterranean water, organic pools and Zooplankton activity may play a key role in providing organic substrate for bacterial growth. The significance of the microbial loop in aquatic food webs has Modern view of the pelagic food web, emphasizing the microbial loop as a major path for organic matter flux. Competition between the three main flux paths— Mar 6, 2012 The microbial loop refers to the small microscopic organisms in the ocean – viruses, bacteria, the small phytoplankton and microzooplankton The recycling of organic material through bacteria and microzooplankton to higher trophic levels, known as the “microbial loop”, is an important process in aquatic Plankton community structure and major pools and fluxes of carbon were observed before and after culmination of a bloom of cyanobacteria in eutrophic The microbial loop describes a trophic pathway where, in aquatic systems, dissolved organic carbon (DOC) is returned to higher trophic levels via its Jul 1, 2006 Microbial Loop http://hahana.soest.hawa ii.e d u/agouroninstitutecourse.

Lee; The Microbial Loop: Sink or Link, BioScience, Volume 43, Issue 3, 1 March 1993, Pages 180–181, https://doi.org/10.2307/1312031 In the microbial loop hypothesis, the increasing predation by protozoa and nematodes on the increased microbial biomass accelerate the turnover of microbial organic nitrogen and liberate ammonium 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. Effects of protozoa and nematodes on plant biomass production, and total plant and shoot nitrogen contents The abundance of viral-like particles in marine ecosystems ranges from <104 ml−1 to >108 ml−1. Their distribution in time and space parallels that of other biological parameters such as bacterial abundance and chlorophyll a. There is a lack of consensus between methods used to assess viral activity, i.e., rate of change in viral abundance (increase or decrease).
In the microbial loop hypothesis, the increasing predation by protozoa and nematodes on the increased microbial biomass accelerate the turnover of microbial organic nitrogen and liberate ammonium

Resource availability influences marine microbial community structure, suggesting that population-specific resource partitioning defines discrete niches. Identifying how resources are partitioned
To date the origin of such recalcitrant DOC (RDOC) is unclear. A recently proposed conceptual framework, the microbial carbon pump (MCP), emphasizes the microbial transformation of organic Resource availability influences marine microbial community structure, suggesting that population-specific resource partitioning defines discrete niches.

A recently proposed conceptual framework, the microbial carbon pump (MCP), emphasizes the microbial transformation of organic Resource availability influences marine microbial community structure, suggesting that population-specific resource partitioning defines discrete niches. Identifying how resources are partitioned 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]. The grazing step is mediated primarily by heterotrophic nanoﬂagellates (HNFs) which are the key bacteriovores in aquatic environments .
