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 MICROBIAL LOOP This important part of marine food chains involves DOM leaked from diatoms and other phytoplanktons that is consumed by bacteria. The bacteria are then consumed by flagellates and ciliates. These members of the plankton also leak DOM that is in turn absorbed by the bacteria.
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. 2007) could play an important role in the productivity of the 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.

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

the microbial loop can play an important role in reducing the total organic carbon (TOC) in drainage water from an oil terminal facility. Drainage water forms whenever crude oil is allowed to stand. The water originates from the drilling process and transportation via oil tankers and slowly settles to the bottom of storage tanks.

Consequently, beneficial effects of protozoa on plant growth have been assigned to nutrients released from consumed bacterial biomass, that is, the ‘microbial loop’.
