Microbial Extracellular Enzymes and the Marine Carbon Cycle

Annual Review of Marine Science, 2011
Extracellular enzymes initiate microbial remineralization of organic matter by hydrolyzing substrates to sizes sufficiently small to be transported across cell membranes. As much of marine primary productivity is processed by heterotrophic microbes, the substrate specificities of extracellular enzymes, the rates at which they function in seawater and ...

Implications of plastic pollution on global marine carbon cycling and climate

Emerging Topics in Life Sciences, 2022
Plastic pollution can both chemically and physically impede marine biota. But it can also provide novel substrates for colonization, and its leachate might stimulate phytoplankton growth. Plastic contains carbon, which is released into the environment upon breakdown.

Marine biopolymer self-assembly: implications for carbon cycling in the ocean

Faraday Discussions, 2008
Dissolved organic matter is the largest reservoir of reduced carbon in the ocean and is primarily composed of small biopolymers. It is a critical substrate for the microbial community and plays a pivotal role in global carbon cycling.

Cycling of Organic Carbon in a Coastal Marine System

1986
A carbon (C) budget in terms of input to the sediment, degradation of organic matter in surficial sediments, and accumulation in the sediment column was constructed for a representative area in the Kiel Bight. A transect of six stations was used to include both vertical and horizontal transport rates.

Role of the marine biosphere in the global carbon cycle

Limnology and Oceanography, 1991
The geochemical disequilibrium of our planet is due mainly to carbon sequestration by marine organisms over geological time. Changes in atmospheric CO, during interglacial-glacial transitions require biological sequestration of carbon in the oceans.

Effects of the Marine Biota on Global Carbon Cycling

1993
Natural carbon cycling in the global ocean and its influence on atmospheric CO2 concentrations can be examined conveniently in terms of a solubility pump, an organic carbon pump and a calcium carbonate pump (Volk and Hoffert 1985). Here a review is presented of the physical, chemical and biological processes which determine the strength of these pumps.
