Carbon biosequestration strategies: a review

open access: yesCarbon Capture Science & Technology, 2022
Anthropogenic emissions of carbon dioxide (CO2) contribute to global warming. Limiting temperature rise requires negative emission techniques to retract the emitted CO2 from the atmosphere. Through photosynthesis, ecosystems naturally sequester and store

Comparative genomic analysis of carbon and nitrogen assimilation mechanisms in three indigenous bioleaching bacteria: predictions and validations

open access: yesBMC Genomics, 2008
Background Carbon and nitrogen fixation are essential pathways for autotrophic bacteria living in extreme environments. These bacteria can use carbon dioxide directly from the air as their sole carbon source and can use different sources of nitrogen such

Diel Patterns of Variable Fluorescence and Carbon Fixation of Picocyanobacteria Prochlorococcus-Dominated Phytoplankton in the South China Sea Basin

open access: yesFrontiers in Microbiology, 2018
The various photosynthetic apparatus and light utilization strategies of phytoplankton are among the critical factors that regulate the distribution of phytoplankton and primary productivity in the ocean.

Marine crude-oil biodegradation: a central role for interspecies interactions [PDF]

open access: yes, 2012
The marine environment is highly susceptible to pollution by petroleum, and so it is important to understand how microorganisms degrade hydrocarbons, and thereby mitigate ecosystem damage. Our understanding about the ecology, physiology, biochemistry and

Environmental impacts of grazed clover/grass pastures [PDF]

open access: yes, 2009
peer-reviwedGrazed clover/grass pastures are important for animal production systems and the clover component is critical for its contribution to N inputs via biological fixation of atmospheric N2.

Tropical carbon sink accelerated by symbiotic dinitrogen fixation

open access: yesNature Communications, 2019
The contribution of symbiotic dinitrogen fixation to the forest carbon sink could change throughout forest succession. Here the authors model nitrogen cycling and light competition between trees based on data from Panamanian forest plots, showing that ...

Ubiquitous Gammaproteobacteria dominate dark carbon fixation in coastal sediments

open access: yesThe ISME Journal, 2016
Marine sediments are the largest carbon sink on earth. Nearly half of dark carbon fixation in the oceans occurs in coastal sediments, but the microorganisms responsible are largely unknown.

Factors influencing the stable carbon isotopic composition of suspended and sinking organic matter in the coastal Antarctic sea ice environment [PDF]

open access: yes, 2011
A high resolution time-series analysis of stable carbon isotopic signatures in particulate organic carbon (&delta;<sup>13</sup>C<sub>POC</sub>) and associated biogeochemical parameters in sea ice and surface waters provides an
