High dark carbon fixation in the tropical South China Sea

Continental Shelf Research, 2017
Abstract Dark carbon fixation (DCF) has been usually assumed to be insignificant in the study of microbial production and carbon cycling. In order to evaluate DCF distribution and its contribution to biogenic carbon flux, surface and vertical distribution of DCF, primary production (PP) and bacterial production (BP) were investigated in both offshore

Dark carbon fixation and chemolithotrophic microbial community in surface sediments of the cascade reservoirs, Southwest China

Science of the Total Environment, 2020
Dark carbon fixation (DCF) by chemolithotrophic microbes can make considerable contribution to inorganic carbon fixation in aquatic ecosystems. However, little is known about the importance and diversity of chemolithotrophic microbes in cascade reservoir

Active dark carbon fixation evidenced by 14C isotope assimilation and metagenomic data across the estuarine-coastal continuum

Science of the Total Environment
Estuaries, as important land-ocean transitional zones across the Earth's surface, are hotspots of microbially driven dark carbon fixation (DCF), yet understanding of DCF process remains limited across the estuarine-coastal continuum.

Major role of nitrite-oxidizing bacteria in dark ocean carbon fixation

Science, 2017
Dissolved inorganic carbon fixers revealed Most of the ocean is dark. Yet it is in this darkness, away from photosynthesizing sunlight, that most planetary carbon cycling occurs. Pachiadaki et al.

Carbohydrate Reserve and Dark Carbon Fixation in the Brown Macroalga, Laminaria hyperborea.

Journal of Plant Physiology, 1984
Tissue discs originating from young, growing blade areas and from adult, mature frond regions of the brown macroalga Laminaria hyperborea (Fosl.) Gunn. (Phaeophyceae, Laminariales) were investigated with particular regard to photosynthesis, dark respiration, dark carbon fixation, and carbohydrate reserves.

Variance in bacterial communities, potential bacterial carbon sequestration and nitrogen fixation between light and dark conditions under elevated CO2 in mine tailings

Science of the Total Environment, 2019
This study is the first to show the response of bacterial communities with primary carbon and nitrogen fixers to elevated CO2 (eCO2) in light and dark conditions based on 6 months of culture growth.

Microbial carbon fixation and its influencing factors in saline lake water.

Science of the Total Environment, 2023
Microbial carbon fixation in saline lakes constitutes an important part of the global lacustrine carbon budget. However, the microbial inorganic carbon uptake rates in saline lake water and its influencing factors are still not fully understood. Here, we
