ROOT GROWTH AND DARK FIXATION OF CARBON DIOXIDE IN CALCICOLES AND CALCIFUGES [PDF]

New Phytologist, 1969
SummaryThe inhibition of root growth by bicarbonate ions has been further investigated by an examination of the process of dark fixation of carbon dioxide by Arrhenatherum elatius and Deschampsia flexuosa. Excised roots incorporated [14C]bicarbonate mostly into malate in 4 hours. Intact plants grown on solutions containing 10 m‐equiv./1 bicarbonate for

Impact of hazardous components on CO2 biofixation from synthetic flue gas using Chlorella sp. JPR-1 in a raceway pond photobioreactor [PDF]

, 2013
This work aimed to investigate the effects of hazardous compounds (NO and SO2) in flue gas on Chlorella JPR-1 growth in a raceway pond photobioreactor at ambient temperature (30 °C) without pH control.

Nitrogen fixation by a Bangladesh deepwater rice-field calothrix [PDF]

, 1990
In order to study the influence on blue-green algal nitrogenase activity of environmental variables in deepwater rice-fields (DWR), a laboratory study was planned on a DWR isolate of Calothrix (D764).

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

New hints on nutrients dynamics and their impact on carbon sequestration in the Mediterranean Sea [PDF]

, 2009
In the World Ocean nitrogen and phosphorus cycles are deeply linked to the carbon cycle. As nitrate and phosphate play an important role in controlling biological production, the intensity of atmospheric carbon sequestration is strongly influenced by ...

Structural and biochemical insights into the thermostable esterase Ta0887 from Thermoplasma acidophilum

FEBS Open Bio, EarlyView.
In this study, a novel esterase from the thermoacidophilic archaeon Thermoplasma acidophilum was biochemically and structurally characterized. Our results demonstrate that Ta0887 is a highly thermostable esterase that preferentially hydrolyzes p‐nitrophenyl hexanoate and possesses an α‐helical cap domain that likely contributes to its substrate ...

Fixation of carbon dioxide by chemoautotrophic bacteria in grassland soil under dark conditions

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
Grassland is one of the most important terrestrial ecosystems for carbon (C) and nitrogen (N) cycling. However, while CO2 fixation by phototrophic bacteria is relatively well studied, little is known about microbial CO2 fixation without light by ...

Dark inorganic carbon fixation sustains the functioning of benthic deep‐sea ecosystems [PDF]

Global Biogeochemical Cycles, 2013
Previous studies have provided evidence that dark inorganic carbon fixation is an important process for the functioning of the ocean interior. However, its quantitative relevance and ecological significance in benthic deep‐sea ecosystems remain unknown. We investigated the rates of inorganic carbon fixation together with prokaryotic abundance, biomass,

Plasma EV Proteomics Identifies ECM Remodeling and Inflammatory Proteins LUM and C7 as Candidate Biomarkers in FSHD

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Facioscapulohumeral muscular dystrophy (FSHD) is one of the most debilitating and common muscular dystrophies. Despite its severity, no approved therapy exists for FSHD patients. However, several therapeutic candidates are currently under development, and some have recently entered clinical trials, marking the need for reliable ...

Bomb-14C analysis of ecosystem respiration reveals that peatland vegetation facilitates release of old carbon [PDF]

, 2009
The largest terrestrial-to-atmosphere carbon flux is respired CO2. However, the partitioning of soil and plant sources, understanding of contributory mechanisms, and their response to climate change are uncertain.
