Carbon fixation from mineral carbonates

Nature Communications, 2017
Evidence showing that carbonates can directly supply CO2 for autotrophy is lacking. Here, using stable isotope analyses and NanoSIMS imaging, the authors show that a model euendolith, Mastigocoleus testarum strain BC008, derives the majority of its ...

Metagenomic insights into S(0) precipitation in a terrestrial subsurface lithoautotrophic ecosystem

Frontiers in Microbiology, 2015
The Frasassi and Acquasanta Terme cave systems in Italy host isolated lithoautotrophic ecosystems characterized by sulfur-oxidizing biofilms with up to 50% S(0) by mass.

Remobilization of seed phosphorus reserves and their role in attaining phosphorus autotrophy in maize (Zea mays L.) seedlings

, 2014
International audienceSuccessful remobilization of seed reserves is the driving force behind seedling establishment for maximum final crop outcomes. The remobilization of stored maize seed phosphorus (P), and its allocation towards growing seedlings is ...

Autotrophic vs. heterotrophic microalgae: Juxtaposition of performances in treating organic-rich effluent

Desalination and Water Treatment
Microalgae-based wastewater treatment is an alternative to physico-chemical and bacteria-based technologies. Microalgae-based wastewater treatment showed enormous potential, not only exhibiting excellent pollutant removal efficiencies but also unlimited ...

Evidence of coupled autotrophy and heterotrophy on plastic biofilms and its influence on surrounding seawater

, 2022
International audienceWe measured phytoplankton primary production and heterotrophic bacterial activities on microplastics and seawater in the Northwestern Mediterranean Sea during two 3-month spring periods over 2 consecutive years.

Contribution of Crenarchaeota and Bacteria to autotrophy in the North Atlantic interior

, 2011
Marine Crenarchaeota are among the most abundant groups of prokaryotes in the ocean and recent reports suggest that they oxidize ammonia as an energy source and inorganic carbon as carbon source, while other studies indicate that Crenarchaeota use ...

Net community production of oxygen derived from in vitro and in situ 1-D modeling techniques in a cyclonic mesoscale eddy in the Sargasso Sea [PDF]

Biogeosciences, 2009
It has been proposed that the disagreement traditionally reported between in vitro incubation and in situ estimates of oxygen net community production (NCP) could be explained, at least partially, by undersampling episodic pulses of net autotrophy ...

Quantifying archaeal community autotrophy in the mesopelagic ocean using natural radiocarbon [PDF]

, 2006
An ammonia-oxidizing, carbon-fixing archaeon, Candidatus “Nitrosopumilus maritimus,” recently was isolated from a salt-water aquarium, definitively confirming that chemoautotrophy exists among the marine archaea.

Transcriptome analysis reveals the molecular mechanism of differences in growth between photoautotrophy and heterotrophy in Chlamydomonas reinhardtii

Frontiers in Plant Science
BackgroundThe green alga Chlamydomonas reinhardtii can grow photoautotrophically utilizing light and CO2, and heterotrophically utilizing acetate. The physiological and biochemical responses of autotrophy and heterotrophy are different in C. reinhardtii.
