Chemoautotrophic growth of ammonia-oxidizing Thaumarchaeota enriched from a pelagic redox gradient in the Baltic Sea [PDF]

Frontiers in Microbiology, 2015
Ammonia-oxidizing archaea (AOA) are an important component of the planktonic community in aquatic habitats, linking nitrogen and carbon cycles through nitrification and carbon fixation.

Characterize the Growth and Metabolism of Acidithiobacillus ferrooxidans under Electroautotrophic and Chemoautotrophic Conditions [PDF]

Microorganisms
Acidophiles are capable of surviving in extreme environments with low pH. Acidithiobacillus ferrooxidans is a typical acidophilic bacterium that has been extensively studied when grown chemoautotrophically, i.e., when it derives energy from oxidation of ...

Whole-genome transcriptional profiling of Bradyrhizobium japonicum during chemoautotrophic growth. [PDF]

J Bacteriol, 2008
ABSTRACT Bradyrhizobium japonicum is a facultative chemoautotroph capable of utilizing hydrogen gas as an electron donor in a respiratory chain terminated by oxygen to provide energy for cellular processes and carbon dioxide assimilation via a reductive pentose phosphate pathway. A transcriptomic analysis of

The genome-scale metabolic model for the purple non-sulfur bacterium Rhodopseudomonas palustris Bis A53 accurately predicts phenotypes under chemoheterotrophic, chemoautotrophic, photoheterotrophic, and photoautotrophic growth conditions. [PDF]

PLoS Computational Biology, 2023
The purple non-sulfur bacterium Rhodopseudomonas palustris is recognized as a critical microorganism in the nitrogen and carbon cycle and one of the most common members in wastewater treatment communities.

Metabolic biochemical models of N2 fixation for sulfide oxidizers, methanogens, and methanotrophs [PDF]

mSystems
Dinitrogen (N2) fixation provides bioavailable nitrogen to the biosphere. However, in some habitats (e.g., sediments), the metabolic pathways of organisms carrying out N2 fixation are unclear. We present metabolic models representing various chemotrophic

Chemoautotrophic production of gaseous hydrocarbons, bioplastics and osmolytes by a novel Halomonas species [PDF]

Biotechnology for Biofuels and Bioproducts, 2023
Background Production of relatively low value, bulk commodity chemicals and fuels by microbial species requires a step-change in approach to decrease the capital and operational costs associated with scaled fermentation. The utilisation of the robust and

The Effects of Predominantly Chemoautotrophic Versus Heterotrophic Biofloc Systems on Nitrifying Bacteria, Planktonic Microorganisms, and Growth of Penaeus vannamei, and Oreochromis niloticus in an Integrated Multitrophic Culture

Fishes
The aim of this study was to evaluate the effect of predominantly chemoautotrophic and heterotrophic biofloc systems on ammonia-oxidizing bacteria (AOB), nitrite-oxidizing bacteria (NOB), and planktonic microorganisms in an integrated Penaeus vannamei ...

Tilapia nursery stocking densities in a chemoautotrophic biofloc system [PDF]

Ciência e Agrotecnologia, 2022
The nursery phase in tilapia using biofloc technology is important as it increases the predictability of production. However, none studies evaluating the stocking densities of tilapia focused only on the use of an inorganic carbon source to promote the ...

Main components of free organic carbon generated by obligate chemoautotrophic bacteria that inhibit their CO2 fixation

iScience, 2022
Summary: Chemoautotrophic bacteria play an important role in combating the rise in global CO2. However, recently it was found that extracellular free organic carbon (EFOC) generated by chemoautotrophic bacteria inhibits their CO2 fixation.

Chemoautotrophic carbon fixation rates and active bacterial communities in intertidal marine sediments. [PDF]

PLoS ONE, 2014
Chemoautotrophy has been little studied in typical coastal marine sediments, but may be an important component of carbon recycling as intense anaerobic mineralization processes in these sediments lead to accumulation of high amounts of reduced compounds,
