The Presence of an Endogenous Respiration in the Autotrophic Bacteria
It is shown that there exists in the autotrophic bacterium Thiobacillus thiooxidans a measurable oxygen uptake in the absence of the specific nutrient (sulfur). This respiration is shown to be due to the utilization of organic materials which must have been previously synthesized by the chemosynthetic process, providing evidence that autotrophic bacteria contain a dissimilatory process which in...
متن کاملAutotrophic nitrogen assimilation and carbon capture for microbial protein production by a novel enrichment of hydrogen-oxidizing bacteria.
Domestic used water treatment systems are currently predominantly based on conventional resource inefficient treatment processes. While resource recovery is gaining momentum it lacks high value end-products which can be efficiently marketed. Microbial protein production offers a valid and promising alternative by upgrading low value recovered resources into high quality feed and also food. In t...
متن کاملAssimilation of carbon dioxide by hydrogen bacteria.
Autotrophic organisms can use carbon dioxide as their sole source of carbon. Within this group, the chemosynthetic bacteria secure energy for carbon dioxide assimilation by the oxidation of simple inorganic substances, although the photosynthetic organisms obtain this energy from light. The phylogenetic relationships of the chemosynthetic bacteria to the photosynthetic and to the heterotrophic ...
متن کاملGenomic signatures of fifth autotrophic carbon assimilation pathway in bathypelagic Crenarchaeota
Marine Crenarchaeota, ubiquitous and abundant organisms in the oceans worldwide, remain metabolically uncharacterized, largely due to their low cultivability. Identification of candidate genes for bicarbonate fixation pathway in the Cenarchaeum symbiosum A was an initial step in understanding the physiology and ecology of marine Crenarchaeota. Recent cultivation and genome sequencing of obligat...
متن کاملForest annual carbon cost: a global-scale analysis of autotrophic respiration.
Forest autotrophic respiration (R(a)) plays an important role in the carbon balance of forest ecosystems. However, its drivers at the global scale are not well known. Based on a global forest database, we explore the relationships of annual R(a) with mean annual temperature (MAT) and biotic factors including net primary productivity (NPP), total biomass, stand age, mean tree height, and maximum...
