For Clostridium ljungdahlii, the RNF complex plays a key role for energy conversion from gaseous substrates such as hydrogen and carbon dioxide. In a previous study, a disruption of RNF-complex genes led to the loss of autotrophy, while heterotrophy was ...

Relative Diazotroph Abundance in Symbiotic Red Sea Corals Decreases With Water Depth
Microbial dinitrogen (N2) fixation (diazotrophy) is a trait critical for coral holobiont functioning. The contribution of N2 fixation to holobiont nitrogen (N) supply likely depends on the ecological niche of the coral holobiont.

The response of the Mediterranean gorgonian Eunicella singularis to thermal stress is independent of its nutritional regime. [PDF]
Over the last few decades, sessile benthic organisms from the Mediterranean Sea have suffered from the global warming of the world's oceans, and several mass mortality events were observed during warm summers.

A challenge for 21st century molecular biology and biochemistry: what are the causes of obligate autotrophy and methanotrophy? [PDF]
We assess the use to which bioinformatics in the form of bacterial genome sequences, functional gene probes and the protein sequence databases can be applied to hypotheses about obligate autotrophy in eubacteria.

Comparison of polyhydroxybutyrate content produced by Spirulina sp. under conditions of autotraphic, heterotrophic and mixotrophic cultures [PDF]
Polyhydroxybutyrate is one of the biodegradable compounds which is produced by cyanobacteria Spirulina sp. In this study, cyanobacteria Spirulina sp isolated from water reservoirs of Guilan province were cultured in Zarrouk medium for 20 days and were ...

Modest net autotrophy in the oligotrophic ocean [PDF]
AbstractThe metabolic state of the oligotrophic subtropical ocean has long been debated. Net community production (NCP) represents the balance of autotrophic carbon fixation with heterotrophic respiration. Many in vitro NCP estimates based on oxygen incubation methods and the corresponding scaling relationships used to predict the ecosystem metabolic ...

Nitrogen Fixation Aligns with nifH Abundance and Expression in Two Coral Trophic Functional Groups
Microbial nitrogen fixation (diazotrophy) is a functional trait widely associated with tropical reef-building (scleractinian) corals. While the integral role of nitrogen fixation in coral nutrient dynamics is recognized, its ecological significance ...

PRO AND CONTRA OF K.E. TSIOLKOVSKY’S «AUTOTROPHY»
«Автотрофные» размышления К.Э. Циолковского рассмотрены в связи с подменой субъектной матрицы понимания человека, общества и человечества индивидной. Доказано: 1) в «космической философии» есть место двум версиям интерпретации общественного, сопряжённым ...
