Characterisation of cytochrome c MtoD from the iron-oxidising autotroph sideroxydans lithotrophicus ES-1
Despite the discovery of iron-oxidising microorganisms as early as 1836 by Ehrenberg, as described by Harder in 1919, iron-oxidising lithotrophs and their respiratory pathways remain poorly understood. The neutrophilic iron-oxidiser Sideroxydans lithotrophicus ES-1 contains a conserved mtoDAB gene …

Freshwater Invertebrate Assimilation Nutrients from Detrital Biofilms Under Light and Phosphorus Manipulation
… biofilm constituents (i.e heterotroph and autotroph) contribute C and P to detritivore nutrition under raised light and nutrient regimes. I conducted a feeding study using detritivorous caddisflies (i.e. <em>Pycnopsyche </em>sp.) and conditioned leaf litter across a fully-factorial …

Autotrophe CO2-Fixierung in thermophilen Mikroorganismen
… vier verschiedene Stoffwechselwege zur autotrophen CO2-Fixierung bekannt. Dies sind der Calvin-Zyklus, der reduktive Citrat-Zyklus, der reduktive Acetyl-CoA-Weg und der 3-Hydroxypropionat-Zyklus. Letzterer wurde bisher nur im phototrophen Bakterium Chloroflexus aurantiacus nachgewiesen. …

Zur Struktur und Funktion regulatorischer Elemente des cbb-Regulons in Ralstonia eutropha
Für die autotrophe Assimilation von CO2 benötigt Ralstonia eutropha H16 die Enzyme des Calvin-Cyclus. Die genetische Kontrolle bei der wechselseitigen Umstellung des Kohlenstoffmetabolismus zwischen autotrophen und heterotrophen Bedingungen betrifft vorrangig die Transkription der cbb-Operone, …

Effects of artificial light at night on benthic primary producers in freshwaters
… it increased the proportion of the dominant autotroph group, the diatoms and decreased the proportion of cya-nobacteria in early developmental stages, but indicated a decreased proportion of diatoms and an increased proportion of cyanobacteria in the later developmental stages. I found that …

Dynamics of baseline stable isotopes within a temperate coastal ecosystem: Relationships and projections using physical and biogeochemical factors
… at or near the base of the food web (e.g. autotrophs and their consumers), which act as basal reference points from which to calibrate inferences. Therefore, understanding variations in isotopic baselines, and the mechanisms leading to their variability, is crucial for food web ecology. …
