Sulfate reducers, like all
chemoautotrophs, get their energy by inducing chemical reactions that transfer electrons between one molecule and another.
Analysis of the intermediaary metabolism of a reductive
chemoautotroph. Biol.
The canonical network of autotrophic intermediary metabolism: minimal metabolome of a reductive
chemoautotroph. Biol.
We have adopted this strategy in the comparative analysis of metabolic pathways for the above-mentioned organisms in order to construct the canonical metabolic chart of a reductive
chemoautotroph.
They've dated some of the natural whale falls to 70 to 80 years old, but these still bristle with
chemoautotrophs.
Osedax symbionts are heterotrophic and do not fix inorganic carbon (Goffredi et al., 2005, 2007), in contrast to
chemoautotrophs in other siboglinids (Cavanaugh et al., 1981; Southward et al., 1981, 1986; Schmaljohann and Flugel, 1987; Losekann et al., 2008).
crunogena revealed that the bacteria contain cso-type carboxysomes, like other
chemoautotrophs. However, the carboxysome polypeptide composition of T.
Carboxysomes are polyhedral protein nanocompartments found in many
chemoautotrophs and in cyanobacteria.
In each of these associations, host CA appears to increase the availability of C[O.sub.2] to the symbiont by catalytically releasing it from bicarbonate at or near the site of symbiont photosynthesis (or chemosynthesis in the case of
chemoautotrophs).
We also asked whether the relative abundance of
chemoautotrophs and methanotrophs includes an ontogenetic factor.
