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.
Autotrophs are of two general types: photoautotrophs (photolithotrophs) whose energy is derived from sunlight, and chemoautotrophs or chemolithotrophs, which obtain energy for growth and reproduction from oxidation of inorganic materials.
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).

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.
