Also presented is a compilation of biochemical reactions and a list of metabolites enumerating a representative minimal metabolome of a free-living reductive chemoautotroph.
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.
This network portrays the canonical chart of autotrophic intermediary metabolism that composes the minimal metabolome of a reductive chemoautotroph. Among the different types of chemical reactions required, a sparse set of simple reactions that dominate and cause chemical transformations stepwise and advance the start compounds through intermediates to the final monomers are represented by arrows that are color-coded (see Supplemental Figure 1, at http://www.biolbull.org/supplemental/).
Because these two morphotypes were of the same general size and ultrastructure as the two types of symbionts described from other bathymodiolin mussels (Cavanaugh et al., 1987; Fisher et al., 1993; Distel et al., 1995; Fiala-Medioni et al., 2002), we refer to them herein as chemoautotrophic and methanotrophic symbiont morphotypes, or simply as chemoautotrophs and methanotrophs.
azoricus (chemoautotrophs, P = 0.115; methanotrophs, P = 0.383).
heckerae did not differ among the size-classes examined (chemoautotrophs, P = 0.67; methanotrophs, P = 0.342).
The ratio of chemoautotrophs to methanotrophs was also species-specific and independent of size class, with chemoautotrophs much more numerous than methanotrophs (13:1 to 18:1) in B.
The dominance of chemoautotrophs over methanotrophs in B.
The 25[per thousand] difference in [[delta].sup.13]C between the tissues of seep mussels and vent mussels reflects differences in the source of methane at the seep (bacterially derived; [[delta].sup.13][C.sub.methane] = -67.8[per thousand]; Paull et al., 1995, 2000) and at the vent (thermogenically derived; [[delta].sup.13][C.sub.methane] = -13.7[per thousand] to -12.7[per thousand]; Radford-Knoery et al., 1998; Charlou et al., 2002), as well as the relative contributions of methanotrophs and chemoautotrophs to mussel nutrition.
None appear to be chemoautotrophs. Molecular techniques will be the best way to investigate the links between host phylogeny and SCB distribution.
