Abstract
Stable carbon isotope fractionations between dissolved inorganic carbon and lipid biomarkers suggest
photoautotrophy by Chloroflexus-like organisms in sulfidic and nonsulfidic Yellowstone hot springs. Where
co-occurring, cyanobacteria appear to cross-feed Chloroflexus-like organisms supporting photoheterotrophy as
well, although the relatively small 13C fractionation associated with cyanobacterial sugar biosynthesis may
sometimes obscure this process.
