Fractionation of Stable Carbon Isotopes during Chemoautotrophic Growth of Sulfur-Oxidizing Bacteria †

Ruby, Edward G.
RESUMO
Laboratory-grown strains of chemoautotrophic Thiomicrospira sp. strain L-12 and Thiobacillus neapolitanus produced cell carbon that was 24.6 to 25.1 ppt (24.6 to 25.1 mg/g) lower in 13C isotope abundance than the ambient source of carbon dioxide and bicarbonate. This degree of 13C isotope depletion was comparable to that found in organic material produced in deep-sea hydrothermal-vent communities.
