AbstractBacterial lipids are well-preserved in ancient rocks and certain ones have been used as indicators of specific bacterial metabolisms or environmental conditions existing at the time of rock deposition. Here we show that an anaerobic bacterium produces 3-methylhopanoids, pentacyclic lipids previously detected only in aerobic bacteria and widely used as biomarkers for methane-oxidizing bacteria. Both Rhodopila globiformis, a phototrophic purple nonsulfur bacterium isolated from an acidic warm spring in Yellowstone, and a newly isolated Rhodopila species from a geochemically similar spring in Lassen Volcanic National Park (USA), synthesized 3-methylhopanoids and a suite of related hopanoids and contained the genes encoding the necessary biosynthetic enzymes. Our results show that 3-methylhopanoids can be produced under anoxic conditions and challenges the use of 3-methylhopanoids as biomarkers of oxic conditions in ancient rocks and as prima facie evidence that methanotrophic bacteria were active when the rocks were deposited.

Rhodopila Globiformis

Abstract Bacterial lipids are well preserved in ancient rocks and certain ones have been used as indicators of specific bacterial metabolisms or environmental conditions existing at the time of rock deposition. Here we show that an anaerobic bacterium produces 3-methylbacteriohopanepolyols (3-MeBHPs), pentacyclic lipids previously detected only in aerobic bacteria and widely used as biomarkers for methane-oxidizing bacteria. Both Rhodopila globiformis, a phototrophic purple nonsulfur bacterium isolated from an acidic warm spring in Yellowstone, and a newly isolated Rhodopila species from a geochemically similar spring in Lassen Volcanic National Park (USA), synthesized 3-MeBHPs and a suite of related BHPs and contained the genes encoding the necessary biosynthetic enzymes. Our results show that 3-MeBHPs can be produced under anoxic conditions and challenges the use of 3-MeBHPs as biomarkers of oxic conditions in ancient rocks and as prima facie evidence that methanotrophic bacteria were active when the rocks were deposited.

Rhodopila Globiformis

The genome sequence of the acidophile Rhodovastum atsumiense was determined for comparison with that of Rhodopila globiformis. Both genomes are unusually large for purple bacteria (7.10 Mb and 7.25 Mb, respectively), and they have an average nucleotide identity of 72%. This value is remarkably similar to the average nucleotide identity values for Acidisphaera, Elioraea, and Paracraurococcus, all aerobic anoxygenic phototrophs.
