Figure 1

Representative TEM images of bacterial cells (ba), EPS (eps), virus-like particles (v), and neoformed minerals (m), in the biofilms covering the active depositional surface of travertines in the following sites: (A) Pamukkale; (B) Egerszalók; (C) Terme di Saturnia; (D) Bullicame. Note that the shape of the capsids (80–300 nm in size) varies from hexagonal (white arrows) to subspherical (dark arrows). Mineralization of organic substrates is variable and mainly in the EPS and on viruses with aggregates of nanocrystals (dashed arrows).
