FIG 2.

Morphology of strain MY2, based on FISH, TEM, and SEM analyses. (A) Merged image with a Cy3-labeled Archaea-specific probe (Arc915; red) and a FAM-labeled Bacteria-specific probe (EUB338; green). (B) Merged image with a Cy3-labeled Archaea-specific probe (Arc915) and DAPI. Magenta indicates the archaeal cells. (C) Transmission electron micrograph of strain MY2. The arrows indicate the archaeal flagella. (D) Scanning electron micrograph of strain MY2 cells. (E) Transmission electron micrograph of ultrathin section of strain MY2 cells.
