Methane-dependent growth of Crenothrix in Lake Rotsee

Summary

[edit]
Description
English: Methane-dependent growth of Crenothrix in Lake Rotsee.
(a) Crenothrix in the Lake Rotsee oxic incubation visualized by CARD-FISH (green; counterstained by DAPI in blue) with a specific probe Creno445 (Stoecker et al., 2006). A small coccoid cell targeted by the probe (marked by the asterisk) might represent a gonidial cell, which Crenothrix is reportedly capable of producing (Völker et al., 1977).
(b) The corresponding 13C/12C nanoSIMS image shows homogeneous 13C enrichment throughout the cell filament. The small coccoid cell is also significantly enriched, albeit less.
(c) The corresponding 32S/12C nanoSIMS image showing distribution of organic material on the filter.

Note from the Uploader: Bacteria involved may be members of a sister genus of Crenothrix (within the same family), e. g. Crenothrix sp. D3 (NCBI) syn. UBA4132 sp002134785 (GTDB). Other gamma-MOB genera found in Lake Zug besides UBA4132 include SXIZ01, UBA10906, and Methylobacter_C (GTDB) syn. KS41.
