Thermophilic Cyanobacteria

Mickey Springs Sample #8

Mickey Springs sample #8 was collected from the outflow channel of a glorie hole (at approx. 100 C).  The mat was growing in the 50-70 C range. The mat includes orange to red surficial layer as well as a dark green filamentous growth in patches.

 
 
 

Short (<30 cell) filaments bundled to form strands of an Anabaena-like cyanobacterium.  Imaged at 1000x oil, phase-2.
 

Very small filament, approximately .5 mm in diameter.  Diatoms were seen rarely.  The diatom in this image is 7 mm wide.  Imaged at 1000x oil, phase-2.
 

Coccoid cyanobacterium with encapsulated cell packets.  Probably Cyanothece minervae.   Cells are approximately 3-4 mm in diameter.  Imaged at 1000x oil, phase-2.
