| The following description of the Thermobacteria came from Brock et al. (1994), Margulis and Schwartz (1998), Garrity et al. (2001 and 2003), and Black (2002). |
- I. SYNONYMS: Thermoacidophilic bacteria, archaebacterial mycoplasmas.
- II. PHYLUM CHARACTERISTICS:
- A. Structure
- Cell Form: Coccoid (text with tooltip) A coccus (cocci, pl.) is a spherical cell form. , and variable
- Cell Wall: Variable Gram + (text with tooltip) A Gram + cell retains the blue-black crystal-violet color following destaining with alcohol during the Gram Stain procedure. and Gram – (text with tooltip) A Gram - cell loses the blue-black crystal-violet color following destaining with alcohol during the Gram Stain procedure. Then, it takes on the color of the counterstain, typically iodine. .
- Motility: Motile (text with tooltip) A motile cell moves by means of flagella. or non-motile.
- B. Physiology
- O2 Tolerance: Strict anaerobes.
- Substrates: Many sulfur compounds; carbon dioxide and hydrogen in Methanopyrus.
- Products: Hydrogen sulfide and elemental sulfur; methane in Methanopyrus.
- C. Other:
- D. Ecology: Grow at neutral pH above 80C. Methanopyrus freezes below 80C.
