Morphology Methanomicrobium mobile
CELLULAR  
Staining Gram-negative
Morphology Short, straight to slightly curved, irregular rods, 0.6-0.7 um wide and 1.5-1.5 um long, with rounded ends. Morphology may be influenced by substrate availability, becoming coccoid (0.5-1.0 um in diameter) under starvation conditions. Cells occur singly, in pairs but not in chains
Motility Species may be motile, with monotrichous polar flagellation, or nonmotile
Specialized structures . Capsules are not formed. Endospores are not produced.

Growth Parameters Methanomicrobium mobile
PHYSIOLOGICAL  
Tropism  
Oxygen Strictly anaerobic
pH Growth and methanogenesis occur from pH 5.9 to 7.7 with an optimum between 6.1 and 7.0.
Temperature Growth between 25 and 45`C with an optimum at about 40`C.
Requirements Acetate is a required nutrient. Species may have no other requirements for organic nutrients or may have several.
Products Hydrogen-carbon dioxide serves as substrate for methanogenesis and growth: One of the two known species also uses formate
