Morphology Thermotoga
Staining Gram negative
Morphology ods (0.6 x 1.5-11.0 um) surrounded by a sheath- like structures ballooning over the ends of the cell.
Motility nonmotile or motile by polar, lateral or peritrichous flagella
Specialized structures no spores
Solid surface  


Growth Parameters Thermotoga
Tropism chemoorganotrophic
Oxygen anaerobe
Temperature thermophilic, optimum temperature is 70-80 oC growth occurs at temperatures as high as 90 oC
Requirements Hydrogen is inhibitory and inhibition is overcome by the addition of sulfur with the formation of H2S
Products metabolize carbohydrates, tryptone, or yeast extract. Fermentation products are mainly lactate, acetate, CO2 and H2
Unique features Marine strains will grow in 3.75% NaCl
Habitat isolated from geothermally heated marine sediments or hot springs
