Morphology

Thermus

CELLULAR

Staining	Gram- negative
Morphology	Straight rods, 0.5-0.8 um in diameter and 5.0-10.0 um in length. Filaments from 20 to more than 200 um may occur under somecultural conditions. Most strains form rotund bodies - large spheres 10-20 um in diameter - derived from the association of individual cells; such bodies are usually seen in old cultures...
Motility	Nonmotile; do not possess flagella.
Specialized structures	Most strains form yellow, orange or reddish colonies, with pigmentation due to carotenoid pigments Endospores absent

Growth Parameters

Thermus

PHYSIOLOGICAL

Tropism
Oxygen	Aerobic, having a strictly respiratory type of metabolism with oxygen as the terminal electron acceptor
pH	The optimum pH for growth is around neutrality
Temperature	Thermophilic, with an optimum temperature of 70-75`C.
Requirements
Products
Enzymes	Oxidase- and catalase-positive
Unique features	Gelatin is usually hydrolyzed. Starch is usually weakly digested. Nitrates are usually reduced to nitrites.

ENVIRONMENTAL

Habitat	Found in hot springs of neutral to alkaline pH, as well as in hot water heaters. Also found in natural waters subject to thermal pollution
