Subset

 

Morphology

Thermomicrobium

CELLULAR

Staining	Gram-negative.
Morphology	Short, irregularly-shaped rods, 1.3-1.8 um in diameter and 3.0- 6.0 um in length. The pleomorphic forms are dumbbell shaped or appear irregular in diameter and occur singly or in pairs
Motility	Nonmotile.

Specialized structures

No peptidoglycan diamino acid occurs in the cell walls insignificant amounts Neither resting stages nor endospores are formed

COLONIAL

Solid surface

Colonies have a rose-pink colour.

Growth Parameters

Thermomicrobium

PHYSIOLOGICAL

Tropism	Chemoorganotrophic,
Oxygen	Obligately aerobic having a strictly respiratory type of metabolism with oxygen as the terminal electron acceptor
pH	Optimal pH 8.2=8.5, but good growth occurs between 7.5 and 8.7
Temperature	Optimum temperature for growth, 70-75`C; maximum, 80`C, minimum, 45`C.
Requirements	Maximum growth occurs on a medium consisting of yeast extract and peptone (0.5% each). Growth does not occur on glucose. n-Alkanes are not utilized
Products
Enzymes	Catalase-positive
Unique features	Generation time, 5.5 h.
