Subset

 

Morphology

Anaeroplasma

CELLULAR

Staining	Gram-negative
Morphology	Cells of young (16- to 18-h-old) cultures are coccoid, 0.5-2.0 um in diameter. Older cells have a variety of pleomorphic forms.
Motility	Nonmotile
Specialized structures	Cells are bounded by a plasma membrane only

Division

COLONIAL

Solid surface

Surface colonies have a dense center with a translucent periphery, or "fried egg" appearance. Subsurface colonies are golden, irregular and often multilobed.

Growth Parameters

Anaeroplasma

PHYSIOLOGICAL

Tropism
Oxygen	Obligately anaerobic; the inhibitory effect of oxygen on growth is not alleviated during repeated subcultures
pH	Optimum pH, 6.5-7.0.
Temperature	Optimum temperature, 37`C; no growth at 26 and 47`C.
Requirements	Require sterols for growth
Products	Strains vary in their ability to ferment various carbohydrates. The products of carbohydrate fermentation include acids (generally acetic, formic, propionic, lactic and succinic), ethanol, and gases primarily CO2, but some strains also produce H2
Enzymes
Unique features	Bacteriolytic and nonbacteriolytic strains of anaerobic mcoplasmas are described.
