Morphology

Beijerinckia

CELLULAR

Staining	Gram-negative
Morphology	Straight or slightly curved rods, 0.5-1.5 um in diameter and 1.7-4.5 um in length, with rounded ends. Occur singly Sometimes large, misshapen cells 3.0 x 5.0-6.0 um occur; these are occasionally branched or forked.
Motility	Motile by peritrichous flagella or nonmotile.
Specialized structures	Large, highly-refractile, intracellular granules of poly-B-hydroxybutyrate occur, generally one at each pole. Cysts (enclosing one cell) and capsules (enclosing several cells) occur in some species..

Division

COLONIAL

Solid surface

On agar media, especially under N2-fixing conditions, copiou stenacious and elastic slime is produced and giant colonies develop with a smooth, folded, or plicated surface; some strains form slime having a more granular consistency similar to that formed by Azotobacter.

Liquid

In liquid media no surface pellicle is formed, but the whole medium becomes a homogeneous, highly viscous, semitransparent mass; in some species the whole medium becomes opalescent and turbid, and adhering slime is not produced.

 

Growth Parameters

Beijerinckia

PHYSIOLOGICAL

Tropism
Oxygen	Aerobic, having a strictly respiratory type of metabolism with oxygen as the terminal electron acceptor. Molecular nitrogen is fixed under aerobic conditions and also under decreased oxygen pressures
pH	Growth occurs between pH 3.0 and pH 9.5- 10.0.
Temperature	Optimum temperature, 20-30`C; no growth occurs at 37`C
Requirements	Glucose, fructose, and sucrose are utilized by all strains and are oxidized to CO2 and a small amount of acetic acid. No growth occurs on peptone agar or in peptone broth. Glutamate is utilized poorly or not at all..
