Morphology Azomonas
CELLULAR  
Staining Gram-negative, sometimes Gram-variable
Morphology Cells 2.0 um or more in diameter and of various lengths, rangingfrom rods to ovoid to coccoid in shape. Occur singly, in pairsor in clumps. Pleomorphism is generally present.
Motility Motile by peritrichous or polar flagella.
Specialized structures Do not produce endospores or cysts
Division  
COLONIAL  
Solid surface Water-soluble pigments and fluorescent pigments are produced by nearly all strains
Liquid  

 

Growth Parameters Azomonas
PHYSIOLOGICAL  
Tropism Chemoorganotrophic, using sugars, alcohols and the salts of organic acids for growth. Nitrogen fixers; generally fix nonsymbiotically at least 10 mg of molecular nigrogen/g of carbohydrate (usually glucose) consumed
Oxygen Aerobic, but can also grow under decreased oxygen tensions.
pH The optimum pH for nitrogen fixation is close to neurtrality, but certain strains can also fix nitrogen at a pH of 4.6-4.8
Temperature  
Requirements Molybdenum is required for nitrogen fixation

Can utilize ammonium salts and certain amino acids as sources of nitrogen...
