Morphology Rod shaped or pleomorphic. Rods are generally 0.6-0.8 um wide and 1.6-1.9 um long. Elongated, flexuous filaments may be formed under certain conditions..
Motility Motile by 4-7 unsheathed lateral or polar flagella
Specialized structures nonsporing

Growth Parameters Halomonas
PHYSIOLOGICAL  
Tropism Chemoorganotrophic. Carbohydrates, amino acids and some polyols can serve as sole casrbon sources in mineral media. Ammonium sulfate can serve as a sole nitrogen source.
Oxygen Possess mainly a respiratory type of metabolism with oxygen as the terminal electron acceptor; growth can occur anaerobically with nitrate. Growth on glucose can occur under anerobic conditions in the absence of nitrate, indicating some fermentative ability; however, anerobic growth iwth other carbohydrates or with amino acids requires the presence of nitrate
pH  
Temperature  
Requirements  
Products Nitrate is reduced to nitrite
Enzymes Catalase- and oxidase-positive
Unique features  
ENVIRONMENTAL  
Habitat Halotolerant, able to grow in NaCl concentrations ranging from 0.1-32.5% (w/v). Isolated from a solar salt facility, but may inhabit intertidal areas and saline lakes.
