Growth Parameters Psychrobacter immobilis
PHYSIOLOGICAL  
Tropism chemoorganotroph
Oxygen  
pH  
Temperature most are psychrotrophic. optimum 20 oC, can grow at 5oC but not at 35-37 oC. Strains that grow at 35-37 oC do not grow at 5oC
Requirements  
Products most strains produce acid from glucose and other sugars, phenylalanine and tryptophan can be deaminated. Nitrate reduced. Tween 80 hydrolysed. Acid not formed from fructose or sucrose. Starch is not hydrolysed
Enzymes catalase positice, oxidase positive, urease positive
Unique features  
ENVIRONMENTAL  
Habitat isolated from fish, processed meat, and poulty products
Lifestyle  
Pathogenicity Strains that grow at 37oC have been isolated from pathological specimens from humans and animals
