Growth Parameters

Enterobacter

PHYSIOLOGICAL

Tropism
Oxygen	Facultatively anaerobic
pH
Temperature	Optimum temperature for growth, 30`C. Most clinical strains grow at 37`C; some environmental strains give erratic biochemical reactions at 37`C
Requirements
Products	Ferment glucose with production of acid and gas (generally CO2:H2 = 2:1). Gas is not produced from glucose at 44.5`C. Most strains give a positive Voges-Proskauer reaction and a negative methyl red test. Citrate and malonate are usually utilized as sole sources of carbon and energy. Hydrogen sulfide is not produced from thiosulfate. Gelatin is liquefied slowly by most strains.
Enzymes	Deoxyribonu-clease (DNase), Tween 80 esterase and lipase are not produced
