Growth Parameters Klebsiella
PHYSIOLOGICAL  
Tropism  
Oxygen Facultatively anaerobic, having both a respiratory and a fermentative type of metabolism.
pH  
Temperature  
Requirements There are no special growth factor requirements
Products Most strains can use citrate and glucose as a sole carbon source. Glucose is fermented with the production of acid and gas (more CO2 is produced than H2), but anaerogenic strains occur. Most strains produce 2,3-butanediol as a major end product of glucse fermentation and the Voges-Proskauer test is usually psotivive; lactic, acetic and formic acids are formed in smaller amounts and ethanol in larger amounts than in a mixed acid fermentation. Fermentation of inositol, hydrolysis of urea, and lack of production of ornithine decarboxylase or H2S are further distinctive characters. Some strains fix nitriogen
Enzymes Oxidase-negative
