Growth Parameters

Hydrogenophaga

PHYSIOLOGICAL

Tropism	chemoorganotrophs, facultative H2 autotrophs
Oxygen	strict aerobe but Hydrogenophaga pseudoflava and Hydrogenophaga taeniospiralis exhibit anaerobic nitrate respiration with denitrification
pH
Temperature
Requirements	grow well on media containing organic acids, amino acids or peptones. Grow less well on media with carbohydrates
Products	A cyclopropane substituted fatty acid (17;cyc) is present. 3-hydroxyoctanoic acid (3-OH-8:0) is present alone or together with 3-hydroxydecanoic acid (3-OH-10:0) 2-hydroxy substitued fatty acids are absent. Ubiquinone Q-8 is present as the main quinone. 2 -Hydroxyputrescine and putrescine are present in roughly equimolar concentrations either exclusively or as the dominant polyamine compounds.
Enzymes	oxidase positive, some species are catalase positive, others are catalase negative
