Interspecies hydrogen transfer

Interspecies hydrogen transfer (IHT) is a form of interspecies electron transfer.[1] It is a syntrophic process by which H2 is transferred from one organism to another, particularly in the rumen and other anaerobic environments.[1]

IHT was discovered between Methanobacillus omelianskii and an "S" organism in 1967 by Marvin Bryant, Eileen Wolin, Meyer Wolin, and Ralph Wolfe at the University of Illinois.[2] It was shown in 1973 that this process occurs between Ruminococcus albus and Wolinella succinogenes.[3]

This process affects the carbon cycle: methanogens can participate in interspecies hydrogen transfer combining H2 and CO2 to produce CH4.[4] Besides methanogens, acetogens, and sulfate-reducing bacteria can participate in IHT.[5]
