From: Reductive metabolism of the important atmospheric gas isoprene by homoacetogens
Depletion of isoprene (a) in 80 ml anaerobic cultures containing an enriched isoprene reducing culture supplied with H2 + HCO3− + isoprene and reciprocal production of 2-methyl-1-butene (b) and 3-methyl-1-butene (c). In control samples supplemented with only H2 + isoprene or only HCO3− + isoprene no methylbutene formation or isoprene depletion was detected. Error bars represent one standard deviation (n = 4)
