Inhibition of the main respiratory chain by 1 mm-NaN3 prevents H2S consumption. At higher concentrations, H2S inhibits respiration incompletely; the inhibition is enhanced by 1 mm-salicylhydroxamic acid. Thus this organism has two means of protection against the potentially toxic gas: the ability to oxidize H2S, and the presence of alternative pathways of electron transport which are not blocked by this respiratory inhibitor. %U https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-126-1-167
