title: [Reasons for the formation of hydrogen sulfide in regenerated water].
abstract: The factors responsible for the formation of hydrogen sulphide in the water reclaimed from the atmospheric condensate were investigated. It was found that hydrogen sulphide developed in reclaimed water due to microorganisms which in the presence of inorganic sulphur (sodium thiosulphate) acquired the capacity to produce hydrogen sulphide, although normally they are not sulphur reducing. Among the microorganisms studied, E. coli showed the highest capacity (100%) and Streptococcus faecalis and Citrobacter freundii showed the lowest capacity (10-20%) to produce hydrogen sulphide.
