Abstract
Combinations of a nitroprusside, such as sodium nitroprusside (SNP; Na[Fe(CN)NO].2HO) and a nitrate, are provided, together with methods for the combined use of the nitroprusside and the nitrate as metabolic inhibitors of microbial cultures. The microbial cultures may include sulfate reducing bacteria (SRB) in aqueous culture. This metabolic inhibition may for example be implemented in the presence of a hydrocarbon, for example in an oil reservoir or in oil field systems and facilities. When applied to an SRB culture in the presence of a hydrocarbon, the combination of the nitroprusside and the nitrate may accordingly be used to ameliorate the biological formation of sulfides, particularly hydrogen sulfide.
