A microbial consortium, ATCC 202177, is enriched to remove target sulfur compounds from gases in the presence of ammonia, cyanide, carbon monoxide, and other toxic gases and mixtures thereof. The ATCC 202177 consortium is cultured in an anaerobic or aerobic nutrient medium until enough cells of ATCC 202177 are recovered to remove the target sulfur species at a pressure ranging from 1 to 80 atmospheres.

[ What is claimed is:] [1.]1. A method for preparing an enriched culture of microbial consortium ATCC 202177 by:a) contacting said consortium ATCC 202177 with an organic nitrogen source; one or more gaseous sulfur compounds; at least one compound selected from the group consisting of ammonia, carbon dioxide, carbon monoxide, hydrogen cyanide, methane, higher gaseous hydrocarbons, and mixtures thereof; and a mineral salt solution as a nutrient medium for the microorganisms;b) maintaining the microbial consortium of step a) in the nutrient medium for a time sufficient to obtain an enriched consortium ATCC 202177 which reproducibly metabolizes sulfur compounds in a gas stream containing at least one of ammonia, carbon dioxide, carbon monoxide, hydrogen cyanide, methane, higher gaseous hydrocarbons, nitrogen and mixtures thereof;c) recovering said enriched consortium ATCC 202177 consortium of step b).
