Recycling of alkali sulfate rich waste water by biological pre-treatment with an extreme halophilic organism

Abstract

The present invention relates to an aqueous composition comprising cells of at least one strain of a halophilic microorganism, and alkali sulfate in a concentration of at least 30 g/l based on the total volume of the aqueous composition. The present invention further relates to a method for treating a waste water, comprising obtaining or providing a waste water, contacting said waste water with cells of at least one strain of a halophilic microorganism, and thereby generating an aqueous composition comprising alkali sulfate in a concentration of at least 30 g/l, and incubating said aqueous composition under conditions which allow for the treatment of the waste water.
