METHOD OF USING AN IRON ADDITIVE AS A MEDIA SUPPLEMENT FOR DETECTION OF SULFATE REDUCING BACTERIA

摘要

According to the present invention a method of determining a concentration of sulfate reducing bacteria (SRB) comprising is provided. The method comprises preparing a standard growth medium in a group of test vials, adding ferrous chloride tetrahydrate (FCTH) to the each of the test vials, adding a sample portion to a first of the group of test vials, sequentially diluting the sample portion by injecting succeeding vials in the test group with fluid from sequentially previous vials and incubating the group of test vials, wherein blackening of fluid in an incubated test vial indicates a presence of a threshold number of SRB.
