  • Method for the Identification of Sulfo-Oxidizing Bacteria and for the Monitoring of Elemental Sulfur in the Environment
    Publication number: 20080311577
    Abstract: A method is described for the identification of sulfooxidizing bacteria comprising the extraction of the DNA from environmental samples and the subsequent identification of at least one fragment of the Thio 16S gene or SoxB gene present in these bacteria. The method can be used for determining the level of elemental sulfur in samples of soil.
