An assay for aprA-based functional gene analysis was developed for determination of the SRP and SOP diversity in environmental samples. In addition, the distribution of the sulfate thiol hydrolase (SoxB, a component of the thiosulfate-oxidizing multi-enzyme system Sox) in SOP was investigated.deinfo:eu-repo/semantics/openAccessAPS reductaseAprBAphylogenysulfate-reducing prokaryotessulfur-oxidizing prokaryotesevolutionhomology modelingSoxBSox enzyme systemmicrobial diversity analysismolecular markerdeep-sea spongesymbionts570Dissertationurn:nbn:de:gbv:46-diss000113420
