The fate of HFBT in cultures and in the environment is unknown. In this study, HFBT was produced by a DBT-degrading bacterium and purified by sublimation. When stored in organic solvent or as a crystal, the HFBT slowly decomposed, yielding colored products. Two of these were identified as thioindigo and\n cis<\/jats:italic>\n -thioindigo. The supernatant of the DBT-degrading culture contained thioindigo, which has not been reported previously as a product of DBT biodegradation. In mineral salts medium, HFBT was sufficiently stable to allow biodegradation studies with a mixed microbial culture over a 3- to 4-week period. High-performance liquid chromatography analyses showed that HFBT was removed from the medium. 2-Mercaptophenylglyoxalate, detected as benzothiophene-2,3-dione, was found in an HFBT-degrading mixed culture, and the former appears to be a metabolite of HFBT. This mixed culture also mineralized HFBT to CO\n 2<\/jats:sub>\n .\n <\/jats:p>","DOI":"10.1128\/aem.67.2.821-826.2001","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T10:00:58Z","timestamp":1027764058000},"page":"821-826","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":37,"title":["Purification, Stability, and Mineralization of 3-Hydroxy-2- Formylbenzothiophene, a Metabolite of Dibenzothiophene"],"prefix":"10.1128","volume":"67","author":[{"given":"David C.","family":"Bressler","sequence":"first","affiliation":[{"name":"Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada T6G 2E9"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Phillip M.","family":"Fedorak","sequence":"additional","affiliation":[{"name":"Department of Biological Sciences, University of Alberta, Edmonton, Alberta, Canada T6G 2E9"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"235","reference":[{"key":"e_1_3_2_2_2","first-page":"275","article-title":"Some observations on biodegradation of pollutants in aquatic systems.","volume":"30","author":"Bohonos N.","year":"1977","unstructured":"Bohonos N.
