PENENTUAN SUHU DAN SUMBER KARBON TERBAIK PADA PERTUMBUHAN ISOLAT SBJ8 DALAM BIODESULFURISASI DIBENZOTIOFENA

The determined of these research were to knowing optimal of temperature and carbon source of biodesulfurization isolate SBJ8. Isolate growth at Medium MSSF-TD with the concentration of 200 ppm DBT in tetradecane which tested various temperature 37?C, 41?C, 45?C. The next step was to determine the best carbon source using glucose, sucrose and citric acid. The result of the experiment showed isolate SBJ8 temperature at 37?C and pH 7 with carbon source of glucose. In condition SBJ8 could growth (OD660) from 0.765, and 0.411 with DBT degradation rate in tetradecane each 76.7%, and 63.4%.
