The aerobic biodegradation of benzene in laboratory cultures have been well studied, by using
alkaliphilic bacteria strain Bacillus badius D1, The bacterial strain Bacillus badius D1 could complete
degradation of benzene at a concentration of 5 ml/100 ml at pH 9.0 within 48 hrs, The metabolites of aerobic
degradation of benzene by this strain were identified as Catechol, 2-hydroxymuconic semialdehyde and 2-
hydroxypenta-2,4-dienoic acid. The structural determination of the intermediates of benzene degradation was
carried out by spectroscopic analysis like GC-MS chromatography and FTIR spectra. A tentative pathway of
benzene degradation is also reported. To our knowledge, this is the first report that the isolated bacterial
culture of Bacillus badius D1can capable to degraded benzene under alkaline conditions.
