Abstract

Microorganisms degrading carbazole (CA), a model substrate of heterocyclic nitrogen compounds in crude petroleum oil, were screened under microaerobic conditions, i. e. nitrogen gas substituted conditions. Eight bacteria were isolated and identified. For example, Bacillus sp. KUKK-4 degraded 31% of CA when cultivated for 28 days in a medium initially containing CA at 1000mg/l with shaking under the microaerobic conditions.
