ABSTRACT

This paper reports the isolation and characterization of a new o-nitrobenzaldehyde (ONBA)-degrading bacterium, Alcaligenes sp. ND1. ND1 degraded almost all ONBA (100 mg L-1) in M9 medium within 36 hours. The key enzyme(s) involved in the initial biodegradation was a constitutively intracellular enzyme(s). This bacterium has great potential utility for bioremediation.


Esse trabalho relata o isolamento e a caracterização de uma nova bactéria degradadora de o-nitrobenzaldeido (ONBA), Alcaligenes sp ND1. A bactéria ND1 decompôs todo o ONBA (100 mg.L-1) do meio M9 em 36 horas. A enzima-chave envolvida na biodegradação inicial foi uma enzima constitutiva intracelular. Esta bactéria apresenta um potencial de aplicação para bioremediação.
