Isolation and preliminary characterization of a o-nitrobenzaldehyde-degrading Alcaligenes sp. ND1 [PDF]

Brazilian Journal of Microbiology, 2008
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).

Elucidation of antibacterial activity of Bacillus sp. and Alcaligenes sp. metabolites against multidrug-resistant bacteria

Nova Biotechnologica et Chimica, 2022
Different resistance mechanisms are involved in exhibiting resistance to different groups of antibiotics. Researchers are searching for new therapeutic options to encounter the emerging trend of microbial resistance. Bacteria were isolated from the extreme environment of Cholistan Desert and were screened for characterization.
