Characterization of partial anaerobic metabolic pathway for 2,4,6-trinitrotoluene degradation by a sulfate-reducing bacterial consortium.

abstract：:Salmonella typhimurium and a series of rough lipopolysaccharide mutants derived from it were used as target bacteria to examine the antimicrobial capacity of magainin 2. Magainin 2 demonstrated a dose-related bactericidal activity against the smooth parent strain and the series of lipopolysaccharide mutants. The lipop...
