Evidence for two different types of insecticidal P2 toxins with dual specificity in Bacillus thuringiensis subspecies.

abstract：:Based on its genome sequence, the pathway of beta-oxidative fatty acid degradation in Salmonella enterica serovar Typhimurium LT2 has been thought to be identical to the well-characterized Escherichia coli K-12 system. We report that wild-type strains of S. enterica grow on decanoic acid, whereas wild-type E. coli str...
