Flame retardants and pesticides responsible for intellectual disabilities among millions
To isolate endophytes, the researchers spread fresh, cut-up pieces of S. sessilifolia on agar plates. They then collected the bacteria that grew on the plates, analyzed the DNA and identified the microbes as Streptomyces clavuligerus . Using nuclear magnetic resonance spectroscopy and mass spectrometry, the team purified 10 new compounds from the bacteria with structures similar to a class of insecticides known as pyrroles. Testing the substances on insects revealed that they were strongly toxic to aphids and moderately toxic to spider mites. A bacterial extract containing all of the compounds had greater lethal activity than any compound alone. These substances, or the bacteria that produce them, could be promising new natural pesticides, the researchers say.
