Unconventional approaches for the induction of microbial natural products.

Expansion of the microbial drug discovery pipeline has been impeded by a limited and skewed appreciation of the microbial world and its full chemical capabilities and by an inability to induce silent biosynthetic gene clusters (BGCs). Typically, these silent genes are not expressed under standard laboratory conditions, instead requiring particular interventions to activate them. Genetic, physical, and chemical strategies have been employed to trigger these BGCs, and some have resulted in the induction of novel secondary metabolites.
