An industrially applicable Escherichia coli platform for bioconversion of thebaine to oripavine and codeine to morphine

A whole cell Escherichia coli biotransformation platform converting thebaine to oripavine and codeine to morphine was demonstrated with industrially applicable yields (∼1.2 × 10-2 g L-1 h-1 or ∼1.2 × 10-1 g L-1 h-1), improving >13 400-fold upon morphine production in yeast. Mutations enhanced enzyme performance and the use of a purified substrate with rich raw poppy extract expanded applicability.
