Selective deacetylation of zaluzanin D using transformed Escherichia coli cultures.

The use of conventional and unconventional reaction methodology for the hydrolysis of the acetate group in zaluzanin D resulted in hydration of the 11,13 exocyclic bond along with deacetylation. But the microorganism E. coli selectively cleaved the acetate group to yield zaluzanin C.
