Summary:
Large amounts of a substitute for one of the world's most treasured fragrance ingredients -- a substance that also has potential anti-cancer activity -- could be produced with a sustainable new technology, scientists are reporting. The advance enables cultures of bacteria to produce a substitute for natural ambergris, which sells for hundreds of dollars an ounce.

Large amounts of a substitute for one of the world's most treasured fragrance ingredients -- a substance that also has potential anti-cancer activity -- could be produced with a sustainable new technology, scientists are reporting.

Published in the Journal of the American Chemical Society, the advance enables cultures of bacteria to produce a substitute for natural ambergris, which sells for hundreds of dollars an ounce.

Laurent Daviet, Michel Schalk and colleagues explain that ambergris, a waxy substance excreted by sperm whales, has been prized as a fragrance ingredient for centuries. Ambergris has a pleasant sweet and earthy scent of its own, and it enhances other scents in high-end perfumes. With sperm whales an endangered species, and natural ambergris not used in perfumes in the U.S., perfume makers have turned to substitutes. One is made from sclareol, obtained from the Clary sage plant.

But the plant contains only small amounts of sclareol, and it is laborious to extract and purify. That's why the scientists looked for a better way of making large amounts of sclareol.

Their report describes isolating the genetic material (DNA) that produces the two Clary sage enzymes needed to make sclareol. They put the DNA into bacteria, which made large amounts of sclareol in bioreactors.
