In 1952 two Upjohn biochemists, Dury Peterson and Herb Murray announced that they were able to introduce this crucial oxygen atom by fermentation of the steroid progesterone with the mold Aspergillus nigercans. Over the next several years a group of chemists headed by John Hogg developed a process for preparing cortisone from the soybean steroid stigmasterol. The microbiological oxygenation is a key step in this process. Monsanto was part of the acquisition and divesting scheme at Pfiser and ties to the soy interest.
