Bioseparation of 1,3-propanediol
Bioseparation of 1,3-propanediol is a biochemical process for production of 1,3-propanediol (PDO). PDO is an organic compound with many commercial applications. Conventionally, PDO is produced from crude oil products such as propylene or ethylene oxide. In recent years, however, companies such as DuPont are investing in the biological production of PDO using renewable feedstocks such as corn.〔http://www.chem.uu.nl/brew/BREWsymposiumWiesbaden11mei2005/WEBSITEBrewPresentations51105.PDF〕〔http://www.azom.com/News.asp?NewsID=8862〕
==History==
In May 2004, DuPont and Tate & Lyle announced that they would start up a joint venture to build a facility that produces polymers from renewable feedstock instead of petrochemicals.〔 In particular, their goal was to design a fermentation system that converts corn sugar into PDO (propanediol manufactured in this way is referred to in the media as "BioPDO"). They argue that using such a bioprocess is more energy efficient than conventional petrochemical processes (conversion of propylene into propanediol) because the bioprocess has four advantages over the conventional process: smaller environmental footprint, lower operating costs, smaller capital investment, and greater sustainability due to use of renewable corn feedstock.〔
