A research team led by Switzerland’s science and technology university ETH Zurich has demonstrated a new process that manufactures succinic acid from wood instead of oil.
Succinic acid is a major basic chemical product that is added to fuel and lubricants to protect motors from corrosion.
The new process uses bacteria to manufacture succinic acid in a method demonstrated to be cost-effective, environmentally friendly and safe.
Succinic acid is added to fuel and lubricants to protect motors from corrosion. It goes under the name of E 363 in the food industry, where it is used as an acidifier and flavour enhancer, and to introduce air into food products. However, succinic acid is used predominantly as a starting point to create a huge range of chemical compounds: among other things, it is used to manufacture vitamins, medication, solvents, crop protection products, polymers and aromatic substances for perfumes.
