| Comment: | L. mesenteroides is an important bacterium in the process that leads to fermented vegetables.
The Uppsala company Pharmacia had great success in the 40s and 50s with, among other things, a plasma replacement product (Macrodex), which is based on dextran produced by L. mesenteroides. Pharmacia was bought by various companies and Macrodex is not produced in Uppsala any longer, but it is used worldwide in both human and veterinary medicine. | ||||||||
