Thanks to their functional groups, organic acids are used in a wide range of applications: as simple monomers or in the formation of biopolymers, in the presence of at least two functional groups.
As single molecules many "weak" organic acids are used as preservatives (citric acid, sorbic acid, benzoic acid), as additives for detergents (lactic acid) or as antioxidants (ascorbic acid).
Organic Acids are also a key group among the chemical building blocks because they can be used to construct biodegradable polymers, with characteristics that are very similar to their petrochemical counterpart. It is therefore very important to underline that most of these molecules and materials are naturally produced by microbial metabolism or, at the very least, that they are key intermediates.
Biochemical organic acid production from renewable resources is therefore a very important sustainable alternative to petrochemical synthesis products.
