Monascus ruber as a cell factory for the production of lactic acid at low pH

Lactic acid has already been produced for decades for the food and feed market. Lactic acid can also be used for the production of the biobased polyester polylactic acid, but this application has a lower added value. The existing manufacturing processes are too expensive. To effectively compete with fossil based polymers it is therefore necessary to reduce costs significantly.

We have identified which traits a microorganism ideally should have to produce lactic acid efficiently at low costs. Based on this, we have isolated the most suitable microorganism from nature, and converted it into an effective lactic acid producing cell factory by genetic and evolutionary engineering.
