Abstract
The invention concerns a process to convert di-rhamnolipid to mono-rhamnolipid comprising the following process steps: —(a) contact of a starting di-rhamnolipid material with an α-L-rhamnosidase enzyme which is immobilised on a support; (b) separation of the produced mono-rhamnolipid from the reaction medium and/or side products; wherein the α-L-rhamnosidase enzyme does not have β-D-glucosidase activity.

A process to convert di-rhamnolipid to mono-rhamnolipid comprising the following process steps:
- (a) contacting a starting di-rhamnolipid material with an α-L-rhamnosidase enzyme which is immobilised on a support;
- (b) separating a produced mono-rhamnolipid from a reaction medium and/or side products;
- wherein the α-L-rhamnosidase enzyme does not have β-D-glucosidase activity and is from Aspergillus lentulus, and the resulting mono-rhamnolipid material has a carbon alkyl length of from C8 to C14.
