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 -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 -L-rhamnosidase enzyme does not have -D-glucosidase activity.

Described is a method of producing bioproducts by fermentation with a genetically modified cell, as well as to the genetically modified cell used in the method. The cell is genetically modified to produce a bioproduct and is further genetically modified by reducing the expression of at least one endogenous membrane protein encoding gene and/or mutating the expression of the endogenous membrane protein.

The subject invention provides microbe-based products, as well as their use to improve oil production and refining efficiency by, for example, remediating the disposable layers in oil tanks and other oil storage units. In preferred embodiments, the microbe-based products comprise biochemical-producing yeast and growth by-products thereof, such as, e.g., biosurfactants. The subject invention can be used to remediate rag layer and/or other dissolved solid layers that form in water-oil emulsions. Furthermore, the subject invention can be used for remediating solid impurities, such as sand, scale, rust and clay, in produced water, flow-back, brine, and/or fracking fluids.
