The invention relates to cells which make rhamnolipids and are genetically modified such that they have a decreased activity, compared to the wild type thereof, of a glucose dehydrogenase and to a method for producing rhamnolipids using the cells according to the invention.

Rhamnolipid-producing cell having reduced glucose dehydrogenase activity

A method for oxidizing an alkyl, including a) contacting the alkyl with an aqueous solution comprising a microorganism where the microorganism has a reduced fatty acid degradation capacity compared to its wild type, wherein the fatty acid degradation capacity is reduced by deletion, inhibition or inactivation of a gene encoding an enzyme involved in the &#x3b2;-oxidation pathway; and the microorganism expresses a recombinant alkane oxidase, and b) contacting the aqueous solution from a) with a water-immiscible organic solvent.

Biotechnological production of alcohols and derivatives thereof

The invention provides granules comprising

Granules comprising isomaltulose synthase

The invention relates to a process for preparing an &#x3b1;,&#x3c9;-alkanediol comprising the steps of a) reacting an alkanoic acid with an alkanol to give an ester, b) oxidizing at least one terminal carbon atom of the ester by contacting with a whole-cell catalyst, which expresses an alkane hydroxylase, in aqueous solution and in the presence of molecular oxygen, to give an oxidized ester, c) hydrogenating the oxidized ester to form the alkanediol and alkanol, and d) removing the alkanol by distillation, forming a reaction mixture depleted with respect to the alkanol, and recycling the alkanol in step b).

Process for preparing an alpha, omega-alkanediol

The present invention relates to a method of preparing at least one rhamnolipid comprising:
