  • Method for producing biomass which has a high exopolysaccharide content
    Patent number: 10842174
    Abstract: According to the invention, it was found that culturing of cells of the taxon Labyrinthulomycetes in a high content of sulphate makes it possible to obtain a biomass having a high EPS content, which biomass can in addition be advantageously further processed into a feedstuff.

  • Process for producing a PUFA-containing feedstuff by extruding a PUFA-containing biomass
    Patent number: 10619175
    Abstract: In accordance with the invention, it was found, surprisingly, that a polyunsaturated fatty acids (PUFAs)-comprising biomass with other feedstuff components can be extruded at a low energy input of 12-28 Wh/kg to give an extrudate with a very high oil load capacity.

  • Process for the preparation of hydroxylactones
    Patent number: 6512127
    Abstract: The present invention is directed towards a process for the preparation of enantiomerically enriched 4-hydroxymethyl-&ggr;-butyrolactone (I). By kinetic racemate cleavage of racemic epoxide of the general formula (II) wherein R represents a (C1-C8)-alkyl radical, a (C8-C16)-aryl radical, with a nucleophile and a Jacobsen catalyst there is obtained enantiomerically enriched (I). Use of the lactone so prepared.
