The invention relates to sophoroselipids of formula (I) wherein R4 represents H, -CH¿2?CH3, -CH2CH2CH3, n is an integer number from 2 to 27, R?1 and R2¿ represent, independently from each other, H or a group of formula (II), and R3 represents H or -OH. The invention also relates to a method for producing sophoroselipids of formula (I) wherein R?1, R2, R3¿ and n have the aforementioned meanings and R4 represents -CH¿3?, -CH2CH3 or -CH2CH2CH3. According to this method, a yeast capable of secreting a sophoroselipid in the form of a lactone in the culture excess, is fermented in a culture medium containing a glycerin, a succinate, a mono-, di- and/or tri-saccharide and a lipid precursor, said sophoroselipid being then isolated from the culture solution. The inventive method is characterised in that the lipid precursor contains one or more 3-alkanols, 4-alkanols or an alkanone with a chain length from 6 to 30 carbon atoms or mixtures of said alkanols/alkanone. Furthermore, according to a variant of the aforementioned method for producing sophoroselipids of formula (I), wherein R?1, R2, R3¿ and n have the meanings aforementioned and R4 represents -CH¿3?, -CH2CH3 or -CH2CH2CH3, the culture medium is maintained during fermentation under a reduced oxygen concentration. The new sophoroselipids may be used, e.g., as surfactants, cosmetics, disinfecting agents or pharmaceutical products.

摘要:
The invention relates to a starch-based thermoplastic mixture, obtained by preparing and mixing A) 100 weight parts of at least one cationic starch a) and at least one anionic starch b), B) 0-400 weight parts of a polymer material which can be thermoplastically processed and is different from A), C) water in a sufficient quantity for plasticising the mixture, D) at least one plasticiser in a quantity of 10 weight parts - half the sum of the weight parts of A) and B), and E) optionally, up to ((A) + B)) weight parts of other usual additives, the water content of constituents A) and B) having been corrected to zero by calculation. The invention also relates to the use of the inventive mixture for producing shaped bodies and films.

Die Erfindung betrifft ein Verfahren zur Kultivierung von Ciliaten in sogenannten Spinnerflaschen. Diese ursprünglich für die Kultivierung von tierischen Zellen entwickelte Methode läßt sich erfolgreich auch bei Ciliaten anwenden.
摘要:
The invention relates to a method for producing aqueous, hydrous and non-aqueous solutions of polymers that are functionalized by acid groups. The method is characterized in that the heat needed to produce the solution is supplied by microwave radiation. These solutions can be used as a starting material for the production of gas diffusion electrodes, fuel cells and platinum nanoparticles stabilized by polymer-electrolytes.
