Die Nutzung der Hefe Yarrowia lipolytica zur Produktion von Citronensäure aus nachwachsenden Rohstoffen
… Pflanzenölen, wie Sonnenblumen- oder Rapsöl, als nachwachsende Rohstoffe. Um zu prüfen, ob die Produktivität der CS-Bildung aus Pflanzenölen mit Y. lipolytica gesteigert werden kann, sollte die Triglyceridverwertung durch die Erhöhung der extrazellulären Lipaseaktivität verbessert werden. Dazu …

Tenside, Polymerbausteine und Polymere aus nachwachsenden Rohstoffen durch Epoxidringöffnungen mit Aminen und enzymatische Polykondensationen
This work describes new syntheses of surfactants and polymers based on renewable raw materials, mainly oleochemical epoxides and polyolamines based on carbohydrates using. Polyolamines, which are available by reductive amination of reducing carbohydrates, were reacted with different epoxides to …

Renewable imidazolium zwitterions as platform molecules for the synthesis of ionic liquids and materials
Following the principles of green chemistry, a simple and efficient synthesis of functionalised imidazolium zwitterionic compounds from renewable resources was developed based on a modified one-pot Debus-Radziszewski reaction. The combination of different carbohydrate-derived 1,2-dicarbonyl …

Biocatalytic conversion of cellulose towards itaconic acid
Naturally occurring cellulose can be used as a renewable resource for the sustainable production of platform chemicals such as itaconic acid. The biocatalytic conversion of cellulose is a very promising approach due to its high selectivity, mild conditions, and low exergy loss. However, such …
