About the Book

Sulfoniertes lineares Alkylbenzol (LAS) ist ein anionisches Tensid, das in der Formulierung von Wasch- und Reinigungsmitteln verwendet wird. Dieses Tensid ist für deren Formulierung unverzichtbar, aber es ist nicht vollständig biologisch abbaubar und kann für die aquatische Umwelt toxisch sein. Um die Effizienz des Fadenpilzes Penicillium chrysogenum beim biologischen Abbau von LAS zu analysieren, wurde ein Versuchsplan mit drei axialen Punkten erstellt, um die Konzentrationen von Glucose und LAS in insgesamt elf Versuchen zu variieren. Die Versuche wurden fünf Tage lang in einem Schüttler bei 25 °C und 180 U/min bebrütet, um die Fermentation zu ermöglichen. Um diese Reduktion zu quantifizieren, wurde eine Analyse auf der Grundlage der Methylenblau-Methode (MBAS) durchgeführt. Der in dem Verfahren verwendete Fadenpilz Penicillium chrysogenum erwies sich als fähig, anionische Tenside biologisch abzubauen, die häufig in Flüssigwaschmitteln verwendet werden, die täglich in die häuslichen Abwässer eingeleitet werden, und die, obwohl sie biologisch abbaubar sind, einen hohen Grad des biologischen Abbaus von LAS erreichten, der 99,4 % betrug, während herkömmliche Behandlungen in Anaerobiose höchstens 70 % der Tenside in realen Abwässern entfernen.
