Verfahren zur Herstellung von Nährstoffen fiir die Hefe zum Zweck der Presshefe- fabrikation.
Das vorliegende Verfahren zielt darauf ab, animalische Abfallprodukte, wie beispielsweise Abfälle von Fischkonserven, Rückstände der zur Ölgewinnung dien : nden ungeniessbaren Fische, Fisehguano, Fleisch-, Blut-, Horn-, Ledermehl u. dgl. für die Ernährung der Hefe zum Zweck der Presshefefabrikation dienstbar zu machen. Zu diesem Behufe werden die Abfälle unter Zusatz von Alkalien oder Erdalkalien, insbesondere Kalk, einer Destillation mit Wasserdampf unterworfen, wodurch die Geruchstoffe abgetrieben werden und ein grosser Teil der stickstoffhaltigen Verbindungen in Lösung geht, wogegen die übrigen Bestandteile ungelöst bleiben. Die Lösung kann nun unmittelbar als Nährmittel für die Hefe verwendet oder vorher konzentriert werden. Die Rückstände können auf Düngemittel verarbeitet werden.
Es ist bereits vorgeschlagen worden, das Keratin in tierischen Haaren und ähnlichen keratinhaltigen Produkten durch Behandlung mit Säuren, Alkalien oder durch sehr lange anhaltendes Erhitzen mit Wasser unter Druck zu hydrolysieren und entweder die so erhältliche Lösung selbst oder ihren Trocken-

Behandlung gemäss der vorliegenden Erfindung hat gleichzeitig den Vorteil, dass die Geruchstoffe entfernt werden, was für den angestrebten Zweck von wesentlicher Bedeutung ist.

Process for the production of nutrients for yeast for the purpose of compressed yeast manufacture.
The aim of the present process is to remove animal waste products, such as canned fish waste, residues from oil production: inedible fish, fish guano, meat, blood, horn, leather meal and the like. Like. For the nutrition of the yeast for the purpose of the pressed yeast production serving. For this purpose, the waste is subjected to a distillation with steam with the addition of alkalis or alkaline earths, especially lime, whereby the odorous substances are driven off and a large part of the nitrogenous compounds go into solution, while the other components remain undissolved. The solution can now be used directly as a nutrient for the yeast or concentrated beforehand. The residues can be processed onto fertilizers.
It has already been proposed to hydrolyze the keratin in animal hair and similar keratin-containing products by treatment with acids, alkalis or by heating for a long time with water under pressure and either the solution obtained in this way or its drying
EMI1.1
Treatment according to the present invention also has the advantage that the odorous substances are removed, which is of essential importance for the intended purpose.
