Description

Verfahren zur Beschleunigung der Hefegärung Es ist bekannt, daß man den Stoffwechsel vcn Mikroorganismen durch Vitamin BI oder Pantothensäure beschleunigen kann. Diese Wirkung gilt als so spezifisch für Vitamin Bi, daß man vorgeschlagen hat, hierauf eine Bestirylrnungsmethode für Vitamin Bi zu gründen. Ferner war bekannt, daß Aminosäuren keinen Einfluß auf die Gärungsgeschwindigkeit lebender Hefen haben.Process for accelerating yeast fermentation It is known that the metabolism of microorganisms can be accelerated by vitamin BI or pantothenic acid. This effect is said to be so specific for vitamin Bi that it has been proposed to base a determination method for vitamin Bi on it. It was also known that amino acids have no influence on the fermentation rate of living yeasts.

Weiter weiß man, daß z. B. Vitamin Bi und seine Spaltstücke fördernd auf das Wachstum von Mikroorganismen, wie Hefen, wirken. Glykokoll hat sich in dieser Beziehung als inaktiv erwiesen.It is also known that z. B. Vitamin Bi and its splits promoting act on the growth of microorganisms such as yeast. Glycocolla has been found in this Relationship proven inactive.

Es war daher höchst überraschend, als gefunden wurde, daß die einfachste Aminosäure, Glykokoll, den Stoffwechsel von Mikroorganismen erheblich beschleunigt. Eine besonders große Stimulierung der Stoffwechselgeschwindigkeit ergibt sich, wenn man Vitamin B1 und /oder Pantothensäure mitverwendet. An Stelle von Vitamin Bi können auch Spaltstücke des Vitamin B1 und Derivate davon, wie 2-Methyl-G-ainiriopyrirnidine, die in 5-Stellung durch Methyl-, Oxymethyl-, Alkoxymethyl-, Acy loxjrinethyl-, Aminomethyl-, Halogenmethylreste substituiert sind, angewandt werden.It was therefore most surprising when it was found that the simplest Amino acid, glycocolla, significantly accelerates the metabolism of microorganisms. A particularly large stimulation of the metabolic rate results when vitamin B1 and / or pantothenic acid are also used. Instead of vitamin Bi you can also split pieces of vitamin B1 and derivatives thereof, such as 2-methyl-G-ainiriopyrirnidine, those in the 5-position by methyl, oxymethyl, alkoxymethyl, acyloxyrinethyl, aminomethyl, Halomethyl radicals are substituted, can be used.

Der in Gegenwart von Glykolcoll erhöhte Umsatz des gegebenenfalls Vitamin Bi- und/ oder pantothensäurehaltigen Nährmediums beruht nicht auf einer Wachstuiinsbeschleunigung, bedingt durch das Vorhandensein einer leicht assimilierbaren Stickstoffquelle, da die notwendigen Mengen dieser Stoffe viel zu klein sind, als daß sie als Nährstoff ins Gewicht fallen könnten. Außerdem tritt die Stoffwechselaktivierung bereits zu einer Zeit ein, in der die Vermehrung der Mikroorganismen praktisch noch nicht begonnen hat.The conversion of the possibly increased in the presence of Glykolcoll Vitamin bi- and / or pantothenic acid-containing nutrient medium is not based on one Acceleration of growth due to the presence of an easily assimilable Source of nitrogen, as the necessary quantities of these substances are much too small than that they could matter as a nutrient. In addition, the metabolic activation occurs already at a time when the multiplication of microorganisms was practically still going on has not started.

Män hat bereits Extrakte aus Naturstoffen, wie Hefe, Leber oder Malz, zur Steigerung der Hefegärung angewendet. Diese Extrakte kommen aber ihres hohen Preises wegen für die Technik nicht in Betracht. Die Erkenntnis von der Bedeutung des technisch leicrt. zugänglichen Glykokolls hierfür bedeutet demgegenüber einen bedeutenden Fortsch, i tt.Man already has extracts from natural substances such as yeast, liver or malt, used to increase yeast fermentation. These extracts come at a premium Due to the price for the technology not considered. The realization of the meaning of the technical easily. accessible glycocolls for this means in contrast significant progress.

Die maximale Gärungsgeschwindigkeit betrug 64 ccm Kohlendioxyd pro Stunde bei 30° C, während ein Parallelversuch mit zusätzlich 2o mg Glykokoll maxianal 89 ccm Kohlendioxyd pro Stunde entwickelte.Example iig baker's yeast was used in zoo ccm of a nutrient solution containing 10 g glucose> 0.3 g ammonium sulfate, 0.07 g magnesium sulfate, 0.06 primary and 0.016 g secondary potassium phosphate, 0.05 g sodium chloride, 0.94 g calcium nitrate and 0.3 mg vitamin Bi suspended. The maximum fermentation rate was 64 ccm of carbon dioxide per hour at 30 ° C, while a parallel experiment with an additional 20 mg of glycocolla developed a maximum of 89 ccm of carbon dioxide per hour.

Setzte man sowohl 2o mg Glykokoll als .auch 5o mg Pantotliensäure hinzu, so erhielt man die maximale Gärungsgeschwindigkeit von 98 ccm Kohlendioxyd pro Stunde.If both 20 mg glycocolla and 50 mg pantotlenic acid were used in addition, the maximum fermentation rate of 98 cc of carbon dioxide was obtained per hour.
