Description
Czesc roztworu glównego, niezuzytego do powyzszego doswiadczenia, pozostawia sie przez 24 godzin w temperaturze okolo —10°C, a po oditajaniu uzywa db sfermen¬ towania cukru (w wyzej podanym stosun¬ ku). W poczatkowem stadjum reakcji moz¬ na bylo stwierdzic 5,6 i wiecej cm3 kwasu weglowego, wytworzonego w ciagu 1 se¬ kundy, który to fakt zgadza sie ze zmniej¬ szeniem sie lepkosci z 80.80 sek (25° na 78,36 sek) 25°, wzglednie z wzrostem na¬ piecia powierzchniowego z 41.45 dyn (25° na 45,89 dyn) 25°.Przyklad II. Przez 20 cm3 10% zawie¬ siny górnofermentacyjnych drozdzy piw¬ nych w nasyconej bezwodnikiem weglo¬ wym wodzie wodociagowej przepuszcza sie w ciagu 5 minut umiarkowany strumien (60—70 pecherzyków przeplywa na minu¬ te) etylenu handlowego, poczem bezpo¬ srednio przeprowadza sie fermentacje przy kilkakrotnem dodawaniu po 1 g glukozy (porówn. fig. 2). — 2 —Przyklad III. Przez 20 cm3 zawiesiny górnofermentacyjnych drozdzy przepu¬ szcza sie, jaJk wyzej, etylen i do zawiesiny tej, pozostawionej przez cala noc w za- mknietem naczyniu i w chlodnem miejscu, dodaje sie 0,2 g swiezo destylowanego kwasu pyrogronowego. (Na fig. 3 przedsta¬ wia dolna para krzywych fermentacje kwa¬ su z ,,ochraniaczem" i bez niego). Reakcja zachodzi w ciagu mniej wiecej 24 godzin.Nastepnie drozdze przemywa sie kilka¬ krotnie woda, dokladnie odwirowuje i je¬ szcze raz wytwarza z nich zawiesine w wo¬ dzie wodociagowej, nasyconej kwasem we¬ glowym. Po dodaniu kazdorazowo 1 g glu¬ kozy, przeprowadza sie fermentacje, któ¬ rej przebieg przedstawia górna para krzywych (fig. 3).Przyklad IV. Przez zawiesine 5 g kra¬ janki swiezo zebranego tytoniu w 60 cm3 wody przepuszcza sie strumien etylenu, poczem rozciencza te zawiesine 15 cm3 30% wody utlenionej w ten sposób, aby poczatkowa koncentracja wody utlenionej wynosila okolo 6%, Przebieg wydzielania sie tlenu przez katalaze przedstawiaja pa¬ ry krzywych ma fig. 4. PLPart of the main solution, not used for the above experiment, is left for 24 hours at a temperature of about -10 ° C, and after deflation, sugar fermentation is used (in the above-mentioned ratio). At the initial stage of the reaction, 5.6 and more cc of carbonic acid could be found, produced in 1 second, which corresponds to a viscosity reduction of 80.80 seconds (25 ° to 78.36 seconds) 25 °, relative to an increase in surface tension from 41.45 dynes (25 ° to 45.89 dynes) 25 °. Example II. A moderate stream (60-70 bubbles per minute) of commercial ethylene is passed through 20 cm.sup.3 of a 10% suspension of beer yeast in carbonic anhydride-saturated tap water, and the fermentation is then carried out directly on the repeated addition of 1 g of glucose each (compare Fig. 2). - 2 - Example III. Ethylene, as above, is passed through 20 cm3 of the upper fermentation yeast suspension, and 0.2 g of freshly distilled pyrogronic acid is added to the suspension, left overnight in a closed vessel and in a cool place. (Figure 3 shows the lower pair of curves fermentations of the acid with and without protector.) The reaction takes about 24 hours. The yeast is then washed several times with water, thoroughly centrifuged, and once more. They are made into a suspension in tap water, saturated with carbonic acid. After the addition of 1 g of glucose each time, fermentation is carried out, the course of which is shown in the upper pair of curves (Fig. 3). Example IV. The fringes of freshly harvested tobacco are passed through a stream of ethylene in 60 cm3 of water, and then the suspension is diluted with 15 cm3 of 30% hydrogen peroxide in such a way that the initial concentration of hydrogen peroxide is about 6%. see Fig. 4.
