The Micro-organisms of Fermentation, practically considered

The effect of oxygen on fermentation of sucrose by rumen micro-organisms in vitro.

I. The effect of oxygen on the fermentation of sucrose by mixed rumen micro-organisms in vitro was studied by adding oxygen to the gas phase in three ways: at the beginning of incubation, at two hourly intervals during incubation and continuously. 2. The additions of oxygen had no measurable effect on the utilization of sucrose or on the production of carbon dioxide, steam-volatile acids and pa...

The Biochemistry of Micro - Organisms

I t has been known for some time that Penicillium citrinum Thom when grown on suitable media produces a characteristic lemon yellow colour. Thus Thom in his monograph on “ Cultural Studies of species of 1910), says, “ P. citrinum produces a lemon yellow colour, soluble in alcohol, in media containing sugars, milk, gelatin, bread and potato.” This colouring matter was not isolated, however, nor ...

The Biochemistry of Micro - Organisms

In the following paper an account is given of the investigation of the metabolic products formed from glucose by various species of fungi belonging to different genera. These species were chosen for investigation since the carbon balance sheets prepared for them, when grown on Czapek-Dox glucose solution, indicated that each of them gives rise to considerable quantities of some metabolic produc...

Adaptation in Micro-Organisms

all the humdrum of mental undressing, dressing, shaving, etc., there is the chance reward of being confidential ear to what may never be so well expressed or thought of again. The contributors of the "relatively brief" presentations are six in number. Alex Bavelas talks on "Communication patterns in problem-solving groups"; Ivor A. Richards, on "Communication between men: Meaning and language";...
