THE FERMENTATION OF PURINES BY MICROCOCCUS AEROGENES

Fermentation of amino acids by Micrococcus aerogenes.

The anaerobic micrococci described by Foubert and Douglas (1948a) may be divided into 3 groups on the basis of ability to degrade organic compounds: (1) those capable of fermenting only glycine (Douglas, 1951), (2) those able to degrade purines (Whiteley and Douglas, 1951) and many organic acids (Foubert and Douglas, 1948b), and (3) those able to ferment purines and a limited number of amino ac...

2%Oxypurine Dehydrogenase from Micrococcus aerogenes

Extracts of Micrococcus aerogenes, an anaerobe capable of fermenting purines, contain two enzymes which catalyze the oxidation of 2-oxypurine. These have been purified and separated from one another. One has the broad substrate specificity typical of xanthine dehydrogenase; the other is very specific with regard to the substrates oxidized and will only oxidize 2-oxypurine and closely related co...

Mechanism of the reaction catalyzed by the formate-activating enzyme from Micrococcus aerogenes.

Equations 2 and 3, came from investigations with a highly purified enzyme from Micrococcus aerogenes (6), and from experiments with the pigeon liver enzyme (7-9). On the other hand, data (10, 11) obtained with a formate-activating enzyme from Clostridium cylindrosporum have led to an alternate interpretation, namely that Reaction 1 goes via a concerted mechanism without the formation of any det...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
