The Oxidation of Glycerol by Streptococcus faecalis

The vitamin requirements for glycerol oxidation by Streptococcus faecalis.

Gunsalus and Sherman (1943) have shown that oxygen is necessary for glycerol fermentation for the majority of the lactic acid bacteria. These organisms, though considered devoid of those iron enzymes usually necessary when oxygen is involved as a hydrogen acceptor, could aerobically utilize glycerol. Because of the anomaly of these observations Gunsalus and Umbreit (1945) studied the mechanism ...

Diacetyl oxidation by Streptococcus faecalis, a lipoic acid dependent reaction.

In the over-all reaction, one molecule of diacetyl is oxidized to two molecules of acetate, and another molecule of diacetyl is reduced to acetoin. The reaction was shown to require cocarboxylase (DPT).2 Subsequently, Schweet et al. (1951) expanded this finding and pointed out the similarity between the diacetyl reaction and pyruvic acid oxidation, with respect to the metabolism of the "active ...

The oxidation of glycerol by Mycobacteria.

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...

Phospholipids of Streptococcus faecalis.

Autoradiograms of total lipid extracts from Streptococcus faecalis ATCC 9790, harvested in the stationary phase from a medium containing (32)P-orthophosphate, showed six major spots. The corresponding compounds were identified as diphosphatidylglycerol (possibly with a penta acyl structure); phosphatidylglycerol; a provisionally identified mixture of alanylphosphatidylglycerol and of the 2'-lys...
