The utilisation of CO(2) in the dissimilation of glycerol by the propionic acid bacteria.
This paper by Wood and Werkman is truly outstanding. First, it is a classical example of determination of the path of a fermentation by careful quantitative analyses of substrates consumed and products formed. Second and most importantly, the results led to the discovery of CO2 fixation by heterotrophic bacteria. The dogma at the time the work was done and as expressed in textbooks held that on...
متن کاملPropionic acid production in glycerol/glucose co-fermentation by Propionibacterium freudenreichii subsp. shermanii.
Propionibacterium freudenreichii subsp. shermanii can ferment glucose and glycerol to propionic acid with acetic and succinic acids as two by-products. Propionic acid production from glucose was relatively fast (0.19 g/Lh) but gave low product yield (~0.39 g/g) and selectivity (P/A: ~2.6; P/S: ~4.8). In contrast, glycerol with a more reduced state gave a high propionic acid yield (~0.65 g/g) an...
متن کاملThe Propionic Acid Fermentation of Lactose.*
Propionic acid was one of the early products observed as resulting from bacterial action. Kearly 70 years ago (1854) Strecker (I) reported it as resulting from a fermentation of mannitol which he had studied, while Pasteur (2) also found propionic acid as one of the products formed in the fermentation of calcium tartrate. As these early observations were not made upon pure cultures, it is impos...
متن کاملa comparative study of the theme of "marriage" in three victorian novelists: charles dickens, george eliot and thomas hardy
این تحقیق کوشیده است با انتخاب پنج رمان از میان آثار برگزیده، «چارلز دیکنز»، «جورج الیوت» و «توماس هاردی » و با رویکردی تطبیقی به بررسی درونمایه ی «ازدواج» در آثار این سه رمان نویس بزرگ دوره ی ویکتوریا بپردازد. فرضیه ی اولیه ی تحقیق این بوده است که چارلز دیکنز (1870- 1812) با زبانی شوخ و گزنده، جورج الیوت(1880- 1819) با نگاهی آموزشی–اندرزگونه و توماس هاردی(1928- 1840) با رویکردی تلخ وانتقادی به...
The Aerobic Dissimilation of Lactic Acid by the Propionic Acid Bacteria.
The hydrogen reacts with lactic acid to form propionic acid. Pyruvic acid has been isolated from the fermentation of glucose (1934) and of lactic acid (unpublished data) by Wood and Werkman. These investigators supported Van Niel's proposed dissimilation of pyruvic acid inasmuch as the occurrence of acetaldehyde could not be demonstrated. Little information is available concerning the aerobic d...
