Studies on the Mechanism of Acetate Oxidation by Bacteria
The data presented in this paper indicate operation of different mechanisms for acetate oxidation by A. aerogenes, depending on the carbon source used for growth. The mechanism for citrate-grown cells appears to involve a conventional citric acid cycle, whereas acetate-grown cells appear to incorporate acetate carbon more readily via a dicarboxylic acid cycle.
متن کاملXxiii. Oxidation-reduction Potentials of Pneumococcus
IN previous communications the electrode potential behaviour of haemolytic streptococci [Hewitt, 1930, 1], C. diphtheriae [1930, 2], staphylococci [1930, 3] and pneumococci [1930, 4] has been described by the author and it has been shown that the oxidation-reduction potentials established in bacterial cultures depend upon the cultural conditions and upon the organism studied. The potentials dev...
متن کاملThe First Ring-Expansion of a 1-Azabicyclo[1.1.0]butane to a 1- Azabicyclo[2.1.1]hexane
The reactions of 3-phenyl-1-azabicyclo[1.1.0]butane (4) with dimethyl dicyanofumarate ((E)-8) and dimethyl dicyanomaleate ((Z)-8) lead to the same mixture of cisand trans-4-phenyl-1-azabicyclo[2.1.1]hexane 2,3-dicarboxylates (cis-11 and trans-11, resp.; Scheme 3). This result of a formal cycloaddition to the central C-N bond of 4 is interpreted by a stepwise reaction mechanism via a relatively ...
متن کاملPhysiological studies of methane and methanol-oxidizing bacteria: oxidation of C-1 compounds by Methylococcus capsulatus.
Methylococcus capsulatus grows only on methane or methanol as its sole source of carbon and energy. Some amino acids serve as nitrogen sources and are converted to keto acids which accumulate in the culture medium. Cell suspensions oxidize methane, methanol, formaldehyde, and formate to carbon dioxide. Other primary alcohols are oxidized only to the corresponding aldehydes. Oxidation of formate...
متن کامل1-Butyl-3-Methylimidazolium Bromide Promoted Selectively Oxidation of Sulfur Compounds by NaBrO3
1-Butyl-3-methylimidazolium bromide ([bmim]Br) as an ionic liquid promoted selectively oxidation of aliphatic and aromatic sulfides to the corresponding sulfoxides and the oxidative coupling of thiols to disulfides by NaBrO3 in excellent yields under neutral conditions.
