The utilization of nitrogen in various compounds by Clostridium pasteurianum.
In biological nitrogen fixation the key intermediate compound, defined as the end product of the fixation reaction and the initial reactant of assimilation, is believed to be either ammonia or hydroxylamine. Burris and Wilson (1945) noted that these two possibilities need not be mutually exclusive but may occur simultaneously, depending on the concentrations of the carbon compounds serving as a...
متن کاملBiosynthesis of amino acids in Clostridium pasteurianum.
1. Clostridium pasteurianum was grown on a synthetic medium with the following carbon sources: (a) (14)C-labelled glucose, alone or with unlabelled aspartate or glutamate, or (b) unlabelled glucose plus (14)C-labelled aspartate, glutamate, threonine, serine or glycine. The incorporation of (14)C into the amino acids of the cell protein was examined. 2. In both series of experiments carbon from ...
متن کاملThe Hydrogenase System of Clostridium pasteurianum
Peck and Gest (1) reported that crude extracts of Clostridium butylicum produce small amounts of hydrogen from aqueous dithionite (hydrosulfite). Hydrogen evolution from dithionite decreased upon dilution of the crude extracts and was lost upon further purification (2). This loss of activity was interpreted on the basis of a cofactor requirement or loss of an essential enzyme. Evolution of hydr...

متن کاملParameters Affecting Solvent Production by Clostridium pasteurianum.
The effect of pH, growth rate, phosphate and iron limitation, carbon monoxide, and carbon source on product formation by Clostridium pasteurianum was determined. Under phosphate limitation, glucose was fermented almost exclusively to acetate and butyrate independently of the pH and growth rate. Iron limitation caused lactate production (38 mol/100 mol) from glucose in batch and continuous cultu...
