Parameters 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...
متن کاملProduction of Clostridium pasteurianum in a defined medium.
A method for the growth of Clostridium pasteurianum in a 140-liter (total capacity) stainless-steel vessel is described. By preventing the pH value from falling below 5.6, the growth of cultures was prolonged. Larger amounts of the carbon source (sucrose) and the nitrogen source (ammonium ion) were supplied and consumed, and cell yields of up to 5.56 g (dry weight) per liter were obtained. The ...
متن کاملRole of Chemotaxis in Solvent Production by Clostridium acetobutylicum.
The motility of Clostridium acetobutylicum has been investigated during a typical batch fermentation process for solvent production. The motility is characterized by "runs" during the early phase of sugar utilization and acid production, but this changes to "tumbles" during the onset of solventogenesis. Sugars and undissociated acetic and butyric acids have been shown to be attractants for the ...

متن کاملComplete Genome Sequence of the Nitrogen-Fixing and Solvent-Producing Clostridium pasteurianum DSM 525
Here, we report on the closed genome sequence of Clostridium pasteurianum DSM 525, which is an anaerobic, Gram-positive and endospore-forming organism. C. pasteurianum can fix N2 and produce solvents such as butanol and 1,3-propanediol from carbohydrates. The genome consists of a single 4,350,673-bp replicon.
