Role 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 کاملFermentation of Oil Palm Frond Juice for Solvent production Using Clostridium acetobutylicum (ATCC4259)
Abundant sources of palm oil based biomass provide an impetus for the sustainable generation of biofuel. Biomass such as palm oil agro-plantation waste are emerging as a promising sources of renewable liquid fuels, hence, in order to investigate the potentials of using oil palm frond juice (OPF) as feedstock for solvent production ,nutrient and sugar contents analysis was examined. A total solv...
متن کاملIntracellular Conditions Required for Initiation of Solvent Production by Clostridium acetobutylicum.
We investigated the intracellular physiological conditions associated with the induction of butanol-producing enzymes in Clostridium acetobutylicum. During the acidogenic phase of growth, the internal pH decreased in parallel with the decrease in the external pH, but the internal pH did not go below 5.5 throughout batch growth. Butanol was found to dissipate the proton motive force of fermentin...
متن کاملSubstrate-induced production and secretion of cellulases by Clostridium acetobutylicum.
Clostridium acetobutylicum ATCC 824 is a solventogenic bacterium that grows heterotrophically on a variety of carbohydrates, including glucose, cellobiose, xylose, and lichenan, a linear polymer of beta-1,3- and beta-1,4-linked beta-D-glucose units. C. acetobutylicum does not degrade cellulose, although its genome sequence contains several cellulase-encoding genes and a complete cellulosome clu...
متن کاملBacteriocin production by Clostridium acetobutylicum in an industrial fermentation process.
High titers of a noninducible bacteriocin were produced by Clostridium acetobutylicum in a molasses fermentation medium used for the industrial production of solvents. Release of the bacteriocin towards the end of the exponential growth phase was accompanied by lysis of the culture and inhibition of the production of solvents. The producer cells were sensitive to the bacteriocin, which only aff...
