In addition to achieving a high productivity, a major advantage of immobilized cell technology (and cell recycle) is that cell mass is not washed out at high flow rates.An early report on adsorption (biofilm formation) of cells of,Following the above reports, an intensive study was performed on biofilm formation using,It is interesting that some supports accumulated greater cell concentrations (,Butanol production in various types of reactor systems has been intensively studied (,Among the various types of reactors used for butanol production, adsorbed cell biofilm reactors (cells adsorbed onto bonechar and clay brick) offered the highest reactor productivities ranging from 6.5 (,We use cookies to help provide and enhance our service and tailor content and ads. As a result, some degree of success was achieved in numerous countries when bioconversion programs involving alcohol fuel production were examined. Its isomers include isobutanol, 2-butanol, and tert-butanol. Production of butanol was discovered by Pasteur in 1861. The following table breaks down where n-Butanol is used to

Continuously rising prices and increased dependence on foreign fuel have been major driving factors for the increased interest in butanol fermentation as butanol could potentially be used as a motor fuel replacement. Un Butanol algal produit en recyclant les eaux usées. Butanol derivatives are used in shaving products and shampoos, as well as detergents and soaps.

However, constant conflicts in the oil supply regions and rising oil prices have reminded the world that alternate energy sources should be sought for future energy independence. As a result of research intensification, a number of problems associated with this fermentation were identified including cost-ineffective recovery of butanol by traditional recovery technology (distillation), low butanol concentration in batch reactor (<20 g l.In author’s opinion, research activities slowed during 1990s due to reduction or stabilization of gasoline prices. Increased oil prices in 1973 resulted in a revival of research activities on a number of fermentations, including ethanol and butanol, with a long-range view toward becoming less dependent on foreign oil.
n-Butanol or n-butyl alcohol or normal butanol is a primary alcohol with a 4-carbon structure and the chemical formula C4H9OH.

The process of butanol absorption can decrease the concentration of butanol in the broth, while the final release will form a final butanol solution with high concentration. C'est un solvant populaire, par exemple pour la nitrocellulose. As a result of recent technological developments in butanol fermentation and recovery, Dupont (United States) and British Petroleum (United Kingdom) have announced their plans to commercialize butanol production from bio-based substrates.For strain improvement, some advances have been achieved by classical methods such as recursive mutagenesis.
