The impossibility of determination of which variables are really significant in the both experimental design occurs because in the both cases the numbers of helpful run was halved with the not
butanol production on pH 8, 7 and 5.
On the other hand, as a result of the decrease of total permeation flux, the partial flux of both
butanol and water also decreased with the increase of ethanol concentration in coagulation bath from (15 to 35%) in the order of M1> M3> M2 (as shown in Figs.7 and 8).
Para el
butanol, a 140[grados]C, se encontro la presencia de 3 picos representativos de la fraccion hidrocarburos C4 a 5 minutos.
In one recent study, Qureshi, ARS chemist Badal Saha, and ARS microbiologist Mike Cotta evaluated the effectiveness of SHFR in fermenting barley straw plant sugars into
butanol. They pretreated the barley straw to release the plant sugars, which created a broth called a "hydrolyzate" that could be fermented into
butanol.

The second phase is the solventogenic phase during which acids are reassimilated and used in the production of acetone,
butanol, and ethanol.
En este punto los acidos son reconsumidos y convertidos en acetona y
butanol, permitiendo a la celula estar activa metabolicamente por mas tiempo al incrementar el pH externo.
The Saudi
Butanol Company, which will produce
butanol to support the growth of the paints and coatings industry in Saudi Arabia, will be located at Tasnee Petrochemicals Complex in Jubail Industrial City and operated by Tasnee.
Meanwhile, Cobalt's technology will demonstrate that these sugars can also produce
butanol." www.cobalttech.com; www.americanprocess.com.
The scientists discovered a bacterial strain, named "TU-103," that uses paper to make
butanol, a biofuel that can replace gasoline.
Acetone
butanol ethanol (ABE) fermentation by Clostridium acetobutylicum is one of the oldest known industrial fermentations.
