1-Butanol is a large-volume, intermediate chemical with favorable physical and chemical properties for blending with or directly substituting for gasoline. The per-volume value of butanol, as a chemical, is sufficient for investing into the recommercialization of the classical acetone-butanol-ethanol (ABE) (E. M. Green, Curr. Opin. Biotechnol. 22:337-343, 2011) fermentation process. Furthermore...

• The migration of 1-butanol caused the improper curing an epoxy-PU system. 1-Butanol has a two hundred times higher reaction rate than polyol reactant. 2-Butanol helps to improve hardness development Curing coatings under solvent evaporation-suppressed conditions, can lead trapping solvents and subsequent into mid- or topcoats in multilayer coating Such migrations may have adverse effects on m...

This study evaluated the in vitro antioxidative activity of Khaya senegalensis extracts and inhibitory effects of some sol vent fractions on a-glucosidase and a-amylase activities. The stem bark, root and leaf samples of the plant were sequentially extracted with ethyl acetate, ethanol and water and then tested for antioxidative activity. Our findings revealed that the ethanolic extract of the ...

BACKGROUND Butanol is regarded as an advanced biofuel that can be derived from renewable biomass. However, the main challenge for microbial butanol production is low butanol titer, yield and productivity, leading to intensive energy consumption in product recovery. Various alternative separation technologies such as extraction, adsorption and gas stripping, etc., could be integrated with aceton...

BACKGROUND Butanol production directly from CO2 in photosynthetic cyanobacteria is restricted by the high toxicity of butanol to the hosts. In previous studies, we have found that a few two-component signal transduction systems (TCSTSs) were differentially regulated in Synechocystis sp. PCC 6803 after butanol treatment. RESULTS To explore regulatory mechanisms of butanol tolerance, in this wo...
