Saccharomyces cerevisiae has increasingly been engineered as a cell factory for efficient and economic production of fuels and chemicals from renewable resources. Notably, a wide variety of industrially important products are derived from the same precursor metabolite, acetyl-CoA. However, the limited supply of acetyl-CoA in the cytosol, where biosynthesis generally happens, often leads to low ...

Methanolic extract of Jasminum mesnyi Hance leaves having antidiabetic activity was subjected to fractionation to obtain antioxidant and antihyperglycemic rich fraction. Different concentrations of ethyl acetate and n-butanol fractions were subjected to antioxidant assay by DPPH method, nitric oxide scavenging activity and reducing power assay. The fractions showed dose dependent free radical s...

Ruthenium complexes with tetradentate PNNP donor ligands demonstrate a marked change in selectivity compared to analogous bis bidentate PN Guerbet catalysis, producing mixtures of n-butanol (17 %), sec-butanol (14 %) and ethyl acetate (66 rather than the usual 90 %+ n-butanol. Tridentate PNP ruthenium such as [Ru(H)(Cl)(CO)(Ph2PCH2CH2NHCH2CH2PPh2)] also produce and, optimized conditions (120 °C...

densities and excess molar volume of the binary and ternary mixtures formed by nbutylacetate+ 1-butanol + 1,2-butanediol were measured at (298.15, 303.15, and 308.15) k forthe liquid region and at ambient pressure (81.5) k pa , for the whole composition range. theexcess molar volumes,vme and excess partial molar volume vie ,were calculated fromexperimental densities.the excess molar volumes are...

The Ni/P ratio of nickel phosphide has an important effect on the catalytic performance toward deoxygenation fatty acids to biofuel. Ni12P5 cluster is preferred model catalyst with butyric acid as reactant palmitic acid. mechanism over been theoretically investigated at GGA-PBE/DSPP, DNP level in dodecane solution. From acid, hydrodehydration predominated form n-butanal. Then, from n-butanal, l...

In this study, the in vivo effect of the crude extract and n-butanol and aqueous residual fractions of Baccharis articulata (Lam.) Pers. on serum glucose levels, insulin secretion and liver and muscle glycogen content, as well as in vitro action on serum intestinal disaccharidase activity and albumin glycation were investigated. Oral administration of the extract and fractions reduced glycemia ...

In this study, microemulsions of the chiral surfactant polysodium N-undecenoyl-D-valinate (poly-D-SUV) was utilized for enantiomeric separation by investigating two approaches using polymeric chiral surfactant in microemulsion electrokinetic chromatography (MEEKC). In the first approach, poly-D-SUV was used as an emulsifier surfactant along with 1-butanol and n-heptane. Enantioseparation of ani...

Objective(s) In the present study, the differences in the relaxant effects of aqueous, ethyl acetate and n-butanol fractions of Rosa damascena on tracheal smooth muscle of guinea pigs were examined. Materials and Methods The relaxant effects of three cumulative concentrations of each fraction (0.1, 0.2 and 0.4 g%) in comparison with saline and three cumulative concentrations of theophylline ...
