Male and female true armyworm moths, Pseudaletia unipuncta (Haworth), were captured in traps baited with the combination of acetic acid and 3-methyl-1-butanol and placed near fields of corn ( Zea mays ). In a comparison of these chemicals presented individually and together, significantly greater numbers of moths were captured in traps baited with acetic acid and 3-methyl-1-butanol, compared to...

IR-visible sum-frequency generation (IV-SFG) vibrational spectroscopy and a molecular dynamics (MD) simulation were used to study the local layering order at the interface of 1-butanol-d9 and 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim]PF6), a room-temperature ionic liquid (RTIL). The presence of a local non-polar layer at the interface of the two polar liquids was successfully demon...

Oligodeoxynucleotides are among the most useful tools in modem molecular biology. Phosphoramidite-synthesized oligonucleotides require a final reaction step with concentrated ammonia to effect their complete deprotection. The resulting organic by-products, e.g. benzamides, need to be removed from the oligonucleotides before the latter may be used in various enzymatic processes (1). Typically, t...

This investigation sought to characterize biochemically the tumor-specific transplantation antigens (TSTA) expressed on the cell surface of a panel of chemically induced fibrosarcomas of CSH/HeJ mice. Results suggest a uniform antigenic framework upon which individual specificities are superimposed. The anti gens expressed by the 3-methylcholanthrene-induced fibrosar comas MCA-D, MCA-F, and MCA...

Microbial production of higher alcohols from renewable feedstock has attracted intensive attention thanks to its potential as a source for next-generation gasoline substitutes. Here we report the discovery, characterization and engineering of an endogenous 1-butanol pathway in Saccharomyces cerevisiae. Upon introduction of a single gene deletion adh1Δ, S. cerevisiae was able to accumulate more ...

adsorption of 1-butanol, phenol, and p-nitrophenol on activated carbon havebeen studied. the results were used to testifying the validity of different modelsbased on thermodynamic principles: freundlich, langmuir and henry isotherms.the maximum capacity of adsorbent for three compounds was determined, theconstants of equilibrium were determined by freundlich isotherm and virialisotherm expressi...

The human liver alpha alpha alcohol dehydrogenase exhibits a different substrate specificity and stereospecificity for secondary alcohols than the human beta 1 beta 1, and gamma 1 gamma 1 or horse liver alcohol dehydrogenases. All of the enzymes efficiently oxidize primary alcohols, but alpha alpha oxidizes secondary alcohols far more efficiently than human beta 1 beta 1 and gamma 1 gamma 1 or ...

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...
