The use of genetically engineered microorganisms such as bacteria or yeasts as live vehicles to carry out bioconversion directly in the digestive environment is an important challenge for the development of innovative biodrugs. A system that mimics the human gastrointestinal tract was combined with a computer simulation to evaluate the survival rate and cinnamate 4-hydroxylase activity of a rec...

Green and effective synthesis of flavor esters is a long-term interest in food, cosmetic pharmaceutical industries. Here, an immobilized lipase microarray was prepared by immobilizing CSL on hydrophobically modified ordered mesoporous silicon ([email protected]8) for the enzymatic production cinnamic with different flavors. The results showed that [email protected]8, immobilization capacity 249...

The dinuclear title compound, [Nd(2)(C(9)H(7)O(3))(6)(C(10)H(8)N(2))(2)]·2C(10)H(8)N(2)·2H(2)O, was synthesized under hydro-thermal conditions. The centrosymmetric complex consists of two nine-coordinated Nd(3+) cations, six 3-hy-droxy-cinnamate anions and two chelating 2,2'-bipyridine mol-ecules. The coordination geometry around the cations can be best described as distorted tricapped trigonal...

ABSTRACT Carbon-chain anions were recently detected in the interstellar medium. These very reactive species are used as tracers of physical and chemical conditions a variety astrophysical environments. However, local thermodynamic equilibrium generally not fulfilled these Therefore, collisional well radiative rates needed to accurately model observed emission lines. We determine this work state...

Bioassay-guided fractionation of a CH(2)Cl(2)-MeOH extract of the aerial parts of Albizia inundata resulted in the isolation of two new natural oleanane-type triterpene saponins {3-O-[α-L-arabinopyranosyl(1→6)]-2-acetamido-2-deoxy-β-D-glucopyranosyl oleanolic acid (1) and 3-O-[α-L-arabinopyranosyl(1→2)-α-L-arabinopyranosyl(1→6)]-2-acetamido-2-deoxy-β-D-glucopyranosyl acacic acid lactone (2)} al...

Context. Carbon chemistry plays a pivotal role in the interstellar medium (ISM) but even the synthesis of the simplest hydrocarbons and how they relate to polycyclic aromatic hydrocarbons (PAHs) and grains is not well understood. Aims. We study the spatial distribution and chemistry of small hydrocarbons in the Orion Bar photodissociation region (PDR), a prototypical environment in which to inv...
