Oxygen and nitrate enhanced in situ bioremediation of an oil -contaminated salt marsh
… of short chain (SC) and long chain (LC) aliphatics and aromatics, abundance of oil-degrading bacteria, nutrients and Spartina alterniora growth were monitored.</p><p>Results indicated that natural attenuation (control) significantly reduced the TPH. The overall (1998--1999) degradation …

Genetic characterization of Rhodococcus rhodochrous ATCC BAA-870 with emphasis on nitrile hydrolysing enzymes
… a wide substrate range, with activity against aliphatics, aromatics, and aryl aliphatics, and enantioselectivity towards beta substituted nitriles and beta amino nitriles, compounds that have potential applications in the pharmaceutical industry. This makes R. rhodochrous ATCC BAA-870 …

Investigation of the Steric and Electronic Properties of 3-Iminophosphine Ligands in Chelated Palladium Allyl Complexes for Use in the Regioselective Hydroamination of Allenes
… effective catalysis, as primary and secondary aliphatics and aromatic groups also decrease the catalytic activity. Highly basic imine moieties were also shown to decrease catalytic activity.

Microwave-assisted pyrolysis of HDPE using an activated carbon bed
… with the remainder primarily short-chain aliphatics. This oil was approximately three times lighter than that produced in the absence of catalyst, with a narrower range of molecular masses that matched those of the liquid transport fuels petrol and diesel (C5–C21). The non-condensable …

Assessing the role of soil chemoautotrophs in carbon cycling: An investigation into isotopically labelled soil microorganisms
… of PLFAs, protein/peptide, carbohydrates and aliphatics were observed. Finally, an attempt to mimic common agricultural practice was performed to measure soil chemoautotrophic activity. This demonstrated the capability of this approach to benefit carbon flux estimations and hopefully in the …

Characterizing the role of ATP-binding cassette transporters in triterpenoid wax bloom production
… with specificity for triterpenoids rather than aliphatics. Kalanchoe is a genus of succulent plants that vary in their ability to produce wax blooms, with some species producing the triterpenoid wax blooms of interest. Here, I investigated the role of ABC transporters in triterpenoid wax bloom …

I. Synthesis of Ascarosides for Chemical Biology Studies in Caenorhabditis elegans, II. A Photochemical Approach to Delavayine, and III. Remote Hydroxylation by Radical Translocation and Polar Crossover
… and 1,7-hydrogen atom transfers from unactivated aliphatics. The resulting radicals were then oxidized by redox (or photoredox) catalysis to form a carbocation that was ultimately trapped by water or methanol. After loss of a proton, successfully hydroxylated or methoxylated products were isolated …

Cloning and Characterization of the dominant Inhibitor of Wax 1 (Iw1) gene in polyploid wheat
… that only a discrete type of wax, the β–diketone aliphatics, is being inhibited by Iw1.

CONVERSION OF METHANOL AND LIGHT OLEFINS TO GASOLINE OVER A SHAPE SELECTIVE CATALYST ZSM-5
… C(,2)-C(,5) olefins (,aromatics) Monomethyl aliphatics predominate over both straight-chain and dimethyl hydrocarbons. Aromatics consist mainly of toluene and xylene mixtures. At 368(DEGREES)C, compositions of butene isomers are in thermodynamic equilibrium, over the range of residence times …

Boron-Mediated Semireduction of Alkynoic Acid Derivatives
… electron-rich or deficient aryls, and aliphatics using optimized reaction conditions and produced a library of (E)-cinnamamides in 31 – 98% yield with >99:1 E:Z stereoselectivity. Deuterium labeling studies suggest that hydrogens on the α- and β-carbon come from pinacolborane and the …

Taxonomical use of floral scent data in apomictic taxa of Hieracium and Sorbus derived from hybridization
… mainly of sesquiterpenes, monoterpenes, aliphatics and aromatics. In the flower scent of Sorbus besides these substances also nitrogene-containing substances were found. In Hieracium (both subgenera) as well as in Sorbus, taxa of hybrid origin showed a mixed scent pattern compared with …

Thermo-analytical and physico-chemical characterisation of organoclays and polymer-clay nacomposites.
… to the formation of linear, branched and cyclic aliphatics and aromatics from the feedstock surfactants.Intra-series comparisons of different organoclays showed that as the alkyl chain length of the n-alkylammonium surfactants was increased the concentration of thermal desorption products at …

Role of Fatty Acid omega-Hydroxylase 1 and Abscisic Acid in Potato Tuber Suberin Formation
Suberin is a complex biopolymer composed of two distinct but covalently-linked domains. The first domain is composed of polymerized phenolic monomers, whereas the second domain is predominately fatty acid derivatives esterified with glycerol. Deposited in specialized cells during development or in …
