Ghattas, Ann-Kathrin published the artcileAnaerobic biodegradation of (emerging) organic contaminants in the aquatic environment, Quality Control of 117-96-4, the main research area is review emerging organic contaminant anaerobic biodegradation biol wastewater treatment; Anaerobic biodegradation; Biocides; Complex multifunctional contaminants (CMCs); Emerging organic contaminants (EOCs); Pesticides; Pharmaceuticals; Simple mono- or oligofunctional contaminants (SMOCs); Transformation.

Although strictly anaerobic conditions prevail in several environmental compartments, up to now, biodegradation studies with emerging organic contaminants (EOCs), such as pharmaceuticals and personal care products, have mainly focused on aerobic conditions. One of the reasons probably is the assumption that the aerobic degradation is more energetically favorable than degradation under strictly anaerobic conditions. Certain aerobically recalcitrant contaminants, however, are biodegraded under strictly anaerobic conditions and little is known about the organisms and enzymic processes involved in their degradation This review provides a comprehensive survey of characteristic anaerobic biotransformation reactions for a variety of well-studied, structurally rather simple contaminants (SMOCs) bearing one or a few different functional groups/structural moieties. Furthermore it summarizes anaerobic degradation studies of more complex contaminants with several functional groups (CMCs), in soil, sediment and wastewater treatment. While strictly anaerobic conditions are able to promote the transformation of several aerobically persistent contaminants, the variety of observed reactions is limited, with reductive dehalogenations and the cleavage of ether bonds being the most prevalent. Thus, it becomes clear that the transferability of degradation mechanisms deduced from culture studies of SMOCs to predict the degradation of CMCs, such as EOCs, in environmental matrixes is hampered due the more complex chem. structure bearing different functional groups, different environmental conditions (e.g. matrix, redox, pH), the microbial community (e.g. adaptation, competition) and the low concentrations typical for EOCs.

Ma, Wei published the artcileIron-Catalyzed Anti-Markovnikov Hydroamination and Hydroamidation of Allylic Alcohols, COA of Formula: C8H11NO, the main research area is allylic alc iron catalyst anti Markovnikov hydroamination hydroamidation.

Hydroamination allows for the direct access to synthetically important amines. Controlling the selectivity of the reaction with efficient, widely applicable, and economic catalysts remains challenging, however. This paper reports an iron-catalyzed formal anti-Markovnikov hydroamination and hydroamidation of allylic alcs., which yields γ-amino and γ-amido alcs., resp. Homoallylic alc. is also feasible. The catalytic system, consisting of a pincer Fe-PNP complex (1-4 mol %), a weak base, and a nonpolar solvent, features exclusive anti-Markovnikov selectivity, broad substrate scope (>70 examples), and good functional group tolerance. The reaction could be performed at gram scale and applied to the synthesis of drug mols. and heterocyclic compounds When chiral substrates are used, the stereochem. and enantiomeric excess are retained. Further application of the chem. is seen in the functionalization of amino acids, natural products, and existing drugs. Mechanistic studies suggest that the reaction proceeds via two cooperating catalytic cycles, with the iron complex catalyzing a dehydrogenation/hydrogenation process while the amine substrate acts as an organocatalyst for the Michael addition step.

Choo, Kenny S. O. published the artcileAroma-volatile profile and its changes in Australian grown black Perigord truffle (Tuber melanosporum) during storage, Category: isoquinoline, the main research area is Tuber acetone acetaldehyde toluene formic acid 2 butenal Australia.

Black Perigord truffle (Tubermelanosporum) is one of the most expensive fungi in the world that appreciated by gourmets. Studies have indicated the impact of growing location and soil microorganisms on the aroma profile of truffle. The aroma profile of West Australian black Perigord truffle (Tuber melanosporum) has not been previously reported, which was studied over a 14 day storage period. Sixty-four compounds were identified in all truffle samples. Significant changes (P > 0.05) were observed in 11 key volatiles (carbon dioxide, acetaldehyde, 2-butanone, 3-methyl-1-butanal, toluene, 2-butenal, formic acid 2-Me Bu ester, 3-methyl-1-butanol, 6-methyl-2-heptanol, 3-octanol and DMSO) over time. Comparison of these results against published aroma profile of European grown black Perigord truffle identified number of significant similarities and differences were also detected. DMSO, a compound previously identified in European grown white truffle (Tuber magnatum), was detected. Principle component anal. (PCA) showed that the major changes in the truffle aroma profile took place in the first 7 days of storage.

Jie, Yu published the artcileIdentification of Key Volatiles Differentiating Aromatic Rice Cultivars Using an Untargeted Metabolomics Approach, Application In Synthesis of 151-10-0, the main research area is Oryza aromatic cultivar metabolomics volatile compound; acetoin; aromatic rice; differential metabolites.

Non-aromatic rice is often sold at the price of aromatic rice to increase profits, seriously impairing consumer experience and brand credibility. The assessment of rice varieties origins in terms of their aroma traits is of great interest to protect consumers from fraud. To address this issue, the study identified differentially abundant metabolites between non-aromatic rice varieties and each of the three most popular aromatic rice varieties in the market using an untargeted metabolomics approach. The 656 metabolites of five rice grain varieties were determined by headspace solid-phase extraction gas chromatog.-mass spectrometry, and the multivariate analyses were used to identify differences in metabolites among rice varieties. The metabolites most differentially abundant between Daohuaxiang 2 and non-aromatic rice included 2-acetyl-1-pyrroline and acetoin; the metabolites most differentially abundant between Meixiangzhan 2 and non-aromatic rice included acetoin and 2-methyloctylbenzene,; and the metabolites most differentially abundant between Yexiangyoulisi and non-aromatic rice included bicyclo[4.4.0]dec,1-ene-2-isopropyl-5-methyl-9-methylene and 2-methylfuran. Overall, acetoin was the metabolite that was most differentially abundant between the aromatic and non-aromatic rice. This study provides direct evidence of the outstanding advantages of aromatic rice and acts a reference for future rice authentication processes in the marketplace.
