Abstract:

Três amostras da concentração pesada natural das areias lombares superiores da praia de S.Torpes foram analisadas por microscopia, MEV e microssonda, a fim de caracterizar a composição mineralógica dos minerais do minério. Devido à forte granulometria homogénea, a areia foi apenas dividida em duas fracções, acima e abaixo da peneira de 125 microns. Cada fracção foi sujeita a separação magnética por mão magnética e líquido pesado (bromoforme). A fracção paramagnética foi submetida a um electroíman de Frantz. As fracções magnéticas e paramagnéticas foram estudadas em microscopia de reflexão, SEM e microssondas electrónicas. Estas técnicas mostraram que a fracção pesada destas areias é composta em média por magnetite (71%), ilmenite (12%), hematite (8%) e grãos mistos (9%). Os aspectos textuais das três principais composições minerais, bem como a sua composição química e fórmula estrutural foram ainda mais caracterizados. Identificámos também pequenas quantidades de monazite e minerais de alteração (rutilo, psudorutilo, ilmenorutilo e titanite) e sulfuretos, tudo em quantidades muito pequenas. Foi possível determinar a composição "média" mineralógica da areia combinando os resultados deste estudo com o estudo de Pombo et al. (2006).

Abstract:

Sulfuretin glucosides are important sources of innovative drugs. However, few glucosides of sulfuretin have been observed in nature. Therefore, it is urgent to diversify sulfuretin glycosides. Herein, glycosyltransferase (GT)-catalyzed glycodiversification of sulfuretin was achieved. Specifically, a flavonoid GT designated as OcUGT1 was used as a biocatalyst for the glucosylation of sulfuretin with UDP-Glc. The OcUGT1-assisted glucosylation of sulfuretin yielded ten glycosylated products, including three monoglucosides, five diglucosides and two triglucosides. The three monoglucosides were thus identified to be sulfuretin 3′-, 4′- and 6-glucoside according to HR-ESI-TOFMS data and their coelution with respective standards. A major diglucoside was assigned as sulfuretin 4′,6-diglucoside by HR-ESI-TOFMS in conjunction with NMR analysis. The exact structure of the other four diglucosides was not well characterized due to their trace amount. However, they were reasonably inferred as sulfuretin 3′,6-diglucoside, sulfuretin 3′,4′-diglucoside and two disaccharide glucosides. In addition, the structural identification of the remaining two triglucosides was not performed because of their small amount. However, one of the triglucosides was deduced to be sulfuretin 3′,4′,6-triglucoside based on the catalytic behavior of OcUGT1. Of the ten sulfuretin glucosides, at least six were new compounds. This is the first time to obtain monoglucosides, diglucosides and triglucosides of sulfuretin simultaneously by a single glycosyltransferase.

Abstract:

Two coryneform bacteria were isolated from a penguin rookery soil sample collected in Antarctica, near the Indian station Dakshin Gangotri (strain Lz1yT), and from sea water from Kerguelen island, Antarctica (strain KGN15T). They have morphological and chemotaxonomic properties (peptidoglycan A4α type; major menaquinones MK-8, MK-9 and MK-10; predominant fatty acids anteiso-C15 : 0 and anteiso-C17 : 0) that are characteristic of members of the genus Arthrobacter. The isolates shared 97·8 % 16S rRNA gene sequence similarity to each other and were most closely related to Arthrobacter sulfureus (about 98·5 % sequence similarity). DNA–DNA hybridization experiments revealed 50 % relatedness between the isolates, while the levels of DNA–DNA relatedness between strains Lz1yT and KGN15 T and their phylogenetic relative, A. sulfureus, were respectively 54 and 12 %. Based on the above data and distinct phenotypic differences between the isolates and A. sulfureus, two novel species are proposed, Arthrobacter gangotriensis sp. nov. (type strain Lz1yT=DSM 15796T=JCM 12166T) and Arthrobacter kerguelensis sp. nov. (type strain KGN15T=DSM 15797T=JCM 12165T).

Abstract:

Rhus verniciflua Stokes (RVS) is a plant with a long history of medicinal use in Eastern Asia. RVS has been widely used to treat gastritis, stomach cancer and atherosclerosis. The cytotoxic effects of different solvent fractions from an RVS ethanol extract were measured in 11 human cancer cell lines. The study showed that the ethyl-acetate (EtOAC) fraction was the most cytotoxic. This fraction contains a number of phenolic compounds, and this phenolic-rich EtOAC fraction was particularly effective against gastric and breast cancer cells. A purified phenolic-rich EtOAC fraction (PPEF) had a stronger apoptotic effect on these cells. Liquid chromatography-mass spectrometry (LC-MS) analysis showed that the PPEF contained gallic acid, protocatechuic acid, fisetin, sulfuretin, butein and 8 unknown compounds. There were only small amounts of flavonoids: fisetin, sulfuretin and butein. The results showed that PPEF induces apoptosis only in gastric and breast cancer cell lines, but not in lung, colon or liver cancer cell lines. Therefore, PPEF may have a significant potential as an organ-specific anti-cancer agent.

Abstract:

On the basis of phenotypic, genotypic and chemotaxonomic characteristics, a novel species belonging to the genus Arthrobacter is described. A facultatively psychrophilic bacterium, strain AG31T, was isolated from an alpine ice cave. The aerobic, Gram-positive, non-spore-forming, non-motile strain exhibited a rod–coccus growth cycle and produced a yellow pigment. Good growth and phenol biodegradation occurred at a temperature range of 1–25 °C. Up to 10 mM phenol was utilized as a sole carbon source. Glucose was not assimilated. Analysis of the 16S rRNA gene revealed that strain AG31T represents a distinct lineage within the genus Arthrobacter, being most closely related to Arthrobacter sulfureus. The level of DNA–DNA relatedness to the type strain of A. sulfureus was 29·9 %. Anteiso-C15 : 0 was the predominant fatty acid (72 %). Strain AG31T exhibited A4α l-lys–l-Glu-type peptidoglycan and contained glucose as the only cell-wall sugar. MK-10 was the predominant menaquinone, and the polar lipid pattern consisted of phosphatidylglycerol, diphosphatidylglycerol, phosphatidylinositol and an unidentified glycolipid. Strain AG31T (=DSM 15454T=LMG 21914T) is assigned as the type strain of a novel Arthrobacter species, Arthrobacter psychrophenolicus sp. nov.

Abstract:

La toxicité des eaux usées du tannage au chrome et d'épilage-pelanage, avant et après traitement, a été évaluée par test Daphnia pulex. Cette évaluation a été déterminée à partir des équations de corrélation linéaires. Les résultats obtenus montrent que le tannage au chrome et l'épilage-pelanage présentent une toxicité élevée avec des valeurs des CI50 24h respectives de 0,15 et 3,36. Cette toxicité élevée pourrait être expliquée par la charge de ces effluents en chrome, en sulfures et en matière organique. Après traitement par précipitation chimique, la CI50 24h a connu une importante augmentation. Elle est passée de 0,15 à 26,58 et de 3,36 à 11,1 respectivement pour le tannage au chrome et l'épilage-pelanage. Par conséquent, ces effluents traités peuvent être classés comme rejets peu toxiques. Cette diminution de la toxicité est liée surtout à l'abattement des MES (95 %), de la DCO (55 %), de Cr (90 %) et des sulfures (50 %). Ce traitement a donc, un double intérêt; le premier est environnemental, le second est économique du fait de la possibilité de recyclage du chrome récupéré dans le tannage du cuir. En effet, l'application expérimentale du chrome dans le tannage a montré un résultat similaire à celui obtenu par le produit commercial. Ainsi, suite à une analyse technico-économique, le bénéfice réalisé par cette opération est estimé à 3112,50 $ par 1000 tonnes par an.

Abstract:

The [Formula: see text] (CZTS) thin film is a photovoltaics material with excellent photoelectric properties and has good potential applications. The CZTS thin films with different spin-coated layers and sulfurized temperatures were successfully prepared by a sol–gel spin-coating technique. The relationships of microstructure, surface morphology and processing parameters were studied using XRD, SEM and EDS. The results indicate that the grain size of the sample sulfurized at [Formula: see text]C was larger than that of the sample sulfurized at [Formula: see text]C. With increasing layers of spin, coatings, the films showed better crystalline structure. The sulfureted CZTS thin films prepared by six spin-coating possess uniform elemental distribution.

Using cadmium acetate and sodium sulfuret as Cd and S sources, CdS samples were synthesized by chemical precipitation method. The conditions of supersaturation and aging time had been investigated, which could influence the activity of CdS for photocatalytic degrading methyl orange. The products were characterized by X-ray powder diffraction and field emission scanning electron microscopy. The CdS samples synthesized under low supersaturation showed better photocatalytic activities. A phase transformation of hexagonal CdS to cubic CdS was observed when CdS precipitation aging and the presence of proper amount of hexagonal CdS should improve the photocatalytic performance of cubic CdS.

Abstract:

Sulfuretin (SFR), which is isolated from Rhus verniciflua , Toxicodendron vernicifluum, Dahlia, Bidens tripartite and Dipterx lacunifera , is one of the most important natural flavonoids. This compound is known to have numerous biological activities; among these, the antioxidant activity has not been thoroughly studied yet. In this study, the hydroperoxyl scavenging activity of SFR was examined by using density functional theory calculations. SFR is predicted to be an excellent HOO • scavenger in water at pH = 7.40 with k overall = 4.75 × 10 7 M −1 s −1 , principally due to an increase in the activity of the anionic form following the single-electron transfer mechanism. Consistently, the activity of the neutral form is more prominent in the non-polar environment with k overall = 1.79 × 10 4 M −1 s −1 following the formal hydrogen transfer mechanism. Thus, it is predicted that SFR exhibits better HOO • antiradical activity than typical antioxidants such as resveratrol, ascorbic acid or Trolox in the lipid medium. The hydroperoxyl radical scavenging of SFR in the aqueous solution is approximately 530 times faster than that of Trolox and similar to ascorbic acid or resveratrol. This suggests that SFR is a promising radical scavenger in physiological environments.

Abstract:

Two enterococcal strains LMG 16607T and LMG 16612 originating from sea water were analysed in a polyphasic taxonomic study. Both strains, assigned as Enterococcus sp. in the BCCM/LMG culture collection, possessed analogous protein profiles, but these were different from all other enterococcal species. 16S rRNA gene sequence analysis of one strain showed the highest similarity, 96·9–96·1 %, with its closest phylogenetic neighbours Enterococcus saccharolyticus, Enterococcus sulfureus, Enterococcus saccharominimus and Enterococcus italicus. Further genomic analysis by (GTG)5-PCR fingerprinting and sequence analysis of the housekeeping gene phenylalanyl-tRNA synthase (pheS) and distinct biochemical features confirmed that the two strains represent a novel enterococcal species for which the name Enterococcus aquimarinus sp. nov. is proposed. The type strain is LMG 16607T (=CCM 7283T).

Abstract:

The decomposition of sulfur hexafluoride (SF6) in overheated electric equipment at different temperature and humidity was simulated in the study. SF6 is significantly decomposed at 350°C. SF6 is more easily decomposed in high humidity than in low humidity. The concentrations of SF6 byproducts, such as sulfur dioxide (SO2), sulfureted hydrogen (H2S) and hydrofluoric acid (HF), in high humidity are much higher than those in low humidity. Moisture in electric equipment accelerates the decomposition of SF6. In order to insure the safety operation of electric equipment, moisture in the equipment should be strictly controlled. SF6 will be decomposed to format HF. The concentration of HF will decrease when its concentration increases up to a certain concentration. It may be because that HF was strongly corrosive and its corrosion to inner equipment made the concentration of HF decreasing.

Abstract:

The taxonomic positions of seven atypical Enterococcus strains, isolated from artisanal Italian cheeses, were investigated in a polyphasic study. By using 16S rRNA gene sequencing, DNA–DNA hybridization and intergenic transcribed spacer analysis, as well as by examining the phenotypic properties, the novel isolates were shown to constitute a novel enterococcal species. Their closest relatives are Enterococcus sulfureus and Enterococcus saccharolyticus, having a 16S rRNA gene sequence similarity of 96·7 %. This group of strains can be easily differentiated from the other Enterococcus species by DNA–DNA hybridization and by their phenotypic characteristics: the strains do not grow in 6·5 % NaCl, and they do not produce acid from l-arabinose, melezitose, melibiose, raffinose or ribose. The name Enterococcus italicus sp. nov. is proposed for this species, with strain DSM 15952T (=LMG 22039T) as the type strain.

Abstract:

A new 3-deoxyanthocyanin was isolated from the orange flowers of Cosmos sulphureus cultivar “Diabolo,” together with known aurone, chalcone, flavone, flavonol, and flavanone. The chemical structure of 3-deoxyanthocyanin was established as 5,7,2′,4′-tetrahydroxyflavylium 4′- O-β-d-glucopyranoside by chemical and spectroscopic methods including UV, FAB MS, and 1H and 13C nuclear magnetic resonance spectroscopy (NMR), and named as cosmonidin 4′- O-glucoside (1a). Other known flavonoids were characterized as sulfuretin 6- O-glucoside (2), butein 4′- O-glucoside (3), quercetin 3- O-glucoside (4), luteolin 7- O-glucuronide (5), and eriodictyol 7- O-glucuronide (6) by UV, liquid chromatograph - mass spectra (LC-MS), NMR, and high performance liquid chromatography comparisons with authentic samples. Anthocyanin, which 2′-position is hydroxylated, has not been reported until now. Compound (1a) was also found in other 10 C. sulphureus cultivars “Lamala Lemon,” “Sunrise,” “Dwarf Yellow,” “Cosmic Yellow,” “Carpet Gold,” “Mandarin,” “Cosmic Orange,” “Orange Flare,” “Cosmic Red,” and “Sunset.”

Abstract:

Four isolates, which were obtained from Belgian, Moroccan and Romanian dairy products, constituted a homogeneous but unidentified taxon after screening with whole-cell protein fingerprinting. Complete 16S rRNA gene sequence analysis classified representative strains in the genus Enterococcus. Highest sequence similarities of 98·6 and 98·0 % were obtained with the species Enterococcus sulfureus and Enterococcus saccharolyticus, respectively. Growth characteristics, biochemical features, tRNA intergenic length polymorphism analysis, DNA–DNA hybridization and DNA G+C contents of selected strains demonstrated that they represent a single, novel Enterococcus species. It differs phenotypically from other enterococci in characteristics commonly considered as typical of this genus: no growth in 6·5 % NaCl or 0·4 % sodium azide, and no acid production from a wide range of carbohydrates. The name Enterococcus saccharominimus sp. nov. is proposed for this novel species; the type strain (LMG 21727T=CCM 7220T) was isolated from contaminated pasteurized cow's milk.
