The objective of this study was to investigate the effects of four com. lactic acid bacteria (LAB), namely L. acidophilus, L. casei, L. helveticus and L. plantarum, on the phenolic profiles, antioxidant capacities and flavor profiles of jujube juices prepared from two crop varieties (Ziziphus Jujuba cv. Muzao and Hetian). Results showed that both jujube juices were excellent matrixes for LAB growth with more than 11 log CFU/mL of viable counts at the end of fermentation LAB fermentation dramatically increased total phenolic content, while decreased total flavonoid content of jujube juices. However, antioxidant capacities based on DPPH and FRAP methods were significantly improved by LAB fermentation and pos. correlated with caffeic acid and rutin contents. Furthermore, a total of 74 volatile compounds were identified and increased in total content by LAB fermentation, which resulted in 22 and 19 new flavor volatiles formation in Muzao juice and Hetian juice, resp.

Zhu, Man; Chen, Yao; Zhao, Ninghui; Bai, Hua; Zhang, Keqin; Huang, Xiaowei published the artcile< Multiple olfactory pathways contribute to the lure process of Caenorhabditis elegans by pathogenic bacteria>, SDS of cas: 104-76-7, the main research area is Caenorhabditis multiple olfactory pathway lure process pathogenic bacteria; B. nematocida B16; Caenorhabditis elegans; attractant; chemotaxis; host; olfactory signaling pathway; pathogenic bacteria.

Abstract: Chemosensation is indispensable for the survival of Caenorhabditis elegans to discriminate food and pathogenic bacteria in their living environment. Food-like odors emitted by the pathogen Bacillus nematocida B16 for trapping its hosts and an olfactory signaling pathway responsible to sense the attractant 2-heptanone were identified in our previous study. Here, we further explore how the worms recognize the attractive mols. indole and 2-Et hexanol, which have different chem. properties and modest nematode-luring ability. We show that the chemotaxis toward indole and 2-Et hexanol requires the G protein-coupled receptors encoded by str-193 on AWC and str-7 on AWA. In a further genetic screen for downstream effectors in olfactory signaling cascades, the Gα subunit GSA-1, guanylyl cyclase ODR-1 and DAF-11 and the cGMP-gated channel TAX-2/TAX-4 were found to be necessary for indole sensation, whereas the TRPV channels OSM-9/OCR-2 and the PLC pathway activated by GPA-6 are responsible for the detection of 2-Et hexanol. Altogether, our current work further clarifies the distinct olfactory signaling pathways through which C. elegans senses different chems. and is lured by B. nematocida B16, improving our comprehensive understanding of the mechanisms by which bacterial pathogens effectively infect their hosts.

Valihura, K. V.; Larina, O. V.; Kyriienko, P. I.; Balakin, D. Yu.; Soloviev, S. O. published the artcile< Influence of Modifying Additives of Lanthanum and Cerium Oxides on Acid-Base Characteristics and Catalytic Properties of MgO-Al2O3 Systems in the Process of Gas-Phase Conversion of Ethanol to 1-Butanol>, Formula: C8H18O, the main research area is butanol ethanol lanthanum cerium magnesium aluminum oxide catalytic property.

The process of ethanol condensation to 1-butanol in the presence of MgO-Al2O3 systems modified with lanthanum and cerium oxide additives was studied. It is shown that MgO-Al2O3 doping with lanthanum and cerium oxides leads to an increase in the total concentration of acid and basic sites on the surface of the catalysts. It was found that increasing the concentration of basic sites for La- and Ce-containing samples promotes an increase in the yield of acetaldehyde but does not lead to an increase in the yield of 1-butanol due to a decrease in the number of aldol condensation sites. Increasing the concentration ratio of basic and acid sites of the surface helps to increase the productivity of the catalyst for 1-butanol.

Zharkov, Mikhail N.; Arabadzhi, Svetlana S.; Kuchurov, Ilya V.; Zlotin, Sergei G. published the artcile< Continuous nitration of alcohols in a Freon flow>, HPLC of Formula: 104-76-7, the main research area is alc nitration continuous Freon flow.

The first ever installation for continuous nitration in a liquefied gas mobile phase was developed. The installation was used to convert 2-ethylhexan-1-ol, diethylene glycol, and glycerol into their corresponding nitro esters. The starting compounds were treated with a 10% excess of dinitrogen pentoxide in liquefied 1,1,1,2-tetrafluoroethane (TFE) medium. The flow reactions proceeded at room temperature and ≤10 bar pressure with excellent conversion and selectivity. An important feature of the developed procedure is TFE recycling which prevents its release into the atm. The proposed approach for nitro esters flow production outperforms the known batch-type analogs in terms of having a far better specific productivity (by two orders of magnitude), reduced fire and explosion risks, and less pronounced neg. impact on the environment. The enumerated advantages along with equipment availability lay the foundation for the development of a highly efficient nitration technol., which is characterized by reduced amounts of waste by employing a TFE medium.

Luna, F. Murilo T.; Salmin, Davi Costa; Santiago, Vanessa S.; Maia, Francisco J. N.; Silva, Francisco O. N.; Mazzetto, Selma E.; Cavalcante, Celio L. Jr. published the artcile< Oxidative stability of acylated and hydrogenated ricinoleates using synthetic and natural antioxidants>, Name: 2-Ethylhexan-1-ol, the main research area is acylated hydrogenated ricinoleate antioxidant thermo oxidative stability.

As increasing environmental policies constrains are imposed, the demand for biodegradable products also increases. Although vegetable oils present some properties that favor its use for formulation of a bio-based lubricant, its poor resistance to oxidation hinders its application as such. In this study, the thermo-oxidative stability of bio-based products was compared to petroleum-based lubricants and vegetable oils through the PetroOXY method. Chem. modifications in the ricinoleic acids were carried out using long-chain alcs. in esterification reactions. Acetates were obtained from ricinoleates with and without hydrogenation steps. Addnl., com. antioxidants and phenolic compounds (saturated and unsaturated cardanol) obtained from cashew nut shell liquid were added to the synthesized samples with higher induction times. The results show that the chem. modified bio-based products exhibited improved oxidative stability (up to 6 times) and depressed pour point (-42°C) when compared to pure castor oil. Overall, the addition of antioxidants increased from 6 to 20 times the oxidative stability of the bio-based products. Pr gallate and saturated cardanol showed higher efficiency for retarding the oxidative process of bio-based samples than the com. antioxidants.

This work demonstrates the possibility of using pelargonic acid (PA) esters as solvents for vegetable-based varnishes. First, PA was efficiently produced through a chemocatalytic cleavage of oleic acid, practicing an optimized scale-up of previously developed conditions. PA was then esterified with several alcs. ROH (R = Me, i-Pr, n-Bu, n-Hex, 2-ethylhexyl, and sec-octyl) and the products were formulated with a com. rosin (Phenolic Modified Rosin Esters). Dynamic light scattering (DLS) measures and determination of rheol. parameters of the corresponding varnishes disclosed their suitability for applications in offset, coldset, heatset printing inks, and coatings. Furthermore, inks obtained were used to efficiently produce preliminary industrial offset prints.

Fresh and grilled eel were investigated with respect to their volatile compounds and different fingerprinting techniques. An electronic nose (e-Nose) was applied to distinguish the odor between fresh and grilled eels. Purge and trap (P&T) and solvent-assisted flavor evaporation (SAFE) method were used to extract volatile compounds and further analyzed by a gas chromatog. combined with quadrupole mass spectrometry (GC-MS) and a two-dimensional gas chromatog. combined with hybrid quadrupole time-of-flight mass spectrometry (GC × GC-QTOF). SAFE extracted more ketone, alc. and high boiling volatiles in eels than P&T. Considering some distinct compounds extracted by P&T, a P&T and SAFE combined method was chosen. There were 155 volatiles detected in fresh and grilled eels, 93 volatiles were identified. Due to the higher peak capacity, GC × GC-QTOF detected 39 compounds more than GC-MS. The key characteristic volatiles of grilled eel were Me Pr disulfide, di-Me trisulfide, heptane, octane, and camphene. Volatile fingerprinting can be a reference benchmark for identification and quality appraisal of fresh and grilled eel products.
