This study aimed at evaluating the quality of fig wines that co-fermented by three non-Saccharomyces. Four suitable ratios were selected for co-fermentation, and the fermentation performance of fig wines was compared with fig juice and the pure fermentation of Saccharomyces. High performance liquid chromatog. was used to analyze organic acids and mono-phenols in fig wines, and the amino acid analyzer was used to detect free amino acids. The results showed that fig wines fermented by non-Saccharomyces had higher contents of organic acids and mono-phenols. Head space solid phase microextraction method and analyzed by gas chromatog. mass spectrometry was used to detect 48 aroma compounds in fig wines, and the results revealed that co-fermentation by non-Saccharomyces could obtain up to 38 aroma compounds, which was superior to 30 substances obtained from fermentation by Saccharomyces. Principal component anal. was used to detect pos. correlations between samples and aroma compounds The results showed that there were significant differences in the aroma compounds in the different samples. Non-Saccharomyces played an important role in the aroma and flavor of fruit wine, and were used as an auxiliary starter culture to improve the effect of Saccharomyces fermentation The research on non-Saccharomyces in the literature was limited to the use of non-Saccharomyces alone for fermentation, and the fermentation performance was much worse than Saccharomyces. In this study, three non-Saccharomyces were selected for co-fermentation The result revealed that pleasant fig wine could be obtained by co-fermentation of non-Saccharomyces without a Saccharomyces starter culture, which provided a significant reference for the subsequent research on non-Saccharomyces and fig wines.

Wu, Bingyu et al. published their research in Yancao Keji in 2021 | CAS: 106-73-0

Methyl heptanoate (cas: 106-73-0) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: 106-73-0

Smoke transfer of aroma components in slim cigarettes flavored by different methods was written by Wu, Bingyu;Fei, Ting;Luo, Chen;Bi, Yanjiu;Ma, Lichao;Tao, Liqi;Wu, Da.

To study the influences of four flavoring methods (cut tobacco, breakable capsule, tow, and cotton thread flavoring) on the transfer of aroma components in slim cigarette smoke, a gas chromatog.-tandem mass spectrometry (GC-MS/MS) method for simultaneously and quant. determining the alcs., aldehydes, ketones and esters in cut tobacco, particulate matter of mainstream smoke, and filter were developed. The results showed that: 1) After storing airtightly for 30 days, the distribution of aroma components in cut tobacco and filter differed significantly among the cigarettes flavored by the four methods. The transfer rates of aroma components were the highest in tobacco-flavored samples. 2) The transfer rates of aroma components to particulate matter of mainstream smoke in tow-flavored samples were similar to those in thread-flavored samples. The transfer rates of aroma components with higher b.ps. were the highest in tobacco-flavored samples and the lowest in capsule-flavored samples. 3) With the increase of b.ps. of congeneric aroma components, the transfer rates of aldehydes, ketones and esters aroma components to particulate matter of mainstream smoke in tobacco-flavored, tow-flavored and thread-flavored samples increased, while those in capsule-flavored samples increased first and then decreased. The alc. aroma components slightly differed from the other aroma components in the relationships between the transfer rate to particulate matter of mainstream smoke and b.p. 4) The filter retention rates of the four kind aroma components in tow-flavored samples were slightly higher than those in thread-flavored samples. Capsule flavoring resulted in the highest filter retention rates of aroma components with higher b.ps., while tobacco flavoring was the opposite.

The liquid-liquid phase equilibrium and interfacial properties of Me ester + water binary mixtures are determined at atm. pressure and from 278 to 358 K combining the direct coexistence technique and mol. dynamics simulations. Me esters are modeled using new parametrizations based on the united atom TraPPE model force field proposed recently by us [E. Feria, J. Algaba, J. M. Miguez, A. Mejia, P. Gomez-Alvarez and F. J. Blas, Phys. Chem. Chem. Phys., 2019, 22, 4974-4983] that are able to predict the vapor-liquid interfacial properties of pure Me esters with high accuracy. In the case of water, we consider the well-known TIP4P/2005 model, the most popular rigid and non-polarizable model to describe the interfacial properties of pure water. The simulations are performed using the direct coexistence technique in the isothermal-isobaric or NPzAT ensemble in combination with mol. dynamics. We obtain d. profiles, temperature-densities and temperature-composition projections of the phase diagrams, and interfacial tensions. The liquid-liquid interfacial tension is calculated from the normal and tangential components of the pressure tensor according to the mech. virial route. We pay attention particularly to the ability of the mol. models in predicting the exptl. behavior of the systems. Simulation results are able to account for the liquid-liquid phase equilibrium of these binary mixtures, in good agreement with the exptl. data taken from the literature. Unfortunately, exptl. values for interfacial tensions are substantially overestimated by predictions from computer simulations in all cases. To our knowledge, this is the first time that the liquid-liquid phase equilibrium and interfacial properties of Me ester + water mixtures have been predicted from computer simulations.

The advancement of polymeric materials relies heavily on the innovation in polymerization reactions. In this study, we have discovered alternating copolymerization of isothiocyanate (ITC) and epoxide, which results in a nearly unexploited sulfur-containing polymer, polythioimidocarbonate (PTC). Provided with a simple two-component catalyst, i.e., a Lewis pair consisting of triethylborane (Et3B) and excess phosphazene base (PB), the copolymerization starts from an alc. and proceeds in a strictly alternating and highly chemoselective manner, yielding PTC with controlled molar mass and low dispersity, free of cyclic byproducts and ether linkages. The method applies well to a variety of ITCs and epoxides. It is also found with great excitement that the reaction on ITC is fully inhibited when the catalyst composition is inverted to have Et3B in excess, while homopolymerization of epoxide occurs selectively in this case. D. functional theory (DFT) calculation reveals that Et3B-alkoxide complexation is the key to suppressing the back-biting reaction during the copolymerization ([Et3B] < [PB]) and inhibiting the copolymerization ([Et3B] > [PB]). This unique “biased” feature is harnessed to develop a catalyst switch strategy for one-pot block copolymerization from the mixture of ITC and epoxide following either a copolymerization or homopolymerization of the first order, resulting in tailor-made PTC-polyether block copolymers with reversible sequence structures. On the other hand, sequence-selective terpolymn. occurs from a mixture of phthalic anhydride, ITC, and epoxide, allowing the one-step synthesis of polyester-PTC block terpolymer.

Objective: To investigate phytochems. and biol. activities of Capparis cartilaginea extracts Methods: The methanolic extracts of leaves, stem and twigs of C. cartilaginea were screened for their phytochems. The essential oil of the leaves was hydrodistd. by a Clevenger apparatus and analyzed by gas chromatog.-mass spectrometry (GC-MS). The leaves extract of C. cartilaginea was evaluated for its anti-inflammatory effect, using formalin-induced paw edema. The leaves, stem and twig extracts were assessed for their antioxidant activity, using free radical scavenging assay, cytotoxic activity, using 3-[4,5-dimethylthiazole-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay and antibacterial activity, using the microdilution method. Results: All extracts of C. cartilaginea contained alkaloids, carbohydrates, protein, coumarin, phytosterols, bitter principles, phenols and tannins. The essential oil of the leaves was mainly composed of iso-Pr isothiocyanate (69.4%), butane,1-isothiocyanate (26.97%) and iso-Bu isothiocyanate (3.26%). The leaves extract at doses of 200 and 400 mg/kg, significantly inhibited paw edema at the 3rd h (49.1%, 54.0%, resp.) and this effect was comparable to that of diclofenac (58.87%). The leaves extract showed the highest antioxidant activity with IC50 value of 91.71渭g/mL. The twigs extract exhibited the highest cytotoxic activity against human lung carcinoma (A549) with IC50 of 57.5渭g/mL. The leaves and stem extracts exhibited antibacterial activity against Staphylococcus aureus with min. inhibitory concentration (MIC) of 5.0 mg/mL. Conclusion: The leaves extract of C. cartilaginea is a potential source of bioactive compounds that could have a role in anti-inflammation. Twigs extract of the C. cartilaginea possesses a potential cytotoxic effect on human lung cell line.

Earth abundant, first row transition metals offer a cheap and sustainable alternative to the rare and precious metals. However, utilization of first row metals in catalysis requires harsh reaction conditions, suffers from limited activity, and fails to tolerate functional groups. Reported here is a highly efficient iron catalyzed hydroformylation of alkenes under mild conditions. This protocol operates at 10-30 bar syngas pressure below 100 掳C, utilizes readily available ligands, and applies to an array of olefins. Thus, the iron precursor [HFe(CO)4][Ph3PNPPh3]+ in the presence of tri-Ph phosphine catalyzes the hydroformylation of 1-hexene, 1-octene, 1-decene, 1-dodecene, 1-octadecene, trimethoxy(vinyl)silane, trimethyl(vinyl)silane, cardanol, 2,3-dihydrofuran, allyl malonic acid, styrene, 4-methylstyrene, 4-iBu-styrene, 4-tBu-styrene, 4-methoxy styrene, 4-acetoxy styrene, 4-bromo styrene, 4-chloro styrene, 4-vinylbenzonitrile, 4-vinylbenzoic acid, and allyl benzene to corresponding aldehydes in good to excellent yields. Both electron donating and electron withdrawing substituents could be tolerated and excellent conversions. Remarkably, the addition of 1 mol % acetic acid promotes the reaction to completion within 16-24 h. Detailed mechanistic investigations revealed in situ formation of an iron-dihydride complex [H2Fe(CO)2(PPh3)2] (A) as an active catalytic species. This finding was further supported by cyclic voltammetry investigations and intermediacy of an Fe(0)-Fe(II) species was established. Combined exptl. and computational investigations support the existence of an iron-dihydride as the catalyst resting state, which then follows a Fe(II) based catalytic cycle to produce aldehyde.

Surface coating facilities are major sources of volatile organic compounds (VOCs) in urban areas. These VOCs can contribute to ground-level ozone formation, and many are hazardous air pollutants (HAPs), including xylene, ethylbenzene, and toluene. This project was conducted in order to provide information for updating the Texas Commission on Environmental Quality TCEQ, USA, permit by rule for Surface Coating Facilities. Project objectives were: (1) to develop a database of information regarding surface coating facilities in Texas; (2) to estimate maximum emission rates for various VOC species from surface coating facilities in Texas; (3) to conduct dispersion modeling to estimate off-site impacts from surface coating facilities. The database was developed using 286 TCEQ permit files authorizing surface coating facilities in Texas during 2006 and 2007. The database was designed to include information important for estimating emission rates, and for using as inputs to the dispersion model. Hourly and annual emissions of volatile organic compounds VOCs, particulate matter PM, and exempt solvents ES were calculated for each permitted entity/ company in the database, according to equations given by TCEQ. Dispersion modeling was then conducted for 3 facility configurations worst-case stack height, good practice stack height, and fugitive emissions, for urban and rural dis- persion parameters, for 8-h and 24-h operating scenarios, and for 1-h, 24-h, and annual averaging times, for a total of 36 scenarios. The highest modeled concentrations were for the worst-case stack height, rural dispersion parameters, 24-h operation scenario, and 1-h averaging time. 108 specific chem. species, which are components of surface coatings, were identified as candidates for further health impacts review.

Five fungal species, Cladosporium resinae (ATCC 34066), Cladosporium sphaerospermum (ATCC 200384), Exophiala lecanii-corni (CBS 102400), Mucor rouxii (ATCC 44260), and Phanerochaete chrysosporium (ATCC 24725), were tested for their ability to degrade nine compounds commonly found in industrial off-gas emissions. Fungal cultures inoculated on ceramic support media were provided with volatile organic compounds (VOCs) via the vapor phase as their sole carbon and energy sources. Compounds tested included aromatic hydrocarbons (benzene, ethylbenzene, toluene, and styrene), ketones (Me Et ketone, Me iso-Bu ketone, and Me Pr ketone), and organic acids (Bu acetate, Et 3-ethoxypropionate). Experiments were conducted using three pH values ranging from 3.5 to 6.5. Fungal ability to degrade each volatile organic compound (VOC) was determined by observing the presence or absence of visible growth on the ceramic support medium during a 30-day test period. The results indicate that E. lecanii-corni and C. sphaerospermum can readily utilize each of the nine VOCs as a sole carbon and energy source. P. chrysosporium was able to degrade all VOCs tested except for styrene under the conditions imposed. C. resinae was able to degrade both organic acids, all of the ketones, and some of the aromatic compounds (ethylbenzene and toluene); however, it was not able to grow utilizing benzene or styrene under the conditions tested. With the VOCs tested, M. rouxii produced visible growth only when supplied with Bu acetate or Et 3-ethoxypropionate. Maximum growth for most fungi was observed at a pH of approx. 5.0. The exptl. protocol utilized in these studies is a useful tool for assessing the ability of different fungal species to degrade gas-phase VOCs under conditions expected in a biofilter application.

Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Formula: C4H7NS

Active ingredients and mechanisms of Phellinus linteus (grown on Rosa multiflora) for alleviation of Type 2 diabetes mellitus through network pharmacology was written by Oh, Ki Kwang;Adnan, Md.;Cho, Dong Ha. And the article was included in Gene in 2021.Formula: C4H7NS The following contents are mentioned in the article:

Phellinus linteus (mushroom) grown on Rosa multiflora (PL@RM), exposed beneficial effect and safety on Type 2 diabetes mellitus (T2DM) from Korean folk remedies. However, its active chem. constituents and mechanism(s) against T2DM have not been confirmed. Hence, we deciphered the active compounds and mechanism(s) of PL@RM against T2DM through network pharmacol. GC-MS of PL@RM manifested 54 compounds and drug-likeness properties of these compounds were confirmed by Lipinski’s rule. The compound (40) related genes were composed of Similarity Ensemble Approach (SEA) and SwissTargetPrediction (STP). The overlapping genes (61) between the two databases were identified. Besides, the T2DM related genes (4,736) were extracted from DisGeNet and OMIM database. In parallel, a Venn diagram was constructed between the overlapping genes (61) and T2DM related genes (4,736), and finally, 48 genes were picked. The interactive networks between compounds and overlapping genes were plotted and visualized by RStudio. In addition, KEGG Pathway enrichment anal. was evaluated by String. String anal. showed that the mechanisms of PL@RM against T2DM were related to 16 pathways, where inhibition of gluconeogenesis by inactivating metabolic pathways was noted as the hub pathway of PL@RM against T2DM. Besides, bubble chart indicated that activation of the AMPK signaling pathway might enhance the insulin receptor (IR) phosphorylation, which is regarded the key signaling pathway of PL@RM against T2DM. Furthermore, the autodock vina revealed the promising binding affinity energy of the epicholesterol (the most drug-likeness compound) on HMGCR (hub gene). Overall, this work hints at the therapeutic evidence of PL@RM on T2DM, and this data expound the main chem. compounds and mechanisms of PL@RM against T2DM. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Formula: C4H7NS).
