Influence of Patagonian Lactiplantibacillus plantarum and Oenococcus oeni strains on sensory perception of Pinot Noir wine after malolactic fermentation

Background and Aims The aim of this work was to study the effect of two Patagonian malolactic starters, Oenococcus oeni UNQOe 73.2 and Lactiplantibacillus plantarum UNQLp 11, on the wine composition and sensory perception after MLF of Pinot Noir wine. Methods and Results Both strains increased the concentration of procyanidin, diminished the concentration of phenolic substances and increased the colour intensity of the wine after MLF. The volatile profile of both strains differed to that of the Control, particularly the esters, vanillin and some terpenes. The attributes acidity and astringency, black and dried fruits and spicy attributes were features of the wine fermented with both strains. Conclusions Both strains were able to conduct MLF, to increase colour intensity and to change the flavour of the wine with some differences. The wine fermented with UNQLp 11 had a greater frequency of bitterness, whereas the wine fermented with UNQOe 73.2 had a greater frequency of butter. Significance of the Study Knowledge of the effect of Patagonian starter cultures on consumer perception of the wine after fermentation has been improved.

A Mini Review on the Cold Flow Properties of Biodiesel and its Blends

Biodiesels are renewable fuel that may be produced from various feedstock using different techniques. It is endorsed in some countries of the world as a viable substitute to diesel fuel. While biodiesel possesses numerous benefits, the cold flow properties (CFP) of biodiesel in comparison with petro-diesel are significantly less satisfactory. This is due to the presence of saturated and unsaturated fatty acid esters. The poor CFP of biodiesel subsequently affects performance in cold weather and damages the engine fuel system, as well as chokes the fuel filter, fuel inlet lines, and injector nozzle. Previously, attempts were made to minimize the damaging impact of bad cold flow through the reduction of pour point, cloud point, and the cold filter plugging point of biodiesel. This study is focused on the biodiesel CFP-related mechanisms and highlights the factors that initialize and pace the crystallization process. This review indicates that the CFP of biodiesel fuel can be improved by utilizing different techniques. Winterisation of some biodiesel has been shown to improve CFP significantly. Additives such as polymethyl acrylate improved CFP by 3-9 degrees C. However, it is recommended that improvement methods in terms of fuel properties and efficiency should be carefully studied and tested before being implemented in industrial applications as this might impact biodiesel yield, cetane number, etc.

Response surface methodology for optimization of Rhizopus stolonifer 1aNRC11 mutant F whole-cell lipase production as a biocatalyst for methanolysis of waste frying oil

Biodiesel, fatty acid methyl ester (FAME), is an environmentally friendly alternative fuel produced by transesterification of renewable lipid feedstocks for diesel engines. Methanolysis of waste frying oil (WFO) was catalyzed by Rhizopus stolonifer 1aNRC11 mutant F whole-cell lipase that produced under solid state fermentation (SSF) using wheat bran (WB) and black cumin meal as the main substrate. Cultivation SSF parameters of R. stolonifer mutant were optimized using Plackett-Burman (PB) experimental design and Face-centred Central Composite Design (FCCD), taking FAME yield as a response for whole-cell lipase production ability. PB results showed that cultivation temperature, medium pH and moisture content were the most significant parameters, which were selected for optimization by FCCD. The optimal determined conditions were as follows: WB (10 g), black cumin meal (6%, w/w of WB), fodder yeast (1%, w/w of WB), moisture content (1.5 g water/g solid), inoculum size (3 discs), initial pH (8), and cultivation time (4 day) at 28 degrees C. With R. stolonifer mutant cultivated in the optimized conditions, the FAME yield reached 82.6% that was close to the predicted yield of 85.7%. The analysis of variance showed that the model was statistically significant (p value of .0001) and could explain 89% of the variability in the response. These results indicated that the optimization conditions increased biodiesel production by about 43% compared to the basal medium (57.60%). The optimization of SSF conditions using low cost components makes the whole-cell lipase production process from the R. stolonifer 1aNRC11 mutant F economically effective for application in biodiesel production from WFO.

High-performance near-infrared organic phototransistors based on diketopyrrolopyrrole conjugated polymers with partial removal of long branched alkyl side chains

Near-infrared (NIR) organic phototransistors (OPTs) based on diketopyrrolopyrrole (DPP) conjugated polymers with partially removed long branched alkyl side chains are reported with significantly improved NIR photoresponses, which take advantage of both strengthened NIR absorption and improved charge transport. The NIR OPTs based on the terpolymer with properly partial removal of the alkyl side chains showed much higher photoresponsivity R (567 A W-1) and larger photosensitivity P (similar to 10(6)) as compared to those of the other two control devices based on DPP conjugated polymers without removal or with excessive removal of the alkyl side chains. By incorporating a small amount of [6,6]phenyl-C61-butyric acid methyl ester into the terpolymers with partially removed side chains, the resulting NIR OPTs exhibited ultralow detection limit (0.002 mW cm(-2)) and presented very high sensitivity with a maximum R of 4234 A W-1 and specific photodetectivity D* of 5.6 x 10(13) Jones. These findings demonstrated that side chain engineering in conjugated polymers provides an excellent opportunity for developing high performance organic photodetectors.

FMPhos: Expanding the Catalytic Capacity of Small-Bite-Angle Bisphosphine Ligands in Regioselective Alkene Hydrofunctionalizations

In contrast to the plethora of large-bite-angle bisphosphine ligands available to transition-metal catalysis, the development of small-bite-angle bisphosphine ligands has suffered from the limited structural variations accessible on their single-atom-containing backbones. Herein, we report the design and applications of a discrete very small bite-angle bisphosphine ligand, namely, FMPhos. Featuring a fluorene-methylene unit appended on the single-carbon linker, the ligand harbors an unusually rigid backbone that presumably stabilizes its complexation with transition metals during catalysis. Compared with the known dppm ligand, it exhibited superior reactivity and regioselectivity in a number of alkene hydrofunctionalization reactions, catalyzed by iridium and rhodium.

Omega-3 polyunsaturated fatty acids focusing on eicosapentaenoic acid and docosahexaenoic acid in the prevention of cardiovascular diseases: a review of the state-of-the-art

Introduction: An epidemiological study of Greenlandic Inuit suggested the importance of omega-3 polyunsaturated fatty acids (PUFAs) in preventing ischemic heart disease. After this landmark study, large-scale epidemiological studies have examined the benefits of omega-3 PUFAs in the prevention of cardiovascular diseases. Areas covered: This article reviews studies on omega-3 PUFAs, and identifies issues relevant to cardiovascular risk. Expert opinion: Recent studies have focused on the anti-inflammatory effects of omega-3 PUFAs and specialized pro-resolving mediators. High-purity eicosapentaenoic acid (EPA) ethyl ester and EPA/docosahexaenoic acid (DHA) preparations have been developed primarily for the treatment of hypertriglyceridemia. Various trials on the cardiovascular protective effects of omega-3 PUFAs have been reported, but the results have not been consistent. Some issues of the trials have been suggested, such as using low-dose omega-3 PUFAs and not including hypertriglyceridemia in subject selection criteria. REDUCE-IT study that used a high dose of high-purity EPA preparation showed a relative reduction in cardiovascular events, but, the STRENGTH study that used a high dose of EPA/DHA preparation did not support this benefit. This article reviews the roles of omega-3 PUFAs in cardiovascular diseases, including progress in understanding the molecular mechanisms and recent large-scale clinical trials.

Route evaluation and development of a practical synthesis of methyl (S)-2-chloro-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine-7-carboxylate

A rapid and reliable route to methyl (S)-2-chloro-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine-7-carboxylate moiety that is useful as a synthetic scaffold is described. Previously, this Boc-protected entity was prepared in 10 chemical steps starting with L-hydroxyproline with an overall yield of 0.67%. The newly developed synthetic route provided the desired target in seven chemical steps with an overall yield up to 38%. Three main issues that needed to be addressed with the previous route were; first, the ring expansion of the L-hydroxyproline that generated an inseparable regioisomeric mixture (1.5:1) by flash chromatography; secondly, the low yielding condensation step between the keto ester and urea; thirdly, the low yielding chlorination of the desired isomer. Starting with commercially available (2-chloropyrimidin-5-yl)methanol, the new route incorporates a Knochel iodination, a Negishi cross-coupling, and a ring closure as the key steps. This new route afforded us the opportunity to deliver enantiomerically pure intermediate in support of drug discovery efforts. (C) 2020 Elsevier Ltd. All rights reserved.

A Novel Therapeutic Approach for Colorectal Cancer Stem Cells: Blocking the PI3K/Akt Signaling Axis With Caffeic Acid

Cancer stem cells (CSCs) have been identified in a multiple of cancer types and resistant to traditional cancer therapies such as chemotherapeutic agents and radiotherapy, which may destroy bulk tumor cells but not all CSCs, contributing to reformation tumor masses and subsequent relapse. Moreover, it is very difficult to effectively identify and eliminate CSCs because they share some common phenotypic and functional characteristics of normal stem cells. Therefore, finding better therapeutic strategies to selectively target CSCs might be helpful to reduce subsequent malignancies. In the present study, we found that caffeic acid effectively suppresses self-renewal capacity, stem-like characteristics, and migratory capacity of CD44(+) and CD133(+) colorectal CSCs in vitro and in vivo. In addition, we also revealed that PI3K/Akt signaling may be linked to multiple colorectal CSC-associated characteristics, such as radio-resistance, stem-like property, and tumorigenic potential. To the best of our knowledge, this is the first study demonstrating that caffeic acid effectively targets colorectal CSC populations by inhibiting the growth and/or self-renewal capacity of colorectal CSCs through PI3K/Akt signaling in vitro and in vivo.
