Roggatz, Christina C. published the artcileModelling Antifouling compounds of Macroalgal Holobionts in Current and Future pH Conditions, Recommanded Product: 17-Hydroxyheptadecanoic acid, the main research area is pH ocean acidification antifouling compound Rhodophyta Chlorophyta; Macroalgae; and macro-colonizers; antifouling; chemical communication; climate change; micro; ocean acidification.

Marine macroalgae are important ecosystem engineers in marine coastal habitats. Macroalgae can be neg. impacted through excessive colonization by harmful bacteria, fungi, microalgae, and macro-colonisers and thus employ a range of chem. compounds to minimize such colonization. Recent research suggests that environmental pH conditions potentially impact the functionality of such chem. compounds Here we predict if and how naturally fluctuating pH conditions and future conditions caused by ocean acidification will affect macroalgal (antifouling) compounds and thereby potentially alter the chem. defense mediated by these compounds We defined the relevant ecol. pH range, analyzed and scored the pH-sensitivity of compounds with antifouling functions based on their modelled chem. properties before assessing their distribution across the phylogenetic macroalgal groups, and the proportion of sensitive compounds for each investigated function. For some key compounds, we also predicted in detail how the associated ecol. function may develop across the pH range. The majority of compounds were unaffected by pH, but compounds containing phenolic and amine groups were found to be particularly sensitive to pH. Future pH changes due to predicted average open ocean acidification pH were found to have little effect. Compounds from Rhodophyta were mainly pH-stable. However, key algal species amongst Phaeophyceae and Chlorophyta were found to rely on highly pH-sensitive compounds for their chem. defense against harmful bacteria, microalgae, fungi, and biofouling by macro-organisms. All quorum sensing disruptive compounds were found the be unaffected by pH, but the other ecol. functions were all conveyed in part by pH-sensitive compounds For some ecol. keystone species, all of their compounds mediating defense functions were found to be pH-sensitive based on our calculations, which may not only affect the health and fitness of the host alga resulting in host breakdown but also alter the associated ecol. interactions of the macroalgal holobiont with micro and macrocolonisers, eventually causing ecosystem restructuring and the functions (e.g. habitat provision) provided by macroalgal hosts. Our study investigates a question of fundamental importance because environments with fluctuating or changing pH are common and apply not only to coastal marine habitats and estuaries but also to freshwater environments or terrestrial systems that are subject to acid rain. Hence, while warranting exptl. validation, this investigation with macroalgae as model organisms can serve as a basis for future investigations in other aquatic or even terrestrial systems.

Pereira, Filipa’s team published research in Molecular Systems Biology in 2021-07-31 | CAS: 97-67-6

Pereira, Filipa published the artcileModel-guided development of an evolutionarily stable yeast chassis, Quality Control of 97-67-6, the main research area is transcriptome proteome metabolome succinate fumarate malate dehydrogenase Saccharomyces; adaptive laboratory evolution; chassis cell; metabolic engineering; multi-objective optimization; systems biology.

First-principle metabolic modeling holds potential for designing microbial chassis that are resilient against phenotype reversal due to adaptive mutations. Yet, the theory of model-based chassis design has rarely been put to rigorous exptl. test. Here, we report the development of Saccharomyces cerevisiae chassis strains for dicarboxylic acid production using genome-scale metabolic modeling. The chassis strains, albeit geared for higher flux towards succinate, fumarate and malate, do not appreciably secrete these metabolites. As predicted by the model, introducing product-specific TCA cycle disruptions resulted in the secretion of the corresponding acid. Adaptive laboratory evolution further improved production of succinate and fumarate, demonstrating the evolutionary robustness of the engineered cells. In the case of malate, multi-omics anal. revealed a flux bypass at peroxisomal malate dehydrogenase that was missing in the yeast metabolic model. In all three cases, flux balance anal. integrating transcriptomics, proteomics and metabolomics data confirmed the flux re-routing predicted by the model. Taken together, our modeling and exptl. results have implications for the computer-aided design of microbial cell factories.

Uda, Ryoko M.’s team published research in Materials Letters in 2021-11-15 | CAS: 7575-23-7

Materials Letters published new progress about Leuco dyes. 7575-23-7 belongs to class alcohols-buliding-blocks, name is Pentaerythritol tetra(3-mercaptopropionate), and the molecular formula is C17H28O8S4, Recommanded Product: Pentaerythritol tetra(3-mercaptopropionate).

Uda, Ryoko M. published the artcileMalachite green leuco derivatives as photobase generators for initiating crosslinking and polymerization, Recommanded Product: Pentaerythritol tetra(3-mercaptopropionate), the main research area is malachite green derivative photobase generator crosslinking anionic photopolymerization initiator.

We investigated the pH-changing profile induced by UV irradiation of malachite green leuco derivatives (MG-Xs) and performed polymerization and crosslinking reactions initiated by irradiated MG-Xs. A substituent (X) is covalently linked to the central carbon atom of malachite green, abbreviated as MG-OH or MG-OCH3. MG-Xs undergo photoionization to afford malachite green cations and anions (X-), which act as photobase generators. We found that MG-OCH3 was as effective as MG-OH for photoionization and photo-induced pH jumping. Anionic photo-polymerization of Me methacrylate was accomplished via irradiation of MG-Xs. Irradiation of MG-Xs triggered the base-promoted crosslinking reaction between pentaerythritol tetra(3-mercaptopropionate) and hexamethylene diisocyanate.

Han, Di published the artcileEngineering the Surface Pattern of Microparticles: From Raspberry-like to Golf Ball-like, Synthetic Route of 7575-23-7, the main research area is microparticle surface structure shape silsesquioxane; golf ball-like; microparticles; polyhedral oligomeric silsesquioxane; raspberry-like; thiol−epoxy polymerization.

Control of the shape and uniformity of colloid particles is essential for realizing their functionality in various applications. Herein, we report a facile approach for the synthesis of narrowly dispersed anisotropic microparticles with well-defined raspberry-like and golf ball-like surface patterns. First, we demonstrate that hybrid raspberry-like particles can be achieved through a one-pot polymerization method using glycidyl polyhedral oligomeric silsesquioxane (GPOSS) and pentaerythritol tetra(3-mercaptopropionate) (PETMP) as monomers. Varying the polymerization parameters such as catalyst loading, monomer concentration, and the molar ratio of monomers, we are able to regulate the sizes and surface protrusion numbers of these raspberry-like microparticles. The formation mechanism is attributed to a competition balance between thiol-epoxy reaction and thiol-thiol coupling reaction. The former promotes rapid formation of large core particles between PETMP and GPOSS droplets (which can serve as core particles), while the latter allows for generation of surface protrusions by PETMP self-polymerization, leading to the formation of raspberry-like surface patterns. Based on the different POSS contents in the surface protrusions and cores of the raspberry-like microparticles, we demonstrate that they can be used as precursors to produce microporous silica (sub)microparticles with golf ball-like morphol. via pyrolysis subsequently. Overall, this work provides a facile yet controllable approach to synthesize narrowly dispersed anisotropic microparticles with diverse surface patterns.

Journal of Agricultural and Food Chemistry published new progress about Food aging. 505-10-2 belongs to class alcohols-buliding-blocks, name is 3-(Methylthio)propan-1-ol, and the molecular formula is C4H10OS, Category: alcohols-buliding-blocks.

Zhang, Xinyi published the artcileChanges in Red Wine Composition during Bottle Aging: Impacts of Grape Variety, Vineyard Location, Maturity, and Oxygen Availability during Aging, Category: alcohols-buliding-blocks, the main research area is grape maturity vineyard oxygen red wine bottle aging; grape maturity; grape variety; oxygen availability; red wine composition evolution; vineyard location.

This work investigated the influence of grape variety, vineyard location, and grape harvest maturity, combined with different oxygen availability treatments, on red wine composition during bottle aging. Chemometric anal. of wine compositional data (i.e., wine color parameters, SO2, metals, and volatile compounds) demonstrated that the wine samples could be differentiated according to the different viticultural or bottle-aging factors. Grape variety, vineyard location, and grape maturity showed greater influence on wine composition than bottle-aging conditions. For most measured wine compositional variables, the evolution patterns adopted from the viticultural factors were not altered by oxygen availability treatment. However, contrasting evolution patterns for some variables were observed according to specific viticultural factors, with examples including di-Me sulfide, phenylacetaldehyde, maltol, and β-damascenone for vineyard locations, 2-methylbutanal, 1,4-cineole, and linalool for grape variety, and methanethiol, methional, and homofuraneol for grape maturity.

Grundl, Gabriel published the artcileSalting-out and salting-in effects of organic compounds and applications of the salting-out effect of Pentasodium phytate in different extraction processes, HPLC of Formula: 64519-82-0, the main research area is pentasodium phytate extraction process.

The influence of different uncharged and charged organic compounds on the Lowest Solution Temperature (LST) of a water/dipropylene glycol Pr ether (DPnP) mixture is investigated. Depending on the nature of the additive, a salting-out or salting-in behavior could be observed For the binary mixture, a salting-out effect is associated with a decrease of the LST with increasing additive concentrations The reverse effects are observed with increasing salting-in additive concentrations Typical sugars, short carboxylate sodium salts, ammonium organic salts and amino-acids were found to be salting-out, whereas all studied sweeteners and organic acids showed a salting-in behavior. The Pentasodium phytate ((Phy5 -, 5Na+)) was found being the most efficient organic salting-out compound Three possible applications were investigated in order to compare the salting-out effect of (Phy5 -, 5Na+) to classical inorganic salts. First, the liquid-liquid extraction of 5-hydroxymethylfurfural (HMF) was investigated and compared to former results obtained using lithium, sodium and aluminum sulfate salts. Secondly, we considered a liquid-liquid, ethanol-water separation and compared the results to the one obtained using ammonium sulfate and potassium pyrophosphate. Finally, the salting-out effect of (Phy5 -, 5Na+) on glycerol was investigated and also compared to the inorganic salts, sodium chloride and lithium sulfate as well as potassium and sodium phosphates. Due to higher water solubility, (Phy5 -, 5Na+) allowed a more pronounced separation of HMF than the tested sulfate salts. This high water solubility drives also to a more pronounced separation of ethanol in comparison to ammonium sulfate; potassium pyrophosphate being the most water soluble and most efficient salt to sep. ethanol and water. The use of (Phy5 -, 5Na+) and potassium pyrophosphate showed a salting-out effect on glycerol in contrast to the inorganic salts sodium chloride and lithium sulfate for which a salting-in effect on glycerol was observed The salting-out effect of sodium triphosphate was limited by its water solubility

Kloetzer, Lenuta’s team published research in Separation and Purification Technology in 2019-11-15 | CAS: 111-87-5

Separation and Purification Technology published new progress about Extraction. 111-87-5 belongs to class alcohols-buliding-blocks, name is n-Octanol, and the molecular formula is C8H18O, Formula: C8H18O.

Kloetzer, Lenuta published the artcileSeparation of fumaric acid by amine extraction without and with 1-octanol as phase modifier, Formula: C8H18O, the main research area is fumaric acid reactive extraction Amberlite LA2 amine octanol modifier.

The aim of the current experiments was to study the reactive extraction of fumaric acid using Amberlite LA-2 and to comparatively analyze the influences of the process parameters (pH-value of aqueous phase, extractant concentration, and organic phase polarity) on the separation performances for the extraction systems with and without 1-octanol. Also, original equations describing the influence of extractant concentration on distribution coefficient were proposed. The results indicated that the mechanism of the interfacial reaction between acid FA(COOH)2 and extractant (Q) is controlled by the organic phase polarity and the pH-value of aqueous phase plays an important role on extraction efficiency. Thus, the structure of the extracted complexes, in the absence of 1-octanol, are FA(COOH)2Q2 for n-heptane and FA(COOH)2Q for dichloromethane. The addition of 1-octanol modified only the structure of complexes extracted in n-heptane to FA(COOH)2Q. The pos. effect of 1-octanol on extraction efficiency was quantified by means of the amplification factor, its maximum values being 2.8 for dichloromethane, and 2.48 for n-heptane. The extraction mechanism influences also the value of the extraction constant, the highest value, KE = 1.31 ·103 (L2·mol-2), was obtained for lower polarity of the organic phase, namely n-heptane.

Uslu, Hasan’s team published research in Journal of Chemical & Engineering Data in 2019-10-10 | CAS: 111-87-5

Journal of Chemical & Engineering Data published new progress about Extraction. 111-87-5 belongs to class alcohols-buliding-blocks, name is n-Octanol, and the molecular formula is C8H18O, Recommanded Product: n-Octanol.

Uslu, Hasan published the artcileExtraction of Propionic Acid from Aqueous Solutions Using Tri-n-octylphosphine Oxide and Dioctylamine in Different Solvents, Recommanded Product: n-Octanol, the main research area is propionic acid extraction TOPO dioctylamine mixture solvent.

This work examines the reactive extraction of propionic acid, a promising liquid-liquid extraction technique, using tri-n-octylphosphine oxide (TOPO) or dioctylamine (DOA) diluted with eight different solvents (n-octane, Me iso-Bu ketone (MIBK), 1-octanol, Et Me ketone, diisobutyl ketone, n-decane, di-Et sabecate, 1-decanol) at 298.15 K to determine the most efficient mixture for the extraction processes. A phosphorous-based extractant, TOPO, has been chosen for the extraction tests since it has low water solvency and is more ecol. agreeable than the amine-type extractants. Among the other amine extractants reported in reactive extraction studies, there is no study on propionic acid extraction using DOA in the literature. Phys. extraction experiments with pure solvents were also performed to analyze the effect of TOPO and DOA on the extraction process. Distribution coefficients, loading factors, and extraction yields of the processes were determined for the explanation of the results. It was concluded that the addition of TOPO or DOA to the organic phase significantly improves the extraction of propionic acid from its aqueous media. The extraction of propionic acid, using the binary solutions of TOPO/diluent or DOA/diluent, improves with an increase in the initial TOPO or DOA concentration The highest extraction yield, E% = 98.01, was achieved with the DOA + Me iso-Bu ketone (MIBK) extractant system (1.652 mol kg-1), with a distribution coefficient of KD= 49.352; thus, the use of the DOA/methyl iso-Bu ketone system in the organic phase is suggested for the propionic acid extraction methods.

A downstream process for the purification and concentration of formic acid (FA) from FA/gluconic acid (GA) mixtures, obtainable by a coupled biocatalytic reaction of CO2 reduction and glucose oxidation, has been developed. The process involved two technologies: (i) a first nanofiltration (NF) step to sep. FA and GA, and (ii) a second reactive liquid-liquid extraction (RLLE) step to concentrate FA. The NF process, using a Synder NFX membrane, consisted of three NF steps separated into two divergent lines, named permeate and retentate pathways. The first NF was common for both pathways, resulting in a permeate strongly enriched in FA and depleted in GA, and a retentate with opposite characteristics. In the permeate pathway, this first permeate was subjected to a second NF to obtain a 99.6% pure FA permeate. In the retentate pathway, an addnl. NF step on the first retentate resulted in a concentrated 99.4% pure GA retentate. The final diluted FA permeate was concentrated by RLLE using tri-N-octylamine as extractant in n-octanol, and a final back-extraction with NaOH. The optimized RLLE process involved a 100-fold volume decrease and resulted in a final FA solution (as sodium formate) of 174.5 g/L, 78 times more concentrated than the feed.

Two glycolamide based functionalized ionic liquids (ILs) having imidazolium cations namely LI (mono-ionic) and LII (di-ionic) were synthesized for the extraction of Pb(II) and Co(II) from waste water. The synthesized ligands were characterized by FTIR and NMR spectroscopy. The extraction efficiency of both mono- and di-ionic liquids was evaluated in terms of contact time, pH of the aqueous phase and metal ion concentration The metal extraction was carried out at various pH values viz. 2, 4, 6, 8, and 10 whereas, at contact time of 15, 30, 45, 60, and 75 min. The optimized pH of 4 and equilibration time of 75 min was further utilized for extraction at various metal ions concentration (50, 100, 150, 200, and 250 ppm). LI exhibited low equilibration time as compared to LII whereas, both ligands showed maximum extraction at a pH of 4. A very high extraction efficiency of up to 99% for both metals was observed with LI and LII under optimized conditions. In addition to that effective separation of Co(II) and Pb(II) was observed at pH 10.
