The expression profiles of acid-stable alpha-amylase and acid-labile alpha-amylase of Aspergillus luchuensis mut. Kawachii effect on the microstructure of koji and alcohol fermentation

We investigated the contribution of the complex expressions of two alpha-amylases, namely acid-stable alpha-amylase (AS-amylase) and acid-labile alpha-amylase (AL-amylase), from Aspergillus kawachii to the microstructure of koji and the brewing. AL-amylase was found to be the primary contributor to the decomposition of starch in the early stage of koji making. From the middle stage, both alpha-amylases decomposed the starch in a coordinated manner, and at the final stage, acid-stable alpha-amylase and glucoamylase decomposed the starch granules. Characterization of koji prepared by the single disruptions of AS-amylase or AL-amylase genes, double disruption of both alpha-amylase genes, and triple disruption of two alpha-amylase and glucoamylase genes in A. kawachii cells indicated that both alpha-amylases can work in a synergistic manner to decompose starches during koji making. AL-amylase was found, for the first time, to play an important role in starch decomposition in koji. The speed of alcohol fermentation and ester contents of the fermented mash were higher the mash prepared the control strain, followed by single, double, and triple disruptants. These results indicate that the microstructure of koji plays a role in promoting alcohol fermentation and flavor development.

Alkylation of a hydrophilic photosensitizer enhances the contact-dependent photo-induced oxidation of phospholipid membranes

Lipophilic photosensitizers able to photo-induce lipid oxidation in biomembranes are, in general, much more efficient than hydrophilic ones; acting through the formation of singlet oxygen (O-1(2)), which oxidizes the fatty acid double bonds (type II mechanism). Here we investigate the binding and photosensitizing properties of 4-(decyloxy)pteridin-2-amine (O-decyl-Ptr) using unilamellar vesicles of 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC), a phospholipid with monounsaturated fatty acids. By means of molecular dynamic (MD) simulations, we showed that O-decyl-Ptr binds to the membrane in a localization that favors the direct reaction of the triplet excited state of O-decyl-Ptr with DOPC double bonds. As a consequence, although O-1(2) is formed, O-decyl-Ptr acts mainly as a contact-dependent photosensitizer, meaning through radical formation (type I mechanism). Mass spectrometry analysis of vesicles irradiated in the presence of O-decyl-Ptr, demonstrated the generation of alcohols (LOH), ketones (LO) and hydroperoxides (LOOH). In agreement with the mechanistic hypothesis proposed, LOH and LO (type I photooxidation products) are formed faster than LOOH (type II photooxidation product). Interestingly, no short-chain oxidized products were detected. Accordingly, membrane fluctuations and formation of filaments and buds are observed during in-situ photo-activation of O-decyl-Ptr in giant unilamellar vesicles due to changes in membrane spontaneous curvature. Finally, we evaluated the effect of the photochemical processes studied at a cellular level and demonstrated in experiments of viability of mammalian cells that O-decyl-Ptr has important photodynamic properties. Similar experiments performed using the hydrophilic photosenstizer pterin (Ptr) show that alkylation leads to a striking increase in the efficiency of photosensitized lipid oxidation.

Cellulose nanofibrils-based hybrid foam generated from Pickering emulsion toward high-performance microwave absorption

The development of multifunctional microwave absorbers that worked in complex environments remains challenging. In this study, oil-in-water Pickering emulsion gelation approach was combined with freeze-drying to prepare foam-based microwave absorbers along with appealing photo-thermal conversion and thermal insulation. In hybrid foam, cellulose nanofibrils (CNP) and polylactic acid (PLA) serve as three-dimensional skeleton, where carbon nanotubes (CNT) and Fe3O4 nanoparticles are homogeneously incorporated, which forms a conductive network with hetero-interfaces. The optimal reflection loss value of the foam reaches -65.14 dB with a thickness of 3.0 mm. The foam also demonstrate high photo-thermal conversion performance with its surface temperature up to 97 degrees C after irradiation under 1 Sun for 5 min. Additionally, the foam shows superior thermal insulation comparing with the commercial polyvinyl alcohol and polyurethane foams. This study may offer a promising approach to develop ultralight and high-performance microwave absorber with great potential for multifunctional applications.

Interest of black carob extract for the development of active biopolymer films for cheese preservation

The aim of this work was to develop bio-based packaging materials based on black carob extracts (BCE) and kappa-carrageenan (kappa-c) blends, and to study their impact for cheese preservation. Firstly, black carob extracts were obtained with and without alcohol pre-treatment (BCE-a and BCE-b), respectively, and its chemical composition and antioxidant properties was analysed. Protein and polyphenol contents were higher in the extract without alcohol pre-treatment (BCE-b). Different bio-based films were prepared by mixing BCEs with kappa-c at different ratios, and the morphological, thermal, mechanical and water barrier properties of the films were evaluated. The antioxidant efficacy of BCE:kappa-c films prepared with both BCE extracts was further compared when applied on the preservation of cheese slides. Results showed that skipping the ethanolic extraction pre-treatment gave rise to more ductile films due to the presence of sucrose and other small sugars or the higher protein content in the BCE-b extract, which could have a plasticizer effect on the biopolymer network. Mixtures with kappa-c increased the rigidity of the films. A good correlation between barrier properties of films and the antioxidant efficacy on cheese samples was observed, suggesting that not only the antioxidant properties but also the physicochemical properties of the films had a direct impact on cheese quality and preservation. Films prepared with both BCEs at 50:50 BCE:kappa-c ratio and those prepared with BCE-a at 25:75 BCE:kappa-c ratio, presented good antioxidant capacity and a good compromise for physicochemical properties. However, from the economical point of view, 50:50 BCE-b:kappa-c films are more suitable since the extraction protocol of BCE-b was simpler and the yield was three-fold higher.

TiO2 and TiO2/Ag nanofibers: template synthesis, structure, and photocatalytic properties

A fairly simple method for the synthesis of TiO2 and TiO2/Ag fibers containing the anatase-rutile-silver heterojunction with a combination of features attractive for photocatalysis is presented.TiO2 and TiO2/Ag fibers were synthesized by impregnating a cellulose template with alcohol solutions of titanium(IV) tetrabutoxide and silver nitrate, followed by annealing at 500-950 degrees C. The microstructure of the fibers was analyzed by X-ray diffraction, scanning electronic microscopy, high-resolution transmission electronic microscopy and IR Fourier spectroscopy. The thermal decomposition of silver nitrate results in the formation of silver particles (19 +/- 3 nm), does not affect the crystallite size of anatase (19 +/- 3 nm) and rutile (23 +/- 3 nm), and promotes rutilization of TiO2. The photocatalytic activities of the obtained TiO2/Ag fibers were investigated by evaluating the phenol degradation under visible light irradiation. The highest catalytic activity was shown by mixed-phase samples consisting of 40% rutile and 60% anatase.

Hydrogen-Bonding Assisted Catalytic Kinetic Resolution of Acyclic beta-Hydroxy Amides

Enantioenriched acyclic alpha-substituted beta-hydroxy amides are valuable compounds in chemical, material and medicinal sciences, but their enantioselective synthesis remains challenging. A catalytic kinetic resolution (KR) of such amides with selectivity factor(s) up to >200 is developed via enantioselective acylation of primary alcohol with N-heterocyclic carbene. An enhanced selectivity for the catalytic KR process is realized using cyclic tertiary amine as base additive. Diastereomeric transition state models for the process are proposed to rationalize the origin of enantioselectivity.

General procedure: Synthesis of [CmOHMIM][HOCnSO3]) and [CmOHTEA][HOCnSO3]: ILs were prepared by ion exchange method. The ion exchange of the anion chloride by the anion hydroxyalkanesulphonate was carried out using an exchange column packed with 100 g of Amberlite IR120 H-type strongly acidic cation exchange resin. The column was previously flushed thoroughly with a 1 mol L- 1 [CmOHMIM]Cl or [CmOHTEA]Cl solution until the elution was neutral, then with Milli-Q water until no chloride was detected by silver nitrate. A 100 mL of 1 mol L- 1 Na[HOCnSO3] solution was slowly run over and eluted with Milli-Q water. The eluted liquid was collected and concentrated under reduced pressure in a rotary evaporator. The residue was then vacuum dried at 323 K for 18 h to afford the IL in near-quantitative yield as a colorless viscous liquid. ILs with ions containing hydroxyl groups are usually observed to be rather viscous. 1-(2-Hydroxyethyl)-3-methyl-imidazolium hydroxymethane sulfonate ([C2OHMIM][HOC1SO3]) 1H NMR (400 MHz, D2O, 298 K): 3.89 (s, 3H), 3.91 (t, J = 5.0 Hz, 2H), 4.30 (t, J = 4.83 Hz, 2H), 4.35 (s, 2H), 7.44 (s, 1H), 7.50 (s, 1H), 8.72 (s, 1H); 13C NMR (400 MHz, D2O, 298 K): 35.29, 51.08, 59.35, 73.71, 122.01, 123.18, 135.92.
