Boscaino, Floriana published the artcileImpact of Saccharomyces cerevisiae and Metschnikowia fructicola autochthonous mixed starter on Aglianico wine volatile compounds, COA of Formula: C4H10OS, the main research area is Saccharomyces Metschnikowia Aglianico wine volatile; Aglianico wine; Metschnikowia fructicola; S. cerevisiae; Volatile compounds.

Non-Saccharomyces yeasts are metabolically active during grape must fermentations and can contribute with enzymes and metabolites to enhance the complexity and to define the final wine aroma. Nowadays, the use of non-Saccharomyces yeasts in combination with Saccharomyces cerevisiae is a state-of-the art strategy to improve wine composition and/or wine sensory properties. The present paper deals with the new yeast strains of Metschnikowia fructicola and S. cerevisiae, that were selected as representatives of the yeast microbiota isolated from grapes and grape juice of Aglianico cultivar. S. cerevisiae was utilized both as single strain starter and in combination with M. fructicola in exptl. fermentations of Aglianico must. The dynamic of yeast populations was evaluated during the fermentation process analyzing the wine volatile compounds profile. The volatile compounds were identified by SPME-GC/MS. The results, showed that the multiple indigenous yeast starter was able to modulate the volatile compounds profiles and improve the aromatic complexity of wine, with a higher content of esters and terpenes.

King, Ellena S. published the artcileDefining the Sensory Profiles of Raw Almond (Prunus dulcis) Varieties and the Contribution of Key Chemical Compounds and Physical Properties, Related Products of alcohols-buliding-blocks, the main research area is almond chem compound sensory; almond; amygdalin; analytical; benzaldehyde; flavor; moisture; sweet; texture; volatile.

This study describes the sensory composition of com. sweet almond varieties across two California growing seasons. It also discusses the relationship between sensory attributes and chem. and phys. measures. Raw, whole almonds (43 samples each of 13 varieties in 2015 and 40 samples each of 10 varieties in 2016) were evaluated for their sensory profiles using descriptive sensory anal. The 2016 samples were also analyzed for macro- and micronutrients, amygdalin, volatile composition (using gas chromatog.-mass spectrometry), and phys. properties, and the results were modeled with the sensory data. Independence, Sonora, and Wood Colony were harder, more fracturable, and crunchy, whereas Fritz and Monterey were more moist and chewy, reflecting their moisture contents. Aldrich and Fritz were higher in marzipan/benzaldehyde flavor, which is related to amygdalin, benzaldehyde, phenylethyl alc., and benzyl alc. New insights are provided into sweet-almond composition and the sensorial contribution of headspace volatiles. This assists almond growers and processors in describing and marketing almond varieties.

Kurata, Yu published the artcileThe role of hypoxia in the pathogenesis of lupus nephritis, Product Details of C4H6O5, the main research area is HIF1 oxygen tension hypoxia lupus nephritis; hypoxia; hypoxia-inducible factor; systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is asystemic autoimmune disease of multi-factorial etiol. T cells play an important role in the pathogenesis of SLE by amplifying inflammatory responses and helping B cells to produce autoantibodies. Naive T cells are activated by recognition of an antigen signal and initiate immune responses including differentiation, expansion, and effector functions. Activated T cells shift their metabolic program toward glycolysis to generate energy and biosynthetic precursors. Hypoxia-inducible factor 1 (HIF-1), a transcription factor, plays a key role in the metabolic reprogramming of immune cells. HIF-1 regulates cellular adaptation to hypoxia and upregulates an array of target genes. In order to accommodate to hypoxic conditions, where mitochondrial oxidative phosphorylation is disrupted, HIF-1 upregulate genes related to glucose uptake and glycolysis. Proinflammatory CD4-T helper type17 (TH17) cells are important mediators involved in the pathogenesis of SLE. The differentiation of naive CD4-T cells into TH17 cell lineage depends on HIF-1 via the facilitation of glycolysis and direct upregulation of a key transcription factor. In patients with lupus nephritis patients, HIF-1alpha expression was shown to be upregulated in both the glomeruli and the interstitium, and glomerular HIF-1 a expression was associated with the severity of renal histopathol.

Richardson, Alan E. published the artcileOrganic anions facilitate the mobilization of soil organic phosphorus and its subsequent lability to phosphatases, Recommanded Product: (S)-2-hydroxysuccinic acid, the main research area is soil organic phosphorus phosphomonoesterase phosphodiesterase phytase.

Organic anions commonly released from plant roots and microorganisms are widely reported to mobilize soil phosphorus (P). We characterized soil organic P that was mobilized by organic anions and assessed its amenability to hydrolysis by phosphatase enzymes. Six soils differing in organic P concentration were extracted with citrate, malate or oxalate solutions and incubated with preparations of phosphomonoesterase, phosphodiesterase, or phytase. Organic P compounds present in these extracts were putatively identified and quantified with solution 31P-NMR spectroscopy and the enzyme-labile P fractions were assessed by changes in molybdate-reactive P (MRP) concentration Organic P mobilization varied markedly among the organic anions. Extraction with 10 mM citrate was most effective and extracted 7.8-fold more total P than the water controls across all soils. Approx. 95% of the extracted P was non-MRP. The organic anions increased both the amount of P extracted and the proportion of the total extracted P that was phosphatase-labile. Phytase was generally the most effective enzyme with up to 60% of the total non-MRP being amenable to hydrolysis by phytase across all extracts The presence of inositol hexakisphosphates in the extracts, as well as other forms of organic P including nucleic acids and phospholipids, was verified by 31P-NMR with concentrations dependent on both organic anions and soil type. The combination of organic anions and phosphatases represents a key mechanism by which plants and microorganisms can enhance the bioavailability of soil P. This has important implications for understanding P dynamics in natural and managed ecosystems and for ongoing efforts to improve the P-acquisition efficiency of agricultural plants.

Brizuela, Natalia Soledad published the artcileWhey permeate as a substrate for the production of freeze-dried Lactiplantibacillus plantarum to be used as a malolactic starter culture, Name: (S)-2-hydroxysuccinic acid, the main research area is wine whey permeate malic acid fermentation Lactiplantibacillus green chem; Freeze-drying; Lactiplantibacillus plantarum; Malolactic fermentation; Whey permeate; Wine.

The aim of this work was to obtain freeze-dried biomass of the native Patagonian Lactiplantibacillus plantarum strain UNQLp 11 from a whey permeate (WP)-based medium and compare it with the growth in com. MRS broth medium. Survival and activity of the freeze-dried Lb. plantarum strain were investigated after inoculation in wine as a starter culture for malolactic fermentation (MLF). The effect of storage and rehydration condition of the dried bacteria and the nutrient supplementation of wine were also studied. The freeze-dried cultures from WP and those grown in MRS showed similar survival results. Rehydration in MRS broth for 24 h and the addition of a rehydration medium to wine as nutrient supplementation improved the survival under wine harsh conditions and guaranteed the success of MLF. Storage at 4°C under vacuum was the best option, maintaining high cell viability for at least 56 days, with malic acid consumption higher than 90% after 7 days of inoculation in a wine-like medium. These results represent a significant advance for sustainable production of dried malolactic starter cultures in an environmentally friendly process, which is low cost and easy to apply in winemaking under harsh physicochem. conditions.

Oliveira de Araujo, Talita published the artcilePaspalum urvillei and Setaria parviflora, two grasses naturally adapted to extreme iron-rich environments, COA of Formula: C4H6O5, the main research area is Paspalum Setaria iron root shoot; Chloroplast; Citrate; Ferritin; Iron plaque; Malate; Oryza sativa; Paspalum urvillei; Perls-DAB method; Setaria parviflora; Setaria viridis; Vacuole; μXANES; μXRF.

Paspalum urvillei and Setaria parviflora are two plant species naturally adapted to iron-rich environments such as around iron mines wastes. The aim of our work was to characterize how these two species cope with these extreme conditions by comparing them with related model species, Oryza sativa and Setaria viridis, that appeared to be much less tolerant to Fe excess. Both Paspalum urvillei and Setaria parviflora were able to limit the amount of Fe accumulated within roots and shoots, compared to the less tolerant species. Perls/DAB staining of Fe in root cross sections indicated that Paspalum urvillei and Setaria parviflora responded through the build-up of the iron plaque (IP), suggesting a role of this structure in the limitation of Fe uptake. Synchrotron μXRF analyses showed the presence of phosphorus, calcium, silicon and sulfur on IP of Paspalum urvillei roots and μXANES analyses identified Fe oxyhydroxide (ferrihydrite) as the main Fe form. Once within roots, high concentrations of Fe were localized in the cell walls and vacuoles of Paspalum urvillei, Setaria parviflora and O. sativa whereas Setaria viridis accumulated Fe in ferritins. The Fe forms translocated to the shoots of Setaria parviflora were identified as tri-iron complexes with citrate and malate. In leaves, all species accumulated Fe in the vacuoles of bundle sheath cells and as ferritin complexes in plastids. Taken together, our results strongly suggest that Paspalum urvillei and Setaria parviflora set up mechanisms of Fe exclusion in roots and shoots to limit the toxicity induced by Fe excess.

Zhang, Xuehua published the artcilePropelling microdroplets generated and sustained by liquid-liquid phase separation in confined spaces, Recommanded Product: n-Octanol, the main research area is microdroplets propelling liquid phase separation numerical simulation.

Flow transport in confined spaces is ubiquitous in technol. processes, ranging from separation and purification of pharmaceutical ingredients by microporous membranes and drug delivery in biomedical treatment to chem. and biomass conversion in catalyst-packed reactors and carbon dioxide sequestration. In this work, we suggest a distinct pathway for enhanced liquid transport in a confined space via propelling microdroplets. These microdroplets can form spontaneously from localized liquid-liquid phase separation as a ternary mixture is diluted by a diffusing poor solvent. High speed images reveal how the microdroplets grow, break up and propel rapidly along the solid surface, with a maximal velocity up to ~160μm s-1 , in response to a sharp concentration gradient resulting from phase separation The microdroplet propulsion induces a replenishing flow between the walls of the confined space towards the location of phase separation, which in turn drives the mixture out of equilibrium and leads to a repeating cascade of events. Our findings on the complex and rich phenomena of propelling droplets suggest an effective approach to enhanced flow motion of multicomponent liquid mixtures within confined spaces for time effective separation and smart transport processes.

Dixit, Rakhi Bajpai published the artcileSecretomics: a biochemical footprinting tool for developing microalgal cultivation strategies, Name: (S)-2-hydroxysuccinic acid, the main research area is biochem footprinting microalgal cultivation; Biochemical tool; Bioprocess monitoring; Microalgal cultivation; Operation cost; Principal component biplot.

Microalgae offer a promising source of biofuel and a wide array of high-value biomols. Large-scale cultivation of microalgae at low d. poses a significant challenge in terms of water management. High-d. microalgae cultivation, however, can be challenging due to biochem. changes associated with growth dynamics. Therefore, there is a need for a biomarker that can predict the optimum d. for high biomass cultivation. A locally isolated microalga Cyanobacterium aponinum CCC734 was grown with optimized nitrogen and phosphorus in the ratio of 12:1 for sustained high biomass productivity. To understand d.-associated bottlenecks secretome dynamics were monitored at biomass densities from 0.6 ± 0.1 to 7 ± 0.1 g/L (2 to 22 OD) in batch mode. Liquid chromatog. coupled with mass spectrometry identified 880 exometabolites in the supernatant of C. aponinum CCC734. The PCA anal. showed similarity between exometabolite profiles at low (4 and 8 OD) and mid (12 and 16 OD), whereas distinctly sep. at high biomass concentrations (20 and 22 OD). Ten exometabolites were selected based on their role in influencing growth and are specifically present at low, mid, and high biomass concentrations Taking cues from secretome dynamics, 5.0 ± 0.5 g/L biomass concentration (16 OD) was optimal for C. aponinum CCC734 cultivation. Further validation was performed with a semi-turbidostat mode of cultivation for 29 days with a volumetric productivity of 1.0 ± 0.2 g/L/day. The secretomes-based footprinting tool is the first comprehensive growth study of exometabolite at the mol. level at variable biomass densities. This tool may be utilized in analyzing and directing microalgal cultivation strategies and reduction in overall operating costs.
