Sheng, Jie published the artcileComparative evaluation of the quality of red globe grape juice fermented by Lactobacillus acidophilus and Lactobacillus plantarum, Computed Properties of 106-32-1, the main research area is Lactobacillus grape juice quality fermentation ester octanoic acid aldehyde.

Basic anal., electronic senses and HS-SPME/GC-MS were used to evaluate the effects of single and mixed cultures of Lactobacillus acidophilus-26 and Lactobacillus plantarum-56 on the quality of fermented red globe grape (RGG) juice. The results showed that mixed culture fermentation was superior to single strain fermentation in terms of viable bacteria counts, consumption of total sugar (TS), total soluble solids, pH, functionality, and antioxidant properties of RGG juice (RGGJ). Whereas the aroma profiles of developing juices were dominated by abundant esters, acids, alcs., aldehydes, and aldehydes. Compared with the single inoculation, co-inoculation of the two species induced lactic acid fermentations, leading to accumulation of acetic acid, Et acetate, and 2-hexenol significantly. Moreover, higher concentrations of Et acetate, benzoic acid Et ester, octanoic acid, sorbic acid, 2-phenylethanol, and 2-hexenol represented the characteristic flavours of juices. To sum up, these findings suggested that L. acidophilus-26 and L. plantarum-56 could be used as fermented strains to ferment and improve the quality of RGGJ.

Dodds, Michael G. published the artcileModel-informed drug repurposing: Viral kinetic modelling to prioritize rational drug combinations for COVID-19, SDS of cas: 55981-09-4, the main research area is model drug repurposing COVID 19; COVID-19; combination therapy; modelling; repurposing; viral cell cycle.

Aim : We hypothesized that viral kinetic modeling could be helpful to prioritize rational drug combinations for COVID-19. The aim of this research was to use a viral cell cycle model of SARS-CoV-2 to explore the potential impact drugs, or combinations of drugs, that act at different stages in the viral life cycle might have on various metrics of infection outcome relevant in the early stages of COVID-19 disease. Methods : Using a target-cell limited model structure that has been used to characterize viral load dynamics from COVID-19 patients, we performed simulations to inform on the combinations of therapeutics targeting specific rate constants The endpoints and metrics included viral load area under the curve (AUC), duration of viral shedding and epithelial cells infected. Based on the known kinetics of the SARS-CoV-2 life cycle, we rank ordered potential targeted approaches involving repurposed, low-potency agents. Results : Our simulations suggest that targeting multiple points central to viral replication within infected host cells or release from those cells is a viable strategy for reducing both viral load and host cell infection. In addition, we observed that the time-window opportunity for a therapeutic intervention to effect duration of viral shedding exceeds the effect on sparing epithelial cells from infection or impact on viral load AUC. Furthermore, the impact on reduction on duration of shedding may extend further in patients who exhibit a prolonged shedder phenotype. Conclusions : Our work highlights the use of model-informed drug repurposing approaches to better rationalize effective treatments for COVID-19.

Andreu-Coll, Lucia published the artcileVolatile composition of prickly pear fruit pulp from six Spanish cultivars, Safety of Methyl decanoate, the main research area is Opuntia pulp volatile composition nonanol 1 hexanol; HS-SPME; Opuntia ficus-indica; alcohols; aldehydes; gas chromatography.

This research analyzed the volatile composition of the fruits pulp of six prickly pear cultivars (NT, NE, NO, NA, FR, and ORI) growing in Spain, by headspace solid-phase microextraction and gas chromatog. (GC-MS and GC-FID). A total of 35 compounds were isolated, identified, and quantified, with aldehydes, alcs., and terpenes being the predominant chem. families, and esters, ketones, linear hydrocarbons, and terpenoids being also found. Nonanol, 2,6-nonadienal, 1-hexanol, 2-hexenal, and D-limonene were the predominant compounds NT and FR cultivars showed the highest concentration of total volatile compounds On the other hand, NE and NO cultivars presented the lowest concentration Future studies on sensory evaluation are required to determine the sensory quality of the fruits of these Spanish cultivars.

Filannino, Pasquale published the artcileVolatilome and bioaccessible phenolics profiles in lab-scale fermented bee pollen, Application In Synthesis of 140-11-4, the main research area is fermented bee pollen volatilome bioaccessible phenolics; fermentation; flavonoids; lactic acid bacteria; phenolics; pollen; volatile compounds.

Bee-collected pollen (BCP) is currently receiving increasing attention as a dietary supplement for humans. In order to increase the accessibility of nutrients for intestinal absorption, several biotechnol. solutions have been proposed for BCP processing, with fermentation as one of the most attractive. The present study used an integrated metabolomic approach to investigate how the use of starter cultures may affect the volatilome and the profile of bioaccessible phenolics of fermented BCP. BCP fermented with selected microbial starters (Started-BCP) was compared to spontaneously fermented BCP (Unstarted-BCP) and to unprocessed raw BCP (Raw-BCP). Fermentation significantly increased the amount of volatile compounds (VOC) in both Unstarted- and Started-BCP, as well as modifying the relative proportions among the chem. groups. Volatile free fatty acids were the predominant VOC in Unstarted-BCP. Started-BCP was differentiated by the highest levels of esters and alcs., although volatile free fatty acids were always prevailing. The profile of the VOC was dependent on the type of fermentation, which was attributable to the selected Apilactobacillus kunkeei and Hanseniaspora uvarum strains used as starters, or to the variety of yeasts and bacteria naturally associated to the BCP. Started-BCP and, to a lesser extent, Unstarted-BCP resulted in increased bioaccessible phenolics, which included microbial derivatives of phenolic acids metabolism

Hranilovic, Ana published the artcileImpact of Lachancea thermotolerans on chemical composition and sensory profiles of Merlot wines, Synthetic Route of 106-32-1, the main research area is Lachancea Saccharomyces merlot sugar ethanol ethyl lactate malic acid; Ethyl lactate; Fermentation; Lachancea thermotolerans; Lactic acid; RATA sensory analysis; Wine acidification; Wine aroma.

Wines from warm(ing) climates often contain excessive ethanol but lack acidity. The yeast Lachancea thermotolerans can ameliorate such wines due to partial conversion of sugars to lactic acid during alc. fermentation This study compared the performance of five L. thermotolerans strains in two inoculation modalities (sequential and co-inoculation) to Saccharomyces cerevisiae and un-inoculated treatments in high sugar/low acidity Merlot fermentations The pH and ethanol levels in mixed-culture dry wines were either comparable, or significantly lower than in controls (decrease of up to 0.5 units and 0.90% volume/volume, resp.). The anal. of volatile compounds revealed marked differences in major flavor-active yeast metabolites, including up to a thirty-fold increase in Et lactate in certain L. thermotolerans modalities. The wines significantly differed in acidity perception, alongside 18 other sensory attributes. Together, these results highlight the potential of some L. thermotolerans strains to produce fresher wines with lower ethanol content and improved flavor/balance.
