Abstract:
... In Arabidopsis thaliana, NAC-like and activated by AP3/PI (NAP) are NAC transcription factors that regulate leaf senescence and environment stress. Gene LbNAP, which has a typical NAC region, was cloned from lily petals. Our results indicated that LbNAP was located in the nucleus, and the gene had transcriptional activation activity. Further studies on LbNAP expression showed that it was lowest in ...

Abstract:
... We present a qNMR method for the determination of low calories sweeteners (erythritol, mannitol, maltitol, sorbitol, isomalt and xylitol) in sugar-free foodstuff. The structural similarities of these compounds determine often a severe spectral overlap that hampers their quantification via conventional 1D and 2D NMR spectra. This problem is here overcome by exploiting the resolving capabilities of ...

Abstract:
... In vitro experiments were conducted to study the responses of potato (Solanum tuberosum L.) genotypes to osmotic stress. In vitro shoot cultures of 27 breeding lines and their drought-tolerant parents (referent lines: C103 and C107) were tested under osmotic stress induced by addition of PEG 6000 (Mw = 6000; 5.0, 7.5, 10.0%, w/v), D-mannitol (0.1, 0.2, 0.3 M) and PEG 600 (Mw = 600; 2.5, 5.0, 7.5%, ...

Abstract:
... MAIN CONCLUSION: Sorbitol metabolism plays multiple roles in many plants, including energy and carbon enrichment, effective defence against various stresses and other emerging specific roles. The underlying mechanisms are, however, incompletely understood. This review provides the current state-of-the-art, highlights missing knowledge and poses several remaining questions. The basic properties of ...

Abstract:
... The purpose of developing this high throughput assay was to determine whether there was evidence of pH adaptation in strains of rhizobia which nodulate subterranean clover (SC) and white clover (WC), and whether this was related to the pH of the soil of origin. pH is a first-order factor influencing the niche preferences of soil microorganisms and has been convincingly shown to be a key driver of ...

Abstract:
... The condensative cyclization of sp³ C–O bonds in per-silylated hexitols is investigated by computation. Conformer searches using the Monte Carlo algorithm, followed by successively higher levels of theory (MMFF, PM3, and B3LYP), of −SiR₃⁺- and −Bcat⁺-activated substrates lead to structures primed for intramolecular chemistry. Silane activation features O4 to C1 attack, while borane activation sugg ...

Abstract:
... The present study explored the use of mannitol and mannitol-rich agro-industrial wastes as substrates for PHB production by Cobetia amphilecti isolated from the green Ulva sp. seaweed. Cultivation of C. amphilecti on mannitol, celery, and olive leaves (OLs) waste led to 4.20, 6.00, and 5.16 g L⁻¹ of cell dry mass (CDM), 76.3, 25.5, and 12.0% of PHB content in CDM and 3.2, 1.53, and 0.62 g L⁻¹ of P ...

Abstract:
... Mushrooms and truffles are attracting attention as a new generation of biotherapeutics. In the current study, isolation, phenolic and organic acid composition, and antioxidant, cytotoxic, anticholinesterase activities of truffle Reddellomyces parvulosporus were examined. Four known compounds (brassicasterol (1), ergosterol peroxide (2), fumaric acid (3) and mannitol (4)) were isolated with the com ...

Abstract:
... In this work, it is described a novel micro-nanoplatform for pulmonary administration of active ingredients (AIs), including chitosan (CS)-based nanocapsules (NCs) with/without hyaluronic acid (HA), to treat lung diseases. Specifically, CS NCs and HA/CS NCs were microencapsulated in mannitol microspheres (Ma MS) by a simple spray-drying technique that gave as result dry powders of suitable charact ...

Abstract:
... The model wine system was established in this paper to explore the changing mechanism on the production of xanthylium cation pigments derived from (+)-catechin dimers linked by carboxymethyl bridge under microwave irradiation. The results showed that four xanthylium cation pigments in the visible region at 440 nm were obtained at low power, short time, and multiple microwave treatments. More xanth ...

Abstract:
... BACKGROUND: L-Ornithine is an important medicinal intermediate that is mainly produced by microbial fermentation using glucose as the substrate. To avoid competition with human food resources, there is an urgent need to explore alternative carbon sources for L-ornithine production. In a previous study, we constructed an engineered strain, Corynebacterium glutamicum MTL13, which produces 54.56 g/L ...

Abstract:
... In freeze-drying, the detection of the end of primary drying is a crucial aspect for both the process economics and product quality. Furthermore, the extreme process conditions (low temperature, high vacuum, and sterility) require monitoring devices with a high degree of assurance. In this paper, the most promising methodologies for the detection of the end point of primary drying were investigate ...

Abstract:
... Seed germination is the first step of seedling establishment, which is particularly sensitive to drought stress. Elucidating the mechanism regulating seed germination under drought stress is of great importance. We showed that overexpressing Tomato Ethylene Responsive Factor 1 (TERF1), an ERF transcription factor in the ethylene signaling pathway, significantly reduced seed sensitivity to mannitol ...

Abstract:
... BACKGROUND: Traumatic brain injury (TBI) is a structural injury or physiological disruption of the brain induced by an external force. The cerebellum facilitates movement coordination and provides a sense of equilibrium; damage to this structure can cause a wide variety of symptoms, including ataxia or dystaxia, ocular motor dysfunction, and disequilibrium. TBIs localised to the cerebellum are rar ...
... Se in the form of sodium selenite was microencapsulated by spray – drying and added to a food matrix (yogurt) to study the potential improvement of its bioaccessibility. Yogurt samples were also supplemented with Se in free salt form. Se-loaded microparticles were successfully prepared by spray-drying with production yields above 70%. The supplementation of yogurt with Se in the form of free sodiu ...

Abstract:
... Saccharides, especially anhydro sugars present in atmospheric aerosols, can be used as tracers to track sources of atmospheric aerosols. High‐performance anion‐exchange chromatography with pulsed amperometric detection is a commonly used technique for determining these saccharides, but the reported methods suffer from three drawbacks. First, to achieve separation of the complete set of atmospheric ...
... Setaria viridis, the wild ancestor of foxtail millet (Setaria italica), is an effective model plant for larger C₄ crops because S. viridis has several desirable traits, such as short generation time, prolific seed production and a small genome size. These advantages are well suited for investigating molecular mechanisms in angiosperms, especially C₄ crop species. Here, we report a procedure for is ...
... Liamocins synthesized by Aureobasidium spp. are glycolipids composed of a single mannitol or arabitol headgroup linked to either three, four or even six 3,5-dihydroxydecanoic ester tail-groups. The highest titer of liamocin achieved was over 40.0 g/L. The substrates for liamocins synthesis include glucose, sucrose, xylose, mannitol, and others. The Pks1 is responsible for the biosynthesis of the t ...
... Chocolate is one of the most popular sweets in the world. In recent years, the bean-to-bar process for chocolate production has attracted global attention. Bean-to-bar is a method of managing the whole production process from cocoa beans to chocolate bars, including single-origin chocolate (SOC). Many manufacturers aim to produce high-quality chocolate to maximize the flavor of cocoa beans. Howeve ...
... The effect of processing techniques (soaking, roasting and microwave irradiation) on biochemical parameters of groundnut, especially resistant starch (RS) and non-resistant starch (NRS), along with phytic acid (PA), iron (Fe), PA/Fe molar ratio and sugars were studied. Changes in RS and NRS content after processing have not been reported yet. Roasting for 12 min at 160 °C caused an increase in RS ...
