“…Salicornia bigelovii, known as dwarf glasswort, is a succulent halophytic (salt tolerant) plant proves to be a potential candidate to grow in salt marshes and intertidal areas on coasts of many countries (Loconsole et al, 2019) and can be irrigated with seawater (Glenn et al, 1998;Ventura and Sagi, 2013). There is an increasing concern about the use of S. bigelovii in human and animal diet as well as in biofuel production worldwide (Bañuelos et al, 2018;Doncato and Costa, 2018). In the UAE, the cultivation of S. bigelovii has become profitable.…”

Salicornia bigelovii is a promising halophytic cash crop that grows in seawater of the intertidal zone of the west-north coast of the UAE. This study assess plant growth promoting (PGP) capabilities of halotolerant actinobacteria isolated from rhizosphere of S. bigelovii to be used as biological inoculants on seawater-irrigated S. bigelovii plants. Under laboratory conditions, a total of 39 actinobacterial strains were isolated, of which 22 were tolerant to high salinity (up to 8% w/v NaCl). These strains were further screened for their abilities to colonize S. bigelovii roots in vitro; the most promising ones that produced indole-3-acetic acid, polyamines (PA) or 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase (ACCD) were selected for rhizosphere-competency under naturally competitive environment. Three outstanding rhizosphere-competent isolates, Streptomyces chartreusis (Sc), S. tritolerans (St), and S. rochei (Sr) producing auxins, PA and ACCD, respectively, were investigated individually and as consortium (Sc/St/Sr) to determine their effects on the performance of S. bigelovii in the greenhouse. Individual applications of strains on seawater-irrigated plants significantly enhanced shoot and root dry biomass by 32.3-56.5% and 42.3-71.9%, respectively, in comparison to noninoculated plants (control). In addition, plants individually treated with Sc, St and Sr resulted in 46.1, 60.0, and 69.1% increase in seed yield, respectively, when compared to control plants. Thus, the synergetic combination of strains had greater effects on S. bigelovii biomass (62.2 and 77.9% increase in shoot and root dry biomass, respectively) and seed yield (79.7% increase), compared to the control treatment. Our results also showed significant (P < 0.05) increases in the levels of photosynthetic pigments, endogenous auxins and PA, but a reduction in the levels of ACC in tissues of plants inoculated with Sc/St/Sr. We conclude that the consortium of isolates was the most effective treatment on S. bigelovii growth; thus confirmed by principal component and correlation analyses. To this best of our knowledge, this is the first report about

“…Figure S2 displays the complete spectrum obtained for the ADGFC residues for all electrocatalysts, qualitatively indicating the presence of the following products: glycerol 1044, 1115, 1223, 1323 and 1458 cm À 1 ; tartronate 1330 and 1630 cm À 1 ; oxalate 1447 and 1770 cm À 1 , formate 1345 and 1346 cm À 1 and carbonate 1064 and 1646 cm À 1 . [57][58][59] The integration of the FT-Raman spectrum bands demonstrated that Pd 2 Nb 1 /C and Pd 1 Nb 1 /C produced higher amounts of carbonate in relation to the other analyzed products (Figure 11). This suggests that the GOR for these electrocatalysts comprised a larger number of transferred electrons, i. e., the electrocatalysis was more effective and complete.…”

Niobium Enhances Electrocatalytic Pd Activity in Alkaline Direct Glycerol Fuel Cells

Pd x Nb y /C binary electrocatalysts supported on Printex 6 L carbon black were prepared by using an adapted chemical reduction method with sodium borohydride. The electrocatalysts were characterized by using SEM, TEM, XRD, EDS, ICP-MS, water contact angle and Raman spectroscopy. The best performance for the alkaline direct glycerol fuel cell (ADGFC) was obtained by using Pd 1 Nb 1 /C, which yielded a maximum power density of 27 mW cm À 2 at 70°C. Residues of products formed from the glycerol oxidation were analyzed by using FT-Raman and high-performance liquid chromatography (HPLC).The Pd 1 Nb 1 /C electrocatalyst exhibited a more negative onset potential for the CO oxidation reaction and a higher conversion rate of glycerol to carbonate. We suggest that the higher hydrophilicity, higher degree of disorder, and bifunctional effects enhanced the electrocatalytic activity of Pd, as Nb facilitated the oxidation of adsorbed CO in Pd and increased the transfer rate of electron from Pd to carbon black support Therefore, Nb is a promising co-catalyst for Pd-based electrocatalysts for ADGFCs.

“…Con relación a carbohidratos se ha reportado que Salicornia bigelovii contiene una gran cantidad de estos (Bañuelos, JA, Velázquez, I., Guerra, M. & Arjona, 2018;Cybulska et al, 2014), entre los que destacan la hemicelulosa y celulosa, esta última en cantidades elevadas, lo anterior hace que está halófita sea propuesta como una fuente importante en la industria sobre todo para la de los biocombustibles donde puede ser utilizada para la producción de bioetanol (Bañuelos, JA, Velázquez, I., Guerra, M. & Arjona, 2018). Por otra parte, (Cybulska et al, 2014), encontraron en muestras cultivadas en emiratos árabes alrededor de 9.1 g/ (100 g de muestra) de glucanos, 7,7 g/ (100 g muestra) de xilano, 5,5 ± 2,1 g / (100 g de muestra) de arabina y 1.9 -6.8 g / (100 g de muestra) de lignina evaluados en materia seca.…”
