In the present investigation, fucoxanthin—one of major pigments in diatoms—has been extracted from Nanofrustulum shiloi SZCZM1342, and its reducing efficiency biogenesis gold nanoparticles (GNPs) was checked. Fucoxanthin golden-brown cells N. compared to healthy, growing biomass standard fucoxanthin after separate exposure 25 mg L−1 aqueous hydrogen tetrachloroaurate solutions at room temperature. Isolated were found be able reduce ions within 12 h whereas, whole turned pink color 72...
Nanostructures-assisted laser desorption/ionization mass spectrometry (NALDI-MS) is gaining attention for the analysis of a wide range molecules. In this present investigation, Pseudostaurosira trainorii mediated biosynthesized iron-oxide nanoparticles (IONPs) have been utilized as nanostructures assisting ionization and desorption (LDI-MS). The chain forming diatom, P. showed efficiency in production IONPs against 0.01 M Fe+3 (pH 2) aqueous solution at intracellular extracellular level....
Fabrication of flower-like nanostructures are gaining attention because their high surface/volume ratio and extensive adsorption capacity. In the present investigation, flower-shaped, autofluorescent silver-silica (Ag-SiO2) hybrid nanoparticles have been fabricated exploiting diatoms as a source nanosilica. Two different species Gedaniella including G. flavovirens mutabilis showed efficacy in synthesizing fluorescent Ag-SiO2 nanoflowers (NFs) nanospheres (NSs) against 9 mM silver nitrate...
Industrial wastes with hazardous dyes serve as a major source of water pollution, which is considered to have an enormous impact on public health. In this study, eco-friendly adsorbent, the porous siliceous frustules extracted from diatom species Halamphora cf. salinicola, grown under laboratory conditions, has been identified. The architecture and negative surface charge pH 7, provided by various functional groups via Si–O, N–H, O–H these surfaces, revealed SEM, N2 adsorption/desorption...
Abstract In the present paper, for first time ability of porous biosilica originated from three marine diatom strains ‘ Nanofrustulum spp.’ viz. N. wachnickianum (SZCZCH193), shiloi (SZCZM1342), cf. (SZCZP1809), to eliminate MB aqueous solutions was investigated. The highest biomass achieved under silicate enrichment and (0.98 g L −1 DW 0.93 respectively), 15 °C N . (2.2 DW). siliceous skeletons were purified with hydrogen peroxide characterized by SEM, EDS, 2 adsorption/desorption, XRD,...
