“…Four intense diffraction peaks at 2θ values of 38.0°, 46.13°, 64.43°, and 76.61° were indexed to the 111, 200, 220, and 311 planes of silver reflections, respectively (Fig. 3) (Ganachari et al 2012). These results demonstrated that the nanoparticles synthesized from wheat straw were composed of nanocrystals with the structure of FCC (Lokina and Stephen 2011).…”

Silver nanoparticles (AgNPs) were synthesized with wheat straw biomass at room temperature using light irradiation. The reaction conditions were optimized, including the light intensity, biomass concentration, NaCl addition, and reaction time. The silver nanoparticles fabricated at the optimum conditions (light intensity 60,000 lx, biomass concentration 2 mg/mL, and reaction time 90 min) were characterized by UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR), and zeta potential. The TEM results showed that the silver nanoparticles were mostly spherical, with an average diameter of 17.2 nm. The zeta potential of AgNPs reached -21.6 mV. The XRD spectra showed that the AgNPs were highly crystalline, with four characteristic peaks. The FTIR of nanoparticles implied that alcohols and proteins may have a vital role in the formation and stability of AgNPs. The silver nanoparticles synthesized by wheat straw biomass revealed antimicrobial activity against Escherichia coli and Bacillus subtilis strains.

“…In FTIR spectra of manganese-polyaniline composites skeletal vibrations of PANI was observed along with two sharp peaks at 533 cm À 1 and 579 cm À 1 characteristics of antisymmetric stretching mode of the MnO 6 octahedra [22,32,38]. Appearance of peak around 1630 cm À 1 (OH stretching vibrations attached to metal oxide) and doublet below 600 cm À 1 indicates the presence of α-MnO 2 in the composite [39]. As we go down the graph, the peak corresponding to MnO 2 becomes intense and sharpened indicating the increase of manganese concentration in the composite.…”

Rock-inhabiting fungi were isolated for rock walls in Golubinka and Medova Buža littoral anchialine caves in Croatia and tested for their halotolerance. Isolates were identified as Cladosporium psychrotolerans, C. delicatulum, Mucor circinelloides, Rhizopus stolonifer, Aureobasidium pullulans var. pullulans, and Talaromyces diversus. Of them, T. diversus appears most resistant to cosmotropic (NaCl) and chaotropic (KCl) salts. It was also the most common species isolated from rock walls. Despite the negative influence of salinity on acid production, we propose that some fungal strains can be recognized as active agents in carbonate dissolution and as good competitors on rocks in saline environments. Anchialine caves can be a refugium for unique halotolerant fungi.
