PCR Identification of Aspergillus niger with Using Natural Additives for Controlling and Detection of Malformins and Maltoryzine Production by HPLC

Microwave-assisted preparation of a silver nanoparticles/N-doped carbon dots nanocomposite and its application for catalytic reduction of rhodamine B, methyl red and 4-nitrophenol dyes

“… 42 After addition of AgNO 3 , a new peak appeared at 420 nm consistent with the surface plasmon resonance of AgNPs. 32 However, the absorption peaks of NCDs disappeared. The effects of different concentrations of AgNO 3 and microwave irradiation time were also optimized on nanocomposite formation ( Fig.…”

“…Several publications concluded that the plant-based materials are accountable for reducing metal ions into metallic nanoparticles accompanied by capping to inhibit agglomeration. 32 In this work, we used a plant material derived NCDs to reduce and stabilise AgNPs. In our previous publication, we have prepared NCDs from Lantana camara berries and ethylenediamine as carbon and nitrogen sources, respectively.…”

“…To control their shape and size in nanoparticle synthesis, polymers, DNA and other efficient molecules are used as stabilizers. [31][32][33][34] But, these molecules on the surface of nanoparticles always hinder the reactants from approaching the active sites of nanoparticles and restricting their properties and lowering the activities. Hence, some procedures such as thermal treatment and washing have been established to eradicate molecules on nanoparticles' surface.…”

Mycotoxins associated with maize wastes treated with comprised capsule of Spirulina platensis biomass

“…Maintaining high quality grains and grain products necessitates monitoring for mycotoxins and mycotoxigenic fungi. In addition, accurate fungal identification is crucial for informing researchers about which mycotoxins may be present (Magnoli et al 2007;Hamed et al 2016;Abdelghany et al 2017). Mycotoxins of potential food safety concern can be produced by toxic fungi while grains are stored.…”

Fungal deterioration of limestone false-door monument

“…Early scientific papers suggested that the coexistence of living organisms on stone increased its sensitivity to damage through their water-binding capacity, the mineralogy, porosity, surface roughness and capacity to collect water and organic material will control its receptivity (Guillitte, 1995; Krumbein and Gobushina, 1995). Fungi have a major deteriogenic potential than bacteria, as they secrete more levels of organic acids (Palmer and Hirsch, 1991; Makky and Abdel Ghany, 2009; Abdel Ghany and Al Abboud, 2014; Abdelghany et al., 2017; Abdel Ghany et al., 2018), and have been detected on degraded stone buildings in temperate and tropical zones (Warscheid and Braams, 2000; Gaylarde and Gaylarde, 2005). In addition, these fungi may cause physical degradation of stone by the growth of hyphal networks through the pore space system (Urzi et al., 2000).…”
