Synthesis of silver nanoparticles (AgNPs) by Fusarium concolor and inhibition of plant pathogens

Abstract: O uso de nanopartículas (NPs) na agricultura, representa uma importante inovação tecnológica, utilizada na produção de nanofertilizantes, nanocidas ou pesticidas encapsulados em nanopartículas para liberação controlada. As NPs de prata são reconhecidas por suas aplicações na agricultura, biotecnologia, medicina. Este trabalho teve como objetivo estudar a síntese de nanopartículas de prata por Fusarium concolor endofíticos obtidos de folhas e sementes de guaranazeiro e avaliar a atividade antifúngica das nanopa… Show more

“…Species falling under this complex have also been known to treat poplar chemi-thermomechanical pulp to inhibit light-induced yellowing and enhance the brightness of the pulp ( Daolei et al, 2020 ). Reports also establish the usage of an endophytic Fusarium concolor in synthesizing silver nanoparticles ( Almeida et al, 2021 ). This newly isolated strain may be used for similar applications, such as the pretreatment of lignocellulose materials before bio-pulping or the bioconversion to fuel ( Li et al, 2008 ).…”

“…Fusarium concolor was first established on Hordeum vulgare from Montevideo, Uruguay ( Reinking, 1934 ) and later was reported from various hosts, such as wheat, banana, koa tree, Guarana, Hybanthus prunifolius , plant debris, and soil ( Chambers, 1972 ; Saadabi, 2006 ; Murad and Baiti, 2017 ; Almeida et al, 2021 ). It has also been known to cause keratitis and fusariosis ( Al-Hatmi et al, 2016 ).…”

“…In particular, silver nanoparticles (AgNPs) have garnered significant attention due to their unique antimicrobial properties, rendering them effective against a range of phytopathogens (Anees et al, 2020). Among the innovations, AgNPs synthesized by endophytic Fusarium concolor have shown efficacy in the in vitro control of fungal phytopathogens, including Colletotrichum guaranicola (Almeida et al, 2021). Moreover, in phytopathogenic fungi, smaller-sized nanoparticles have demonstrated greater toxicity than their larger counterparts.…”

“…Os nanomateriais atualmente são definidos por diferentes agências internacionais com base em sua função, forma, carga, proporção de área superficial, volume e outas propriedades físicas ou químicas (B. . Assim, a nanotecnologia tem atraído à atenção de pesquisadores devido o impacto que os produtos nanoestruturados podem causar na melhoria da qualidade de vida das pessoas (Almeida et al, 2021).…”

“…As nanopartículas são estruturas com tamanho entre 1 a 100 nanômetros (nm) que podem ser sintetizadas por métodos físicos, químicos e biológicos. Os métodos físicos e químicos requerem alto aporte energético, geralmente envolvendo o uso de substâncias tóxicas com geração de subprodutos perigosos (Almeida et al, 2021). Ao contrário a síntese biológica de nanopartículas de prata oferece vantagens pelo rápido e alto rendimento em relação aos métodos convencionais.…”
