ABSTRACT
Fungi are known to produce a vast array of secondary metabolites that are gaining importance for their biotechnological applications. Early reports suggest that G. cingulata has the capability to transform many compounds by various enzymatic actions. Therefore, the focus of this study was to determine the antibacterial and antifungal activity of crude ethyl acetate extract of G. cingulata using agar cup bioassay method. Crude extract of G. cingulata exhibited remarkable antifungal activity against Rhizopus oryzae, Chrysoporium tropicum and Beauveria bassiana but no antifungal activity was found against Alternaria tenuissima and Aspergillus niger at any concentrations. The crude extract presented no antibacterial activity against Gram positive and Gram negative bacteria at any concentration.
RESUMO
Fungos são conhecidos produtores de uma vasta coleção de metabólitos secundários que vem mostrando importância crescente na sua aplicação biotecnológica. Publicações anteriores sugerem que G. cingulata tem a capacidade de transformar vários componentes por diferentes ações enzimáticas. Logo, o foco deste estudo foi determinar a atividade antibacteriana e antifúngica do extrato bruto de G. cingulata obtido por acetato de etila utilizando-se um método envolvendo bloco de agar. O extrato bruto de G. cingulata demonstrou marcante atividade antifungica contra Rhizopus oryzae, Chrysoporium tropicum e Beauveria bassiana entretanto, não foi possível detectar, em nenhuma concentração, atividade antifungica contra Alternaria tenuissima e Aspergillus niger. O mesmo extrato não apresentou atividade antibacteriana, em nenhuma concentração, contra bactérias Gram negativa e positiva.
