Evaluation of Aspergillus aculeatus GC-09 for the biological control of citrus blue mold caused by Penicillium italicum

Postharvest Technologies of Fresh Citrus Fruit: Advances and Recent Developments for the Loss Reduction during Handling and Storage

“…Biological control by microbial antagonists (bacteria, yeasts, fungi) is still under investigation as an alternative to the application of synthetic fungicides for disease control in the field and postharvest applications [8,[203][204][205][206]. Wang et al [8] provided an overview of representative recent research on antagonists used to manage postharvest fungal decay in citrus fruit.…”

“…Wang et al [8] provided an overview of representative recent research on antagonists used to manage postharvest fungal decay in citrus fruit. In a very recent study, Zhang et al [205] reported the antifungal activity results for the fermentation product of the endophytic fungus Aspergillus aculeatus GC-09 (minimum inhibitory concentration (MIC) = 0.3125 mg/mL) used to combat the spore germination and mycelial growth of P. italicum.…”

Evaluation of antibacterial activity of compounds isolated from the peel of Newhall navel orange

“…SEM analysis were performed according to a previous method (Zhang et al 2022) with slight modifications. Briefly, 1 mL of freshly cultivated bacterial cells (OD600 = 0.3) of Xcc was added into a sterilized flask containing 200 mL of NB medium, followed by the addition of compounds solution in DMSO to achieve a final concentration of 1.0 MIC.…”

Controle biológico de fungos fitopatogênicos em citros pós-colheita

“…Plant Cell Biotechnology and Molecular Biology,21,[118][119][120][121][122][123][124][125][126] A quitina obtida de cascas de frutos do mar, purificada in vitro, demostra atividade na redução do crescimento micelial linear dos fungos P. digitatum e P. italicum, in vivo apresentou redução na incidência de doenças pós-colheita de frutos de laranja e limão valência em comparação com o controle. O uso de produto fermentado obtido de Aspergillus aculeatus frente a P. italicum demostra atividade antifúngica em concentração 0,3125 mg/mL, o produto é capaz de invadir a membana do fungo e reduzir a atividade enzimática (Atalla et al, 2020;Zhang et al, 2022). Coutinho et al (2020), também aplicou a quitosana como fungicida, frente aos fungos Penicillium.…”

“…A. aculeatus retarda os sintomas do mofo azul provocado pelo fungo P. italicum, interrompendo a integridade da membrana celular do fungo. O trissulfeto de dimetila exibiu atividade antifúngica produzido com P. fluorescens exibiu atividade antifúngica nas concentrações 100 e 10 μL/L, inibindo 100% do mofo (Zhang et al, 2022;Wang et al, 2021).…”
