Resumo: Alternaria sp. is a fungus that causes rot in several crops, causing damage to the agricultural production chain. Biological control agents constitute an alternative to reduce the use of pesticides in the crops, a social demand for modern agriculture. The aim of the present study is to demonstrate the antagonistic effect of the yeast Trichosporon asahii (3S44) on the mycelial development of Alternaria sp. and some in vitro mechanisms of action. Trichosporon asahii showed antagonistic activity towards Alternaria sp., presenting mycelial inhibition (57.47%). The assays indicated production of volatile organic compounds (VOCs), competition for nutrients, biofilm formation, production of killer toxins and β-1,3-glucanase as mechanisms of action of T. asahii. Collectively, our results showed the potential of T. asahii to control the mycelial development of Alternaria sp. and some mechanisms of action of this yeast for future biotechnological studies.

Agentes de controle biológico são uma alternativa para reduzir o uso de agrotóxicos nas lavouras, uma demanda social para a agricultura moderna. O objetivo deste trabalho é demonstrar o efeito antagônico da levedura Trichosporon asahii (3S44) no desenvolvimento micelial de Alternaria sp. e alguns dos mecanismos de ação in vitro. Trichosporon asahii apresenta atividade antagônica frente Alternaria sp., com inibição micelial (57,47%). Os ensaios indicaram a produção de compostos orgânicos voláteis (COVs), competição por nutrientes, formação de biofilme, produção de toxina killer e β-1,3-glucanase como mecanismos de ação de T. asahii. Coletivamente, os resultados demonstraram o potencial de T. asahii no controle do desenvolvimento micelial de Alternaria sp. e mecanismos de ação da levedura, para futuros estudos biotecnológicos.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Federal de São Carlos, Centro de Ciências AgráriasUniversidade Estadual Paulista Julio de Mesquita Filho, Instituto de Biociências, Departamento de Bioquímica e MicrobiologiaUniversidade Estadual Paulista Julio de Mesquita Filho, Instituto de Biociências, Departamento de Bioquímica e MicrobiologiaFAPESP: 02541-7CAPES: 001Grupo Paulista de FitopatologiaUniversidade Federal de São CarlosUniversidade Estadual Paulista (Unesp)Bosqueiro, Ariane SilvaBizarria, Rodolfo [UNESP]Rosa-magri, Márcia Maria2021-07-14T10:20:46Z2021-07-14T10:20:46Z2020-05-08info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article20-25application/pdfhttp://dx.doi.org/10.1590/0100-5405/220861Summa Phytopathologica.
