Abstract
In this study we evaluated the ability of Saccharomycopsis schoenii Nadson and Krassiln (UWO-PS 80-91) as biocontrol agent against plant pathogenic filamentous fungi P. expansum Link (UFMG 01-2002), P. italicum Wehmer (LCP 61.1199), and P. digitatum (Pers.: Fr.) (LCP 984263, LCP 68175 and LCP 4354). S. schoenii was able to reduce disease severity in oranges inoculated with all fungi. Among the phytopathogens, P. digitatum LCP4354 was the most virulent whereas P. digitatum LCP 68175 was the most susceptible to predation. The yeast was able to survive for 21 days on the fruit surface and did not produce lesions on oranges. Production of antagonistic substances by S. schoenii was not detected using standard techniques. Our results point to the potential use of S. schoenii to control postharvest phytopathogens in fruits. Este estudo avaliou a capacidade de levedura Saccharomycopsis schoenii Nadson & Krassiln (UWO-PS 80-91) em controlar o crescimento dos fungos fitopatogênicos Penicillium expansum Link (UFMG 01-2002), P. italicum Wehmer (LCP 61.1199), e P. digitatum (Pers.: Fr.) (LCP 984263, LCP 68175 e LCP 4354). S. schoenii reduziu a severidade da doença em laranjas inoculadas com todos os fitopatógenos testados. Entre estes fitopatógenos, P. digitatum LCP4354 apresentou a maior virulência enquanto que P. digitatum LCP 68175 foi o mais suscetível à predação. A levedura foi capaz de permanecer viável, sem produzir lesões na superfície dos frutos por 21 dias. Outra característica desejável observada foi a ausência de produção de substâncias antagonistas. Sendo assim, este trabalho evidência o potencial de utilização da levedura S. schoenii em protocolos de controle biológico de doenças pós-colheita em laranjas.
