Effect of marine yeasts and ulvan on the postharvest control of Penicillium italicum causal agent of blue mold in Persian lemon
Penicillium italicum is causing blue mold on citrus fruits. Its control is with synthetic fungicides, however, marine yeasts and ulvan are an alternative to synthetic agro-products. The objective of this study was to determine in vitro antagonism of yeasts against P. italicum and its effect with ulv...

| Sumario: | Penicillium italicum is causing blue mold on citrus fruits. Its control is with synthetic fungicides, however, marine yeasts and ulvan are an alternative to synthetic agro-products. The objective of this study was to determine in vitro antagonism of yeasts against P. italicum and its effect with ulvan in the control of blue mold in Persian lemon fruits. The effect of ulvan on P. italicum and yeasts was evaluated. In vitro antagonism was determined by confrontation between yeast-phytopathogen and competition for carbohydrates. The protection of fruits with yeasts and ulvan against P. italicum was evaluated and the severity and incidence of the disease and the expression of SOD, POX and CAT were determined. There was no effect of ulvan on microorganisms. In vitro, yeasts inhibited the phytopathogen. Carbohydrates decreased with yeast and P. italicum, and spore germination of the phytopathogen was inhibited. The incidence of P. italicum in the fruits was decreased by yeast and ulvan. POX, CAT and SOD were increased in the fruits with yeast and ulvan. The application of marine yeasts and ulvan may be an option in the control of blue mold in Persian lemon fruits. |
