摘 要：The objective of this study was to determine the effect of β-glucan on stress tolerances and biocontrol efficacy of Cryptococcus laurentii against Penicillium expansum in pear *** results showed that biocontrol efficacy and the population growth of *** harvested from nutrient yeast dextrose broth amended with p-glucan at 0.5%（NYGB） were significantly higher compared to that harvested from nutrient yeast dextrose broth（NYDB）.Moreover,the viability of *** under heat,oxidative and water stress was markedly improved by cultivating in *** addition,the activity of superoxide dismutase in yeast cells was induced after exposure to heat,oxidative and water *** results indicate that the application of(3-glucan might be an effective method to improve the stress tolerances and biocontrol efficacy of *** our knowledge,this is the first report regarding the function of(3-glucan in enhancing various stress tolerances of post-harvest biocontrol yeasts.
