In recent years, biocontrol on fruit postharvest diseases using antagonistic yeasts becomes a hot topic.

Selection of SOD high-producing strain of marine yeast and study on its fermentation conditions;

The new research progress about the properties and gene information of extracellular enzymes from marine yeast were reviewed in this article.

A total of 19 strains of marine yeasts which could produce cellulase were screened from the yeasts stored in the present laboratory, and strain 98 ,which was found to be able to produce a higher yield of cellulase, was selected for subsequent investigation.

In this study, the biocontorl efficacies for postharvest diseases of grapes and growth adaptabilities on the grapes surface were contrasted among 5 strains of antagonism yeasts.
