Yeast biocontrol against green mold in pear orange postharvest

Abstract

The objective of this work was to evaluate the efficiency of the β enzyme and the mechanisms of action by means of a post-biological control solution of the orange-harvest type of the pear variety. The experiments were carried out at the Laboratory Center for Support to the Academic Unit of Garanhuns (CENLAG), belonging to the Federal University of Agreste of Pernambuco (UFAPE). The Completely Randomized Design (DIC) was used. The results were selected for analysis of variance, in triplicate (ANO), with a 5% probability level test (p < 0.05), using the statistical software Sisvar. See that killer activity was observed in 85.7% of the lovely yeasts. Candida peltata URM4681 showed the best production of β -1,3-glucanase between 1,071 and 5,422 U mL -1. In a design 23 in protein medium, it was a very large 4-fold, 3351-fold increase in their enzyme. trials in sit8, selected, 5%, reduction, in the number of infected treated with the when compared with the extractor. Regarding the evolution and severity of the disease, it is not known that the fruits treated with enzymatic extract did not differ statistically from those treated with the fungicides IMZ and TBZ both preventively. It was concluded that C. peltata URM4681 is a good biocontrol agent against green mold in citrus.
