  • A new antagonistic yeast strain（ LZ5） was isolated from a mango orchard in Hainan Province. Antagonistic activity of this yeast strain was evaluated against postharvest anthracnose of mango fruit caused by Colletotrichum gloeosporioides through in vitro and in vivo assays. In vivo inoculation assay revealed that 1 × 108cfu·m L-1 of the yeast strain had significant biocontrol activity against C. gloeosporioides. The lesion diameter of the anthracnose pathogenic fungi was 5. 80 mm in the control and 0. 33 mm in the test group after 4 days of inoculation at 25°C,and 26. 3 mm in the control and 17. 6 mm in the test group after 6 days at 25°C,respectively,and the disease incidence was 100% in the control and 20% in the test group after 4 days of inoculation. Moreover,it was observed that the yeast strain LZ5 grew rapidly on the wounds of mango fruit. The yeast cell population increased 62. 6-fold 24 h after inoculation and was then stabilized for the rest of the storage period. The yeast strain LZ5 was identified as Meyerozyma guilliermondii.

Abstract: A new antagonistic yeast strain（ LZ5） was isolated from a mango orchard in Hainan Province. Antagonistic activity of this yeast strain was evaluated against postharvest anthracnose of mango fruit caused by Colletotrichum gloeosporioides through in vitro and in vivo assays. In vivo inoculation assay revealed that 1 × 108cfu·m L-1 of the yeast strain had significant biocontrol activity against C. gloeosporioides. The lesion diameter of the anthracnose pathogenic fungi was 5. 80 mm in the control and 0. 33 mm in the test group after 4 days of inoculation at 25°C,and 26. 3 mm in the control and 17. 6 mm in the test group after 6 days at 25°C,respectively,and the disease incidence was 100% in the control and 20% in the test group after 4 days of inoculation. Moreover,it was observed that the yeast strain LZ5 grew rapidly on the wounds of mango fruit. The yeast cell population increased 62. 6-fold 24 h after inoculation and was then stabilized for the rest of the storage period. The yeast strain LZ5 was identified as Meyerozyma guilliermondii.
