摘要：

Debaryomyces hansenii Y-1, Debaryomyces nepalensis T18 and Bacillus atrophaeus TE-7, isolated in our laboratory, were used to investigate their effects when used alone or in combination (Y-1+TE-7, Y-1+T18, T18+TE-7)on the storage quality and disease resistance of mango fruit. The results showed that soaking treatment with Y-1+TE-7(1: 1, V/V) for 20 min significantly inhibited the spore germination of Colletotrichum gloeosporioides. Moreover, Y-1+TE-7 treatment could not only remarkably delay the changes in a* value, firmness, titratable acidity (TA) and soluble solids (TSS)content, but also enhance the activity of peroxidase (POD), phenylalanine amidase (PAL) and β-1, 3-glucan (GLU) from 6 to 21 days of storage compared with either alone. This combination reduced the activity of polyphenol oxidase (PPO) between 9 and 18 days of storage in comparison with either treatment alone. These observations suggest that Y-1+TE-7 treatment can effectively improve the storage quality and increase disease resistance in mango fruit, and it can be potentially applied to postharvest handling of mango fruit. © 2019, China Food Publishing Company.
