Postharvest rot of blueberry fruits caused by led to huge economic losses in storage and transportation. In this study, T-2 was isolated from the surface of blueberry fruits and significantly reduced postharvest rot of blueberry fruits. The weight loss rate of T-2 soaked blueberry fruits was decreased; the contents of total soluble solids, titratable acidity and vitamin C of T-2 treated blueberry fruits were increased at a humidity of 85% and 25 °C. T-2 also enhanced the control of gray mold in blueberry fruits, but could not directly inhibit the growth of . The volatile organic compounds (VOCs) produced by T-2 could inhibit the growth of , and significantly reduced the postharvest rot of blueberry fruits. According to Gas Chromatography-Mass Spectrometry (GC–MS) analysis and antibacterial analysis, the benzyl alcohol, phenylethyl alcohol, benzaldehyde, 2-ethyl-1-hexanol, acetic acid, octanoic acid, 3-hydroxy-2-butanone, 2, 5-dimethyl-pyrazine and isoamyl acetate were selected. The influence of the above 9 volatiles on growth was assessed by treating with various concentrations of volatile. The lowest effective amounts of 9 volatiles were established to reduce the postharvest rot of blueberry fruits. These results shed light on the roles of T-2 VOCs in the control of postharvest blueberry fruits to , and provided a new method of postharvest storage.

Metschnikowia pulcherrima 酵母 T-2 产生的挥发性有机化合物抑制采后蓝莓果实中灰葡萄孢的生长

蓝莓果实采后腐烂导致贮运过程中造成巨大的经济损失。本研究从蓝莓果实表面分离出T-2，显着减少蓝莓果实采后腐烂。 T-2浸泡后蓝莓果实失重率降低； T-2处理的蓝莓果实的可溶性总固形物、可滴定酸度和维生素C含量在湿度85%和25℃下均有所增加。 T-2还增强了对蓝莓果实灰霉病的控制，但不能直接抑制蓝莓果实的生长。 T-2产生的挥发性有机化合物（VOCs）可以抑制蓝莓果实的生长，并显着减少蓝莓果实采后腐烂。根据气相色谱-质谱（GC-MS）分析和抗菌分析​​，苯甲醇、苯乙醇、苯甲醛、2-乙基-1-己醇、乙酸、辛酸、3-羟基-2-丁酮、2、选择5-二甲基吡嗪和乙酸异戊酯。通过用不同浓度的挥发物处理来评估上述9种挥发物对生长的影响。确定了 9 种挥发物减少蓝莓果实采后腐烂的最低有效量。这些结果揭示了T-2 VOCs在蓝莓采后果实中的控制作用，并为采后贮藏提供了新的方法。
