Postharvest lemons are affected by several fungal infections, and as alternatives to chemical fungicides for combating these infections, different microbial biocontrol agents have been studied, with the Clavispora lusitaniae 146 strain standing out. Although strain 146 has proven to be an effective agent, the influence of a microbial biological control agent on the postharvest lemon microbiome has not been studied until now. Thus, this study aimed to evaluate how the epiphytic microbiome of postharvest lemons is affected by the application of the biocontrol yeast C. lusitaniae 146.
In terms of bacterial composition, the most abundant genera were Sphingomonas, Pelomonas, and Bacillus and no significant differences in the composition were detected between the treated and control samples. Among fungi, Clavispora was predominant not only in the treated samples but also in the control, and statistics indicated differences, suggesting its significant role in modulating the epiphytic community composition of lemon. Understanding fruit microbiomes is vital for effective disease control, and this study provides insights into the microbial composition of the surface of lemon and the role of C. lusitaniae 146.
采后柠檬会受到多种真菌感染，作为对抗这些感染的化学杀菌剂的替代品，人们研究了不同的微生物生物防治剂，其中葡萄牙棒孢酵母146菌株尤为突出。尽管146菌株已被证明是一种有效的防治剂，但迄今为止，微生物生物防治剂对采后柠檬微生物组的影响尚未得到研究。因此，本研究旨在评估生物防治酵母葡萄牙棒孢酵母146的应用如何影响采后柠檬的附生微生物组。
在细菌组成方面，最丰富的属是鞘氨醇单胞菌属、佩洛莫纳斯菌属和芽孢杆菌属，处理过的样品和对照样品之间在组成上未检测到显著差异。在真菌中，棒孢酵母不仅在处理过的样品中占主导地位，在对照中也是如此，统计结果表明存在差异，这表明其在调节柠檬附生群落组成方面具有重要作用。了解果实微生物组对于有效的病害控制至关重要，本研究为柠檬表面的微生物组成以及葡萄牙棒孢酵母146的作用提供了见解。
