Microbial diversity on grape surface and its research status
2023
Yao, Meiling
The microbial diversity of grape surfaces, also known as "microbial terroir", plays a critical role in winemaking and has applications in crop health and plant protection. Next-generation Sequencing (NGS) has revolutionized our understanding of grape surface microbiota by providing insights into the complex and dynamic microbial communities present on grape berries. NGS studies have confirmed the existence of distinct regional differences in grape surface microbial diversity, highlighting the concept of microbial terroir. This diversity is influenced by various natural and human factors, such as soil type, climate, vineyard management practices, and grapevine genetics, which contribute to the unique microbial terroir of each location. The application of NGS in studying microbial terroir has not only advanced our knowledge of grape and wine science, but also has implications in crop health and plant protection. The identification and characterization of microbial communities using NGS can help to develop sustainable and eco-friendly strategies for managing grapevine diseases and pests. The ongoing research in this area is expected to further expand our understanding of microbial terroir and its applications, contributing to the advancement of grape and wine science, and promoting environmentally responsible grape production practices. Based on bibliometric analysis, the current research focuses on the selection autochthonous S. cerevisiae, non-Saccharomyces and LAB. Plant growth-promoting bacteria considered as a new agroecological manageme. Interest in the role of natural microbial diversity in winemaking remains high.
