摘要

Yeast plays a pivotal role in beer brewing, as its metabolic activity directly determines the flavor profile, product quality, and production efficiency of beer. With the rapid advancement of biotechnology, innovative techniques such as omics, adaptive evolution, and CRISPR-based genome editing have significantly accelerated the process of yeast strain breeding. These technologies not only enhance fermentation performance but also enable the targeted development of novel strains with specific phenotypic traits, thereby addressing diverse market demands for customized beer characteristics. This review systematically discusses current strategies for beer yeast breeding, with particular emphasis on recent technological breakthroughs in strain development. Furthermore, we provide insights into future trends in strain enhancement technologies, highlighting the importance of multidimensional strategies, high-throughput selection platforms, the synergistic integration of synthetic biology and computational modeling to achieve precise strain optimization. This review highlights that continuous technological innovation is crucial for enhancing yeast breeding efficiency and meeting the evolving demands of the industry.
