caryophyllene content in the
fermentation broth obtained by fermenting cloves with this *Lichtheimia corymbifera* strain can be increased to over 11339.26 μg / L. Furthermore, this invention provides the application of this
fermentation system in the saccharification stage of baijiu (
Chinese liquor), which can significantly increase the β-
caryophyllene content in baijiu and improve its
aroma and
flavor quality. This invention features a stable process, mild conditions, significant effects, good compatibility with baijiu production processes, and promising prospects for industrial application.
