摘要： The present study aimed to screen for dominant species involved in Baiyaojian fermentation based on the appearance and gallic acid content of Baiyaojian. The species were added via two routes: Jiuqu (dried fermentation starter) or distiller's grains. Baiyaojian was fermented with each individual species under the same fermentation conditions, and the dominant species was screened, isolated, and purified. Then, the dominant species from the two methods were compared to determine the optimal species for fermentation. One dominant species, each was isolated from Baiyaojian fermented with Jiuqu and distiller's grains. These species were subsequently identified as Rhizopus oryzae BYJ.G-1 and Aspergillus niger BYJ.H-1, respectively. The gallic acid content in the fermentation products of R. oryzae BYJ.G-1 was higher than that of A. niger BEI.H-1, and the surface of R. oryzae BEI.G-1 was covered with white hyphae. Both R. oryzae BYJ.G-1 and A. niger BYJ.H-1 were dominant species involved in the fermentation of Baiyaojian. R. oryzae BYJ.G-1 appeared to be more effective than A. niger BYJ.H-1. These findings suggested that single-species fermentation could be used to optimize the fermentation process of Baiyaojian and to improve its fermentation efficiency, thereby improving the quality of Baiyaojian as well as its safety for clinical use.
