    Abstract: Pu-erh tea is produced by a solid-state fermentation. The natural microbiota presented in pu-erh tea influence caffeine level. In previous study, one effective fungi was selected from pu-erh tea and identified as Aspergillus sydowii NRRL250, which could lead caffeine degradation. In this paper, A. sydowii NRRL250 was inoculated into a liquid medium... Show More
