Dynamics of chemical profile and microbial community in 3 consecutive years reveal Rhodococcus and Apiotrichum are potential microbes contributing to quality formation of Guang Chenpi.

Currently, there remains a debate regarding the functional microorganisms responsible for the quality formation of Guang Chenpi (GCP). Thus, the metabolite profiles and microbial diversity of GCP samples subjected to natural treatment versus those sterilized via electron beam irradiation were investigated over a three-year period. It was found the main constituents of GCP were influenced both by spontaneous changes and microbial activity.
