Jianqu fermentation with the isolated fungi significantly improves the immune response in immunosuppressed mice
Copyright © 2020 Elsevier B.V. All rights reserved..
ETHNOPHARMACOLOGICAL RELEVANCE: Jianqu, a classical formula of traditional Chinese medicine, is used clinically to treat symptoms like chill and fever headache, diarrhea and loss of appetite and act on patients with low immunity. However, the quality control of Jianqu fermentation is not well established, and its function in regulating the body's immunity still remains unclear.
AIM OF THE STUDY: The present study firstly assesses the structure and diversity of fungal community during Jianqu fermentation and then investigates the immune regulating function of Jianqu extract in mouse model.
MATERIALS AND METHOD: The high-throughput sequencing is conducted to analyze the diversity and distribution of fungal community during the fermentation process of Jianqu, and then fungi with a high frequency and relative abundance are isolated. The immunosuppressed mice are induced by using cyclophosphamide (CTX) and used to evaluate the immune regulating function of Jianqu extract from natural fermentation or directed fermentation, respectively.
RESULTS: With the fermentation, the diversity and distribution of fungal community significantly changed. The number of OTU (operational taxonomic unit) was gradually decreased from 223 ± 1 in the early phase to 201 ± 11 in the middle phase and to 175 ± 32 in the later phase of Jianqu fermentation. Generally, in genus level, Millerozyma, Debaryomyces and Rhizomucor showed a significant increase and became dominant in the mid or later phase of fermentation, while the Aspergillus displayed a decrease following the fermentation. However, Saccharomycopsis is a dominate species in surveyed samples. Next, six fungi strains with a high frequency and relative abundance, including Saccharomycopsis fibuligera, Millerozyma farinose, Hyphopichia burtonii, Rhizomucor pusillus, Lichtheimia ramosa, and Monascus purpureus, are isolated successfully. Interestingly, directed fermentation for Jianqu with the six isolated fungi strains could achieve similar morphological characteristics with the natural fermentation. Consistently, Jianqu extract from directed fermentation demonstrated a similar therapeutic effect on immune response as that of naturally fermented Jianqu.
CONCLUSIONS: We firstly showed the significant change of structural profiles of fungal communities during Jianqu fermentation, and successfully isolated six dominate fungi strains in Jianqu. Interestingly, directed fermentation for Jianqu with these isolated strains could achieve a similar morphological characteristics and immune-modulating function as natural fermentation. It was suggested that Jianqu fermentation with functional fungi instead of natural microbes provide a new approach for the improvement of the production and quality control of the traditional Chinese medicine of Jianqu.
