Abstract Background Atractylodes lancea is a traditional Chinese medicine, which typically requires more than 3–4 years of continuous cropping to obtain the underground medicinal components. With continuous cropping years, the quality and yields of A. lancea medicinal materials decrease, while pests and diseases increase. These aspects are intimately correlated with rhizospheric microorganisms. Methods This research paper employed high-throughput sequencing for its detection in soil that was cultivated for three years and never cultivated to clarify the relationship between the microbial diversity of the rhizosphere and continuous A. lancea cropping. Results The rhizosphere microbial community was altered following the continuous cropping of A. lancea. The bacterial diversity and richness were observed to decrease, while the fungal community diversity increased, and richness decreased. The total OUTs of the soil bacteria and fungi of unplanted and planted A. lancea were 59.58% and 37.65%, respectively. At the phylum level, the relative abundance of Proteobacteria, Gemmatimonadetes, Acidobacteria and Chloroflexi decreased, whereas the relative abundance of Mortierellomycota increased. At the genus level, Bradyrhizobium, Striaticonidium, Dactylonectria, Sphingomonas, Burkholderiaceae, Rhodanobacter, Arthrobacter, Scleroderma, Mortierella and Penicillium were significantly different between the two sample groups. Conclusions Our results revealed that following the cultivation of A. lancea, the rhizospheric microbial community was altered. This study preliminarily determined the

The microbiota of the pretreatment phase is crucial to the assembly of the microbial community in the saccharification of fuyu-flavor baijiu. This study investigates the shifts in microbial community diversity from the pretreatment of raw materials to the end of saccharification. High-throughput sequencing reveals that Lactobacillus, Weissella, and Bacillus in the bacterial community and Rhizopus, Candida, Pichia, and Aspergillus in the fungal community are predominant during raw material pretreatment and saccharification processes. Also, 11 bacterial genera, including Bacillus, Lactobacillus, Leuconostoc, Weissella, Lactococcus, and Acetobacter, and eight yeast genera, including Candida, Pichia, Saccharomyces, and Wickerhamomyces, were isolated from the initial saccharification stage by culture-dependent approaches. Sourcetracker analysis indicates that the cooling grains and rice husks were the main contributors to the bacterial community composition of the saccharification process, and Qu was the main contributor to the shaping of the fungal community structure during the saccharification process. Abundance variation of the predictive functional profiles of microbial communities encoding for key enzymes involved in pyruvate metabolism, starch and sucrose metabolism, and glycolysis/gluconeogenesis during the pretreatment and saccharification phases were inferred by PICRUSt2 analysis. The results of this study will be utilized to produce consistently high-quality fuyu-flavor baijiu via better controlling the shaping of microbial community structures during the pretreatment and fermentation processes.
