  • a All data are presented as mean ± standard deviation (n = 2).

  • b The abundance is significantly different among Daqu and environments in workshops A and B. Significance is defined at P < 0.05 (with false discovery rate correction), as determined by a one-way ANOVA Duncan's test.

  • c ND, not detected.
