  • a n = 24.

  • b Check marks (✓) represent the samples that were sequenced based on 16S rRNA genes/ITS rRNA region.

  • c H, hard (more than 2.0 mmol/liter CaCO3); MH, moderately hard (1.5 to 2 mmol/liter CaCO3); SH, slightly hard (1.0 to 1.5 mmol/liter CaCO3); MS, moderately soft (0.5 to 1 mmol/liter CaCO3); S, soft (less than 0.5 mmol/liter CaCO3).
