The absolute and relative abundance of 17 bacterial strains from total 486 isolates were listed in the table. Percentage change (IR‐UN)/UN means the relative abundance of representative strains changes by irradiation.
IR: Irradiated samples; UN: un‐irradiated samples; +: The bacteria strain was only isolated in the irradiated sample; −: The bacteria strain was only isolated in the un‐irradiated sample.
