Analysis of bacterial communities in rice straw silage with various strain inoculations. a Principal coordinate analysis (PCoA) of bacterial communities in rice straw silage inoculated with different strains. The 95% confidence ellipses are depicted in respective colors for diverse communities. Dashed circles in blue and red signify groups inoculated without Lac33 and with Lac33, respectively. b Shannon indices of different samples. Boxplots indicate median, 25th and 75th percentiles, while error bars represent standard deviations of three replicates. c Relative abundance of phylum and d genus in bacterial communities of distinct silage samples. CK, no inoculation; LB, inoculated with LB; Leu, inoculated with L. pseudomesenteroides; Lac17, inoculated with L. buchneri R17; Leu + Lac17, inoculated with L. pseudomesenteroides and L. buchneri R17; Lac33, inoculated with L. brevis R33; Leu + Lac33, inoculated with L. pseudomesenteroides and L. brevis R33; Lac17 + 33, inoculated with L. buchneri R17 and L. brevis R33; Leu + Lac17 + 33, inoculated with L. pseudomesenteroides, L. buchneri R17, and L. brevis R33
