Prediction of CAZymes in gut microbiota of V. stejnegeri
The top four CAZymes in the gut microbiota of V. stejnegeri were
GT2 (9.28% ± 1.57%), GT4 (6.16% ± 1.79%), GH23 (4.06% ± 1.30%),
and GT51 (3.02% ± 1.00%) (relative abundance ≥ 3%) (Fig. 6). No
significant differences in α-diversity were detected in the gut
microbiota among the three populations (Kruskal-Wallis test, P > 0.05). PCoA also showed no significant differences in the
diversity of CAZymes among the three populations (Adonis R2 =
0.18, P = 0.26). However, LEfSe showed that CAZyme abundance
differed significantly among the three populations. Key CAZymes and
their categories for each population are provided in Fig. 7.
