Bacterial co-occurrence networks analyses of fresh and fermented napiergrass harvested at different harvest dates. Bacterial co-occurrence networks of NI A, NII B, NNI-7 C, NNII-7 D, NNI-30 E and NNII-30 F. Nodes color indicates bacterial phylum and node size indicates its relative abundance. Edge are colored according to negative (green) and positive (red) correlations. E Comparison of node-level topological features (betweenness centrality and closeness centrality) in six networks. F Interaction type of the top 10 hub nodes with high degree. NI napiergrass harvested at the early vegetative stage, NII napiergrass harvested at the late vegetative stage, NNI natural fermentation of napiergrass harvested at the early vegetative stage, NNII natural fermentation of napiergrass harvested at late vegetative stage
