Fig. 1From: Clean recovery and recycling of seasonal surplus forage grass by microbial driven anaerobic fermentation: a case study of napiergrassBacterial community diversities of fresh and fermented napiergrass harvested at different harvest dates. A Alpha diversities (Shannon, Chao1, Ace, Sobs, Simpson and Coverage indexes) of bacterial community; B beta diversities of bacterial community, calculated by three-dimensional principal coordinates analysis (3D-PCoA) based on the Bray–Curtis distance metric; C PCoA plot of NI and NII; D PCoA plot of NNI-7 and NNII-7; E PCoA plot of NNI-30 and NNII-30; F PCoA plot of NI, NNI-7 and NNI-30; G PCoA plot of NII, NNII-7 and NNII-30. 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 stageBack to article page
