The Glycobiome network of <i>Megasphaera</i> sp.

<p>A) The glycobiome network of Human (red), <i>Megasphaera</i> sp. NM10, BL7 (green) and <i>M. elsdenii</i> DSM20460 (yellow). B) The glycobiome network of <i>Megasphaera</i> sp. NM10, BL7 (green) and <i>M. elsdenii</i> DSM20460 (red). CBMs- Carbohydrate-Binding Modules, GHs- Glycoside Hydrolases, GTs- Glycosyl Transferases, CEs- Carbohydrate Esterases. The nodes represent the CAZyme superfamilies and the edges are connecting the nodes based on the presence or absence of respective superfamilies in the organism.</p

Phylogenetic tree of family <i>Veillonellaceae</i> based on 16S rRNA gene.

<p>The phylogenetic tree was constructed in MEGA4 using neighbor-joining method. The bootstrap values (expressed as percentages of 1000 replications) are shown at branch points. The scale bar represents genetic distance (1 substitution per 100 nucleotides). Isolates in present study are in bold.</p
