Figure 1. Microbial networks in unidirectional assays. The networks show interactions between primary degraders: (A) B. bifidum JCM 1254; (B) B. thetaiotaomicron VPI-5482; and (C) B. infantis ATCC 15697 and secondary degraders (gray nodes in the network). Interactions in the network were classified as positive, blue arrows (OD620 monoculture OD620 unidirectional)
