Unsupervised hierarchical cluster analysis (HCA) of the metabolite profile of B. breve DSM 20213 + linoleic acid (LA) vs B. breve DSM 20213 (similarity: ‘Euclidean’; linkage rule: ‘Ward’) following 48 h of exposure. Compound intensity was used to build up the heat map, on the basis of which the clusters were generated. This figure was generated in Mass Profiler professional version B.12.04 (Agilent technologies).
