Volcano-plot statistical untargeted metabolomics comparison of the two fermentation formats tested for the strain CF-090361, comparing the different growth conditions (− log 10 of t-test statistical p-value in y-axis vs. − log 2 of ion masses areas ratio in x-axes): (A) culture in EPA vials; (B) culture in Flasks of 250 mL (m/z 219 and m/z 220 in red, m/z 205 and m/z 206 in purple, m/z 197 and m/z 198 in brown, m/z 223, m/z 241 and m/z 263 in yellow and m/z 322 in green). The number of statistically different mass ions due to higher production for each growth condition is indicated with statistical confidence of 95% (n = 10; α < 0.05) for each fermentation condition.
