Figure 1.

The values of oxytetracycline concentration (a), pH (b), glucose concentration (c), peak area corresponding to rimocidin (d), and desferrioxamine E (e) after 24, 48, 72, and 96 h of submerged co-cultivation of S. rimosus with S. noursei, A. niger, P. rubens, M. racemosus, or C. globosum in shake flasks. The inoculation with the use of spores was performed in all presented cases. The results are given as mean ± SD from three independent experiments (n = 3). The two-sample t-test was performed to indicate whether the results obtained for the co-cultures differed significantly from the ones recorded for the S. rimosus monoculture controls. * p ≤ 0.05, ** p ≤ 0.01, *** p ≤ 0.001, **** p ≤ 0.0001, ns—not significant. The peak areas are given in auxiliary units.
