FL130 growth in mono-cultures and FL130-TWY1.1 co-cultures with or without IPTG supplementation. A–D FL130 growth in BG-11[co] medium added with 0 mM NaCl (A), 100 mM NaCl (B), 150 mM NaCl (C), and 200 mM NaCl (D). The *, **, and *** represent the significant difference of p < 0.05, p < 0.01, and p < 0.001, respectively, between axenic FL130 cultures and FL130-TWY1.1 co-cultures sampled at the same time without IPTG induction. # and ## represent the significant difference of p < 0.05 and p < 0.01, respectively, between axenic FL130 cultures and FL130-TWY1.1 co-cultures sampled at the same time with IPTG induction
