Carbohydrates production in axenic FL130 cultures. A Sucrose and total carbohydrate in axenic FL130 cultures added with IPTG; B Sucrose and total carbohydrate in axenic FL130 cultures without IPTG addition. C Sucrose in axenic FL130 cultures in BG-11[co] plus 100 mM NaCl, with or without IPTG. D Measurement of cell biomass and extracellular carbohydrates in axenic FL130 cultures added with IPTG. E Measurement of cell biomass and extracellular carbohydrates in axenic FL130 cultures without IPTG. F Extracellular carbohydrates in the spent medium of axenic FL130 culture before and after inoculation with TWY1.1 spores. The spent medium of axenic FL130 cultures with variable salt (0, 100, or 200 mM NaCl) were collected at 6 days and inoculated with TWY1.1 spores. Subsequently, the contents of total carbohydrates were measured after 2 days of cultivation. The *, **, and *** represent significant difference of p < 0.05, p < 0.01, and p < 0.001, respectively
