Quantitative analyses of microbial growth characteristics and interactions for Streptomyces R02, pathogen Rs1115, and strains CSC98 and CSC13. a Box plots comparing the impact of Streptomyces R02 supernatant on strain CSC13’s growth. b Box plots showing the influence of Streptomyces R02 supernatant on strain CSC98’s growth. c Box plots illustrating the effect of CSC98 supernatant on CSC13’s growth. d Impact of CSC13 supernatant on CSC98’s growth. e Co-culture of strain CSC98 with Rs1115. f Co-culture of strain CSC13 with Rs1115. g Effects of supernatants from strains CSC98 and CSC13 on the growth of Streptomyces R02. h Impact of supernatants from various strains and their combinations (excluding Streptomyces R02) on Rs1115 growth. i Effects of single and combined bacterial supernatants on Rs1115’s inhibition by Streptomyces R02 supernatant. Legend: R02_CSCXX indicates strain CSCXX treated with Streptomyces R02 supernatant. CSCXX_R02 indicates the biomass of Streptomyces R02 treated with strain CSCXX’s supernatant. CSCXX represents strain CSCXX alone. CSCAA_CSCBB shows strain CSCBB treated with strain CSCAA supernatant. RS indicates the growth of Rs1115 alone. Co_RS (e) and Co_RS (f) refer to Rs1115 in co-culture systems with strains CSC98 and CSC13, respectively. Co_CSCXX indicates strain CSCXX in co-culture with Rs1115. R02 only (g) represents the biomass of Streptomyces R02 alone. Rs only (h, i) represents OD₆₀₀ nm of Rs1115 alone. R02 only (i) represents OD₆₀₀ nm of Rs1115 treated with strain R02 supernatant. Co_culture (h, i) represents the co-culture of strains CSC13 and CSC98. Mix (h, i) denotes supernatant from mixed strains CSC13 and CSC98 in equal proportions
