Growth curve of Chryseobacterium species under saline conditions. Bacterial cultures were incubated at 30 °C in nutrient broth containing varying NaCl concentrations ranging from 1 to 5 %. The following strains were studied: (a) C. cucumeris GSE06 (CCU), (b) C. hispalense DSM 25574 (CHI), (c) C. phosphatilyticum ISE14 (CPH), (d) C. salivictor NBC122 (CSA) and (e) C. oleae DSM 25575 (COL). Bacterial growth was monitored by measuring the optical density at 600 nm (OD₆₀₀) using a UV spectrophotometer. Each point represents the average of three replicates, and error bars indicate the standard deviation of the mean. To enhance visual distinction, the lines are colour-coded with increasing darkness corresponding to higher NaCl concentrations.
