Effect of Xylose Concentration and Temperature on Bacterial Colony Formation #2342625 (License: Personal Use)

This bar chart illustrates the impact of xylose supplementation (1%, 2%, and 5%) on bacterial colony formation under two incubation temperatures: 30°C (gray bars) and 37°C (teal bars). At 2% xylose, colony counts peak near 58-59 for 37°C and ~6 for 30°C; further increasing xylose to 5% does not significantly boost growth at 37°C but slightly reduces it at 30°C. The data suggest optimal induction occurs at 2% xylose and 37°C.
