Fig 4. Effects of different carbohydrates on the biofilm formation of SQY 162.

The assays were performed in triplicate and quantified by measuring A₅₇₀ nm of crystal violet-stained wells rinsed with 80% ethanol and 20% acetone. The different letters above each bar refer to the Duncan’s test, p < 0.05. Control (amended with nothing). LB medium was amended with sucrose (Sucrose), fructose (Fructose), pectin (Pectin), xylan (Xylan), galactose (Galactose), lactose (Lactose), or glycerol (Glycerol) at a final concentration of 0.5% (w:v).
