Figure 18.

Concentration of S. aureus (a, b) in the broth with different beads and hydrotropic lignin after incubation for 24 h at 37 C. Inhibition of S. aureus growth calculated on the basis of the bacterial concentrations (c, only positive values are presented). (a and b) Runs were performed on two different days. Load of the beads and the dosages of lignin were the same as in the tests with E. coli. Initial concentrations of bacteria were 6.38 and 6.26 log(CFU/mL) for runs a and b, respectively. 90C10L denotes 90% cellulose, 10% lignin.
