Phenol degradation experiments were performed in 250
ml Erlenmeyer flasks containing 40 ml of liquid mineral
medium plus phenol (1–10 mM). The flasks were aseptically
inoculated with five 5 mm disks obtained from the outer
edge of an actively growing culture and incubated on a rotary
shaker at 30 ◦C. Growth and substrate consumption were
determined at 24 h intervals.
