a
The values are the averages for duplicate estimates obtained in two independent experiments. The variations were always less than 10%.
b
ND, not detected; +, number of CFU per gram of cork after incubation was more than 5.5 × 105 CFU; −, number of CFU per gram of cork after incubation was less than 4.5 × 105 CFU.
