Table 3 Occupation rate (μ) on different substrates. The values of the mean extension rate (v) of the P. chrysosporium colony are correlated with the growth measured by surface area occupation for the same time intervals. The coefficient of determination (R2) was calculated for each regression line
Growth rate | Occupied area | Radial expansion | ||||
|---|---|---|---|---|---|---|
23 h to 29 h (3 points) | 29 h to 52 h (4 points) | 29 h to 52 h (4 points) | ||||
