Culture growth rate (MEA, 25 °C, mm per day)
The mycelial growth rate on Malt Extract Agar as mm per day at 25 °C. The mycelial growth rate Kr at 25 °C was calculated as follows:
Kr = (R1 - R0) / (t1–t0)
R1 = R0 + Kr (t1–t0)
where R1 = colony radius at time t1, R0 = colony radius at time t0.
For fast growing species which may cover the plate in less than a week, measurements are usually taken after every day. For slow growing species measurements are taken until up to three weeks.
