Thermotolerant wood rotting fungi isolated from northern Thailand and their potential uses in lignin degrading applications

One hundred and thirteen wood rotting taxa were isolated from northern Thailand. The isolate C. versicolor RC3 exhibited highly active growth at 37°C among 10 thermotolerant isolates including of strains ST40, TP7, TP16, NP14, NP18, NP21, NP26, NP27, 7M and C. versicolor strain RC3. Isolate RC3 was...
