The Effect of Additional Autopolyploidization in a Slow Growing Cellulase Hyperproducer of Trichoderma

Part of the ABAB Symposium book series (ABAB)


M14-2 is a cellulase hyperproducer derived from Trichderma reesei QM 6a, but with a growth rate lower than that of the original strain. When M14-2 was autopolyploidized followed by haploidization and selection, the strain with both a higher cellulase productivity per mycelia and a higher growth rate could be obtained as M14-2B. This strain seemed to be constructed using gene sources amplified by additional autopolyploidization.
