We studied the characteristics of the utilization of carbohydrate substrates and the production of those hydrolyzing enzymes of the Tricholoma matsutake J-1 strain isolated from hardwood (Quercus sp.). In the culture medium, 5% glucose inhibited mycelial growth. The growth inhibition rate was remarkable in the Z-1 strain from softwood (Pinus densiflora) compared with that of the J-1 strain from hardwood. α-Amylase production varied with starches from different origins in contrast to mycelial growth. The range of the effect of 0.5%–15% soluble starch on vegetative mycelial growth was also investigated. The optimal concentration for mycelial growth was 15% for the J-1 strain but 10% for the Z-1 strain. Mycelial growth of the J-1 strain was strongly inhibited in PMML medium containing Sunpeal- CP prepared from sulfite pulp softwood waste, but that of the Z-1 strain was not inhibited by Sunpeal-CP. Moreover, mycelial growth of the J-1 strain from Quercus sp. dramatically decreased with the addition of CNF-HWSF (hot watersoluble fractions from corn fiber) to the PMML and PDL medium. However, inhibition by CNF-HWSF was not shown in the Z-1 strain from P. densiflora.
