Patent ID: 6955912

Claim:
A process for producing chlamydospores which comprises inoculating a culture medium containing 2.0 to 3.5% by weight glucose, 0.3% by weight yeast extract, 0.3% by weight polypepton, 0.05% by weight magnesium sulfate, 0.05% by weight calcium chloride and 0.001% by weight antifoaming agent with Trichoderma harzianum SK-5-5 (FERM BP-4346) mycelia, the inoculation dose being 0.5 to 0.8% and pH adjustment being not conducted, propagating the mycelia at 27 to 29° C., 0.3 vvm aeration per 100 ml of the culture medium, and at an agitation speed after inoculation of 100 to 200 rpm, maintaining aerated cultivation while facilitating sporulation by augmenting the agitation speed by 15 to 30% afler glucose consumption in the medium, and separating formed mycelia, conidiospores and chlamydospores from the culture medium.
