PROBLEM TO BE SOLVED: To obtain a new chlamydospore of Trichoderma harzianum, usable as a microbial material or the like capable of suppressing pathogenic bacteria by readily germinating only by the impartment of water by removing nutrients from the mycelium of Trichoderma harzianum, culturing the obtained Trichoderma harzianum in a liquid starvation medium containing no vitamins, and separating the cultured material, and. SOLUTION: This new chlamydospore of Trichoderma harzianum obtained by removing nutrients from the mycelium obtained by culturing the Trichoderma harzianum, normally culturing the obtained Trichoderma harzianum in a liquid starvation medium containing no vitamins, and separating the cultured material, is useful as a microbial material or the like having activities capable of suppressing pathogenic bacteria by performing ready and active germination only by the impartment of water. The chlamydospore of the Trichoderma harzianum is obtained by culturing the Trichoderma harzianum in a nutrient medium, separating the mycelium from the nutrient medium, culturing the mycelium after removing the nutrient components in the liquid starvation medium, and separating the mycelium. |
