Biological Characteristics of Trichoderma Strain T41

Trichoderma T41 is a potential biocontrol fungus that was isolated from soil.Though it could grow on PSA,PMA,NA,Czapek and basic cultrure medium,PDA is the most favorable medium for the hypha growth and spore production.Temperature had distinct effect on the hypha growth and sporulation,from 10℃to 40℃ it could grow and produce spore,but the optimal temperature for the growth and sporulation of T41 was 30℃.For the basic culture medium,the glucose,xylose,fructose and maltose was optimal carbon source for hypha growth,glucose and fructose were propitious to spore production.Protein peptone was the best nitrogen source for hypha growth,protein peptone and asparagin were the best nitrogen source for spore production.The pH for hyphae growth and spore production ranged from 2 to 11,the optimal pH was 5.
