Abstract:
The effects of several factors on the chlamydospores production of Trichoderma aureoviride T-33 during the fermentation were researched.Based on the results above, the orthogonal test was made to screen out the best prescription.The results showed that, the best single-factor conditions for the chlamydospores production of T.aureoviride T-33 were, liquid culture of oat powder, 30℃, pH4.0, 120r/min, 24 hours oscillate incubating as well as liquid culture volume of 80mL/bottle when the 250mL size triangle bottle was used.The result of orthogonal test showed that, the best prescription for temperature, pH and oscillating speed was 30℃, pH4.0 and 140r/min.3.37?10~ 7 spore/mL chlamydospores were obtained at this combined condition.
