| 摘 要： | Trichoderma aureoviride mutant T1010 was cultured in media containing different nutrients. Statistics showed significant differences and the results described below: The C/N tested were 3∶1, 6∶1, 12∶1, 24∶1,48∶1. The best C/N was 24∶1. The amount of spores was 4.0×109 cfu/plate. The best carbon source among glucose, sucrose, maltose, lactose, cellulose and starch was the last one. With a starch-containing medium, T1010 produced 5.3×109 cfu/plate. The asparagine was the best nitrog…

| Abstract: | Trichoderma aureoviride mutant T1010 was cultured in media containing different nutrients.Statistics showed significant differences and the results described below: The C/N tested were 3:1,6:1, 12: 1, 24: 1,48: 1. The best C/N was 24: 1. The amount of spores was 4.0×109 cfu/plate. The best carbon source among glucose, sucrose, maltose, lactose, cellulose and starch was the last one.With a starch-containing medium, T1010 produced 5.3 × 109 cfu/plate. The asparagine was the best nitrogen source. T1010 absorbed it easily and produced 9.6 × 109 cfu/plate. K, Mg, P, S, Fe were important to support T1010 growth and sporulation. In the absence of K, P, and Fe, Trichoderma grew poorly, while Mg didn' t seem to help Trichoderma colony development. A little amount of vitamins allwed T1010 to grow better. This data allowed us to improve the cultivation of Trichoderma at industrial level. |
