| Abstract: | Cultural characteristic of one cellulose-decomposing stain of fungus from alpine grassland soil in eastern Qilian Mountains were studied.The results showed that this strains was able to grow at 5～35 ℃.The optimal cultural temperature and pH values for mycelial growth was 30 ℃ and 7.08 respectively.The strain has ability of salt and PEG stress tolerance.It varied in its viability on media containing different carbon and nitrogen nutrients.The preferential carbon and nitrogen source was lactose and soybean peptone,respectively.Compare to the 1.5% water agar medium,the growth of the stain was faster in ryegrass extract,but slower in clover extract.The growth of the mycelium was not significantly difference in medium with different natural cellulose extract. |
