摘要
利用平板培养和试管斜面培养探讨影响棘托竹荪菌丝体培养的理化因子:碳源、氮源、无机盐。结果表明:棘托竹荪菌丝体在平板中和试管中对碳源、氮源、无机盐的利用情况是相似的;无论是平板中培养还是试管中培养,黄豆粉、硫酸铵、硝酸钾、Na+都能促进棘托竹荪菌丝体的生长,乳糖、蛋白胨、尿素都会阻碍菌丝体的生长。棘托竹荪对氮源的需求最高,其次是无机盐,而对碳源的需求不是很高。
Using plate cultivation and test-tube slant cultivation ,the effect of the physical and chemical factors on the growth of Dictyophora echinovolvata mycelium were studied：carbon source, nitrogen source, inorganic salts. The results showed that： on using carbon source and nitrogen source, inorganic salts, Dictyophora echinovolvata mycelium was similar at both plate cultivation and test-tube slant cultivation.When using soybean meal,ammonium sulfate,potassium nitrate,sodium, it had the best growth.When using lactose as a carbon source, using peptone and urea as nitrogen source, Dictyophora echinovolvata mycelium had the worst growth. Overall, Dictyophora echinovolvata mycelium had a high demand for nitrogen source, followed by inorganic salt, and the last was carbon source.
