通过对冬虫夏草头孢菌（Ｃｅｐｈａｌｏｓｐｏｒｉｕｍｄｏｎｇｃｈｏｎｇｘｉａｃａｅ）改良菌株Ａ１０的菌丝体液体发酵条件的研究，我们掌握了其菌丝生长规律。其生长曲线呈典型的微生物生长曲线特点；其发酵生长适宜温度为２６～２８℃，适宜ｐＨ值在５－７之间，接种量以５％（ｖ／ｖ）为佳；在整个发酵过程中，对发酵通气量要求不高。 By studying mycelial liquid fermentation conditions of modified strain A10 of Cephalosporium dongchongxiacae, we have mastered its mycelial growth pattern. The growth curve is typical of the growth curve of microorganism. The optimal fermentation temperature is 26-28 ℃, the optimum pH is 5-7, and the inoculum size is 5% (v / v). During the whole fermentation process , Less demanding on the fermentation aeration.
