【摘要】 研究了蓝色梨头霉菌丝球形态与产率的关系 :摇床转速为 170r min、pH值为 6 5、底物添加量为 0 1%、单位体积孢子数为 1× 10 7个 mL、(NH4 ) 2 SO4 质量分数为 0 9%～ 1 8%、采用回转式的培养方法时 ,菌体直径一般在0 79～ 1 39mm ,且菌丝缠绕不过于紧密 ,菌丝球边缘菌丝较长 ,各球体之间较独立 ,此时转化率为 5 1%～ 5 6 4 %。更多还原

【Abstract】 The relations between morphology of Abasidia coerulea and productivity of hydrocortisone were investigated. The maximum conversion rate of R.S.A was obtained under the following conditions:rotation speed of the shaker 170 r/min, pH6.5, R.S.A 0.1%, concentration of spores 1×10 7cfu/mL, (NH 4) 2SO 4 0.9%～1.8%. The maximum conversion rate of R.S.A was 51%～56.4% when the diameter of myceliul pellet was between 0.79 and 1.39 mm.更多还原
