Abstract

Addition of biotin to culture medium NL-406 significantly increased alkaloid yield during submerged cultivation of Claviceps sp. strain SD-58. Alkaloid yield was further enhanced by incorporating leucine in biotin-supplemented culture medium. Increased alkaloid production was associated with an increase in the lipid content of cells and in the number of chlamydospores. Biotin deficiency caused a reduction in alkaloid yield and a parallel decrease in lipid content and chlamydospore numbers.

摘要

在培养基NL - 406中添加生物素可显著提高麦角菌属菌株SD - 58深层培养过程中的生物碱产量。在添加生物素的培养基中加入亮氨酸可进一步提高生物碱产量。生物碱产量的增加与细胞脂质含量和厚垣孢子数量的增加有关。生物素缺乏导致生物碱产量降低,同时脂质含量和厚垣孢子数量也相应减少。
