摘要
为紫拟青霉紫色色素的深入研究和开发应用提供参考,对紫拟青霉菌丝紫色色素的提取条件进行了研究。结果表明,紫拟青霉菌丝色素的最大吸收波长为530 nm,提取时以鲜菌丝直接浸提,提取剂以无水乙醇为宜,提取时间为180 min,提取时对菌丝进行破碎处理有助于色素的提取。
In order to provide references for further study and application of purple pigment produced by P.purpureus,the extraction conditions for purple pigment of this fungus were conducted.The results showed that the optimal absorption wavelength of the pigment was 530nm,fresh mycdium was more suitable than cry mycelium for pigment extraction,the best extraction solvent was absolute alcohol,and the optimal extraction time was 180 min.In addition,crushing the mycelium could be helpful for pigment extraction.
