The cyanophycin granules from two-week-old cultures of the blue-green alga Anabaena cylindrica were isolated by sonication of the cells followed by differential centrifugation. These particles are composed of polypeptides containing only two amino acids, aspartic acid and arginine, and have a molecular weight between about 25,000 and 100,000.
通过对蓝藻圆柱鱼腥藻两周龄培养物进行细胞超声破碎,然后进行差速离心,分离出了藻青素颗粒。这些颗粒由仅含天冬氨酸和精氨酸两种氨基酸的多肽组成,分子量约在25,000至100,000之间。
