摘  要:
以巢湖打捞的新鲜蓝藻藻泥为处理对象,利用冻融破壁的方式获得藻蓝蛋白(phycocyanin,PC)粗提液。采取两步盐析初步纯化粗提液获得PC,再用纤维素(Cellufine A-500)阴离子交换树脂中度纯化PC,最后用羟基磷灰石(HA)柱高度纯化PC。结果表明,在室温25℃下,两步盐析(NH_4)_2SO_4的最佳摩尔浓度分别为1.0mol·L~(-1)和1.8 mol·L~(-1),PC纯度(A_(620)/A_(280))达到2.168,PC回收率可达37.5%。再经Cellufine A-500和HA两步柱层析纯化,PC纯度(A_(620)/A_(280))分别达到3.211和4.133,回收率分别为20.3%和7.2%,纯度达到试剂级纯度要求。

摘  要:
The fresh algae mud from Chaohu was used to obtain the crude extract of phycocyanin(PC) using freezing and thawing. The crude extract was purified by two-step salting-out, and the PC was purified by cellulose(Cellufine A-500) anion exchange resin and finally purified by hydroxyapatite(HA) column. The results showed that At room temperature(25℃), the optimum molar concentrations of two-step salting-out(NH_4)_2SO_4 were 1.0 mol·L~(-1) and 1.8 mol·L~(-1), respectively. The PC purity(A_(620)/A_(280)) reached to 2.168 and the PC recovery was 37.5 %. The purity of PC(A_(620)/A_(280)) reached 3.211 and 4.133, respectively, and the recovery was 20.3% and 7.2%, respectively, which reaches the reagent grade purity.
