采用可见分光光度法测定螺旋藻藻粉中β-胡萝卜素含量,并对测定过程中有关β-胡萝卜素的提取工艺进行了优化,确定了最佳工艺参数为:提取剂为V(正庚烷):V(丙酮):V(无水乙醇):V(甲苯)=10:7:6:7,提取剂体积为30 mL,浸提时间为12 h,浸提温度为35℃.在该工艺下测得螺旋藻藻粉的β-胡萝卜素含量为134.15 mg/100 g.
A recombinant allophycocyanin trimer was successfully immobilized on a mesoporous TiO2 electrode. The formation of the immobilized surface was confirmed by multilayer adsorption of protein complexes. The key biophotovoltaic parameters were obtained,which showed that the recombinant allophycocyanin trimer could be a candidate for photosensitizer materials.The values of short-circuit current, open-circuit voltage,fill factor,and conversion efficiency were up to 0.73 mA/cm2,0.52 V,0.69,and 0.26%,respectively.
