Isolation and antibacterial activity of anabaena phycocyanin

摘要

The isolation and antibacterial activity of anabaena phycocyanin were investigated. The result indicates that three kinds of protein ingredients: PC-A, PC-B and PC-C were obtained using high performance liquid chromatography. The estimated molecular masses of PC-A and PC-B were 14 to 18 kD. PC-B and PC-C had certain antibacterial activity on?Bibrio parahemolyticus,?Bacillus mucilaginosus?and?Sarcina lutea. In addition, PC-C had certain antibacterial activity on?Vibrio harveyi. PC-A did not possess antibacterial activity in the study.
