Phycocyanin is mainly produced by Arthrospira Sp., which is cultured in open ponds. Algal screening for identifying antiinfectious agents is fundamentally novel attempt in present research scenario. Arthrospira Sp. produces the bioactive molecules that are rich in protein content. In this work, we report the extraction and partial purification of Phycocyanin using ammonium sulphate precipitation and dialysis. Further, the partially purified phycocyanin is tested for the antimicrobial property against the selected pathogenic strains and found highest zone of inhibition on E. coli (22 ± 0.6 mm).
