C. meneghiniana was used as a
negative algae control. The cyanobacterial specific 16S rDNA PCR resulted in a 782-bp partial fragment
for all of the algae strains. The phycocyanin operon was amplified and obtained 650-bp product from two
cyanobacterial strain. The amplification of all the mcy gene fragments (mcyA, mcyE, mcyA-cd, mcyAB,
