The collected Cyanobacterial mats were transferred to a 20 liter plastic pot. The samples are physically fil-
tered through 2 mm mesh sieved and then diluted by tab water free from chlorine or any disinfecting agents. The
dilution was 1:1 ratio. Due to long period of laboratory experiments, the collection of Cyanobacterial mats was
repeated several times as required. This dilution assumed to produce 10 cells/ml
