Detection of Cyanotoxins of Cyanobacterial (Microcystis aeruginosa) Strain Using Microtox® Bioluminescence Bioassay
Cyanobacterial bloom sample was collected from Muttukadu backwaters, Chennai, Tamil Nadu, India. The bloom sample was observed under the microscope. The sample was identified as containing primarily of Microcystis aeruginosa. The occurrences of toxic cyanobacterial blooms in aquatic environments, associated with animal deaths, were noticed on 1 June 2012 and have increased the need for rapid, reliable and sensitive methods to detect algal biotoxins. Microtox® bioluminescence assay determines the toxicity of microcystin produced by cyanobacterial bloom. It is suggested that the Microtox® bioluminescence assay may prove useful in the preliminary screening of cyanobacterial blooms for microcystin-based toxicity.
