The brine
shrimp lethality assay is a simple, rapid and
inexpensive bioassay for determining general toxicity
of samples. Usually, the eggs of Artemia salina Leach is used in brine solution.13 Here, the isolation
of an unusual metabolite named as nodularinol from
Nodularia sp. and FDA antimicrobial and brine
shrimp lethality assay to determine MIC and toxicity
of cyanobacterial extractives are reported.
