WebJul 12, 2013 · Phyllosphere bacterial isolates with the ability to degrade AHLs were screened by the bioassay method. The sensor strain C. violaceum CV026, producing the purple pigment violacein in the presence of short- to medium-chain AHLs , was used for the bioassay. Preliminary screening methods involved cultivation of sensor strains and … WebA mouse bioassay was developed; unfortunately, this procedure requires purification fish extracts, since mice are not very sensitive to ciguatoxin. An alternative to the use of mice is the mosquito bioassay, which was recently used to obtain a dose-response relationship between ingested ciguatoxin and clinical symptoms in man.
