A rapid resazurin bioassay for assessing the toxicity of fungicides.
Fai PB, Grant A. Fai PB, et al. Chemosphere. 2009 Mar;74(9):1165-70. doi: 10.1016/j.chemosphere.2008.11.078. Epub 2009 Jan 12. Chemosphere. 2009. PMID: 19138785
The fluorescence bioassay showed only a small response to pyrazophos and thiabendazole but these only inhibited growth at high concentrations so this may reflect low sensitivity of S. cerevisiae to these particular fungicides. ...
