VIBRIO AQUAMARINUS STRAIN, METHOD OF DETERMINING SAMPLE TOXICITY USING SAME AND TESTING CULTURE FOR DETERMINING SAMPLE TOXICITY Russian patent published in 2014 - IPC C12N1/20 C12R1/63 C12Q1/02 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to biotechnology and can be used for biotesting of toxicity of environmental media. The invention discloses a Vibrio aquamarinus bacterial strain, a method of determining toxicity of samples using said strain and use of the strain as a testing culture for determining chemical toxicity of samples. The method comprises measuring luminescence of the Vibrio aquamarinus VKPM V-11245 strain in the presence of at least one chemical toxicant of a sample, said toxicant being ZnSO₄ or CuSO₄ or K₂Cr₂O₇ or oil or diesel fuel or bilge water or phenol or a heavy metal. Luminescence of said strain is measured without a chemical toxicant and the measured luminescence levels are compared. Change in luminescence indicates toxicity of the analysed sample.

EFFECT: invention improves reliability of detecting toxic substances in the environment.
