[Quantification of phenol compounds using Pseudomonas free bacterial cells].
The possibility of using Pseudomonas free bacterial cells for integral evaluation of some phenol compounds' content in water by means of estimation of specific respiratory activity (SRA) value was shown. Amperometric system of Clark electrode was used as a transducer in conducted investigations. The conditions of performing the SRA analysis of Pseudomonas sp. B 4251 and Ps. putida sp. microbial cells were optimized. The method sensitivity is 0.2 mM for Pseudomonas sp. B 4251 and 0.5 mM for Ps. putida sp. Taking into account specificity and sensitivity of the studied method, for estimating the integral toxicity of waste water, which contains 4-nitrophenol and 2,4-dinitrophenol in more than MPC concentrations and harmful for ecosystem became possible.
