ANTAGONISTIC INTERACTIONS OF CHLOROPHENOXYACETIC ACIDS-DEGRADING BACTERIA OF <i>RHODOCOCCUS, SERRATIA, BACILLUS </i>AND <i> PSEUDOMONAS</i> GENUS
Objective. Investigation of relationship between natural chlorophenoxyacetic acid bacteria-degrading strains of Rhodococcus, Serratia, Bacillus and Pseudomonas genera and the possibility of their joint application. Materials and methods. Pure cultures have been obtained by Koch's method. Identification of microorganisms was carried out according to the cultural-morphological, physiological and biochemical characteristics, as well as the principles of genetic typing by 16S rRNA gene sequence. Relationship between strains was investigated by the method of agar blocks. Results. It has been established that Bacillus subtilis 21SW, Pseudomonas aeruginosa 36 DCP, Rhodococcus sp. 17S and Serratia marcescens 22 S do not demonstrate antagonistic mutual influence, except the strain Serratia marcescens 22 S, capable of suppressing growth of Bacillus subtilis 21SW. The strain properties must be considered in their practical application. Conclusions Possible joint B. subtilis 21SW, P. aeruginosa 36 DCP, Rhodococcus sp. 17S and S. marcescens 22 S use for the environment bioremediation from halogenated aromatic derivatives has been carried out.
