47f: Bioadaptation to Low Doses of Xenobiotics in Aquaculture.

Agricultural and industrial activities are increasing pollution of water bodies with low doses of xenobiotics that have detrimental effects on aquaculture. The aim of this work was to determine the possibility of using 47f culture in fish aquaculture under the influence of low doses of xenobiotics as an adaptogen. An increase in the survival of individuals exposed to the xenobiotic bisphenol A solution and fed with the 47f was shown compared to control groups and, at the same time, the cytokine profile in the intestinal tissues of was also investigated. Analysis of differential gene expression of the 47f grown under the action of high concentrations of bisphenol A showed changes in mRNA levels of a number of genes, including genes of various transport proteins, genes involved in fatty acid synthesis, genes of transcriptional regulators, genes of the arabinose operon, and the gene. The identification of 47f proteins from polyacrylamide gel by mass spectrometry revealed L-arabinose isomerase, Clp chaperone subunit, ATP synthase subunits, pentose phosphate pathway and glycolysis enzyme proteins, which are likely part of the 47f strain's anti-stress response, but probably do not affect its adaptogenic activity toward .
