| Abstract: | Changes in the composition of microbial complexes and their biochemical activity in soil in the vicinity of a strong source of HF emission have been studied. A sharp decrease of the biomass, the number of asporous bacteria and actinomycetes, and a smaller decrease of the number of microscopic fungi has been revealed, along with a decrease in the enzymatic and respiratory activity of contaminated soil with the relative increase in the fraction of sporiferous bacteria. On the basis of the response of introduced population of Bacillus subtilis to different doses of HF, NaF, Na2SO3 microbiological norm-fixing for technogenic soil ecosystems has been carried out. |
