General information

Name of the project: Nanopumps for heavy metals


Goals and objectives

Research directions: Isolating new microorganisms – prokaryotes and eukaryotes, study of mechanisms of resistivity against heavy metals and applications of tolerant forms in biotechnologies.

Project objective:

  • Creation of the laboratory for biochemistry and molecular biology that will specialize in determining functions of heavy metal ion pumps and other proteins involved in homeostasis of heavy metals as well as development of new technologies of nanodiscs to investigate functions of ion pumps.
  • Development of technologies for expression, purification and research of new proteins on a wide scale
  • Development of nanodisc technologies and their applications to membrane ion pumps.
  • Decoding genomes of new sulfate reducing bacteria and analysis of mechanisms of resistivity against heavy metals.

The practical value of the study

Scientific results:

  1. We have demonstrated the leading role of sulfate-reducing Desulfovibrio in the formation of  hydrogen sulfate in animal farming waste and developed methods of dealing with the small at major  animal farming complexes.
  2. Our researchers have developed a strategy for the use of geometric information for isolating a culture of extremophilic organisms into a culture.
  3. We have developed a strategy and isolated Candidates Desulforudis audaxviator into a pure culture from the underground biosphere, which is viewed as a possible example of exoplanetary life.
  4. We have isolated metal-resistant Myxomycetes that participate in biomineralization  processes in acid mine drainage.
  5. Approaches have been developed for the use of continuous cultivation for isolating acidophilic microorganisms from acid mine drainage.
  6. New unique extremophiles have been isolated into a pure culture from underground waters.

Implementation of research results:
  • Conducting large-scale (within the territory of Russia) research of the gut microbiomes  of agricultural animals (AA) and dairy products of animal origin, produced with help from civic science tools (volunteering microbiologists). Information on microbial communities and their metagenomes will be used for the targeted isolation of producer strains and creating microbial consortia.
  • Our researchers have isolated Spirochaeta thermophila into a pure culture with the use of the metagenome (MAG). This organism constitutes an insignificant part in the microbial     community of deep water-carrying horizons and cannot be cultivated using traditional methods.
  • We have established possible consequences of excessive growth of CRP in the human intestine. It is the transition of biologically available iron into poorly soluble crystalline iron sulfides that cause iron deficit in the organism. The loss of iron through the formation of insoluble sulfides can occur in the proximal part of the gastrointestinal tract.
  • We have demonstrated the leading role of sulfate-reducing Desulfovibrio in the formation of hydrogen sulfate in animal farming waste and developed methods of dealing with the smell in major animal farming complexes.
  • Our researchers have developed a strategy for the use of genome information for isolating minor components of a community of extremophile microorganisms into a culture.
  • We have developed a strategy and isolated CandidatusDesulforudisaudaxviator into a pure culture from the underground biosphere, which we view as an example of exoplanetary life.
  • Our researchers have isolated metal-resistant Myxomycetes that participate in  biomineralization in acid mine drainage.
  • The Laboratory has developed approaches to the use of continuous cultivation for isolating acidophilic microorganisms from acid mine drainage.
  • We have isolated extremophiles into a pure culture from underground waters.

Education and career development:

The Laboratory has developed and delivered the lecture courses «General microbiology», «Biotechnology», «Environmental microbiology», «Industrial biology» at the Tomsk State University. We are supervising research work of master’s degree and postgraduate students specializing in «Microbiology», «Ecology» and «Plant physiology», 6 Candidate of Sciences dissertations have been prepared and defended, the last of them by Dmitry V. Antsiferov «Isolating sulfate-reducing bacteria promising for forming metal sulfides from acid mine waste and their cultivation» in 2017 in the direction 03.02.03 Microbiology. 

Collaborations:
The joint Russian Foundation for Basic Research grant «Diversity and activity of sulfidogenic microorganisms and preventing the formation of hydrogen sulfide on municipal and agricultural waste polygons».

Joint research is conducted in collaboration with:

  • Faculty of Biology, Lomonosov Moscow State University;
  • Kurchatov Institute;
  • Federal Research Center «Fundamentals of Biotechnologies» of the Russian Academy of Sciences;
  • Foundation «Science and Technology Park of Novosibirsk Akademgorodok»;
