Main achievements

Laboratory of Biotechnology of Physiologically Active Compounds

Since 2012 the lab successfully completed nine projects on the development of methods for the biosynthesis, separation, and purification of various pharmaceutical substances (the total cost of the projects exceeded 30 mln. RUR) including:

  • Development of optimal schemes of the multi-stage induced mutagenesis to obtain highly-productive strains of fungi, actinomycetes, and bacteria;
  • Obtaining of highly productive mutant strains from wild strains for the industrial production of such substances as compactin and polymyxin B, and the development of corresponding technologies for the separation and purification of these compounds;
  • Development of a strain able to produce rifamycin B using a new substrate, diethylmalonic acid monoureide;
  • Development of laboratory and industrial regulations for the biosynthesis of tobramycin and josamycin pharmaceutical substances and the quality control methods for their production;
