• Recognition of biotechnological potential of methanotrophs isolated from various ecosystems (inc. surface and deep biosphere).
  • Natural microbial diversity and its biotechnological application
  • Production of ectoine and other osmolytes in methylotrophic bacteria. Perspective of application of biosynthesis of the bioactive substances in medicine, pharmacy and cosmetology and food production and conservation industry
  • Use of autochthonic microbial communities for bioconversion of fossil coals at different stages of maturity (beginning from peat and lignite to hardcoal) to methane and other organic compounds, being potentially useful as fertilizers (humic and fulvic. acids).
  • Redox processes in water and soil, nutrient transformation and its availability, soil buffering capacity, enzymatic activity and remediation of heavy metals from environments at different stages of pollution.
  • Oxygenology as a new scientific discipline related to the presence and role of oxygen in nature on Earth, comprising issues of storage, transport, generation, adsorption, turnover, functions and measurements in the environment in respect to essential role in the life of all macro- and microorganisms as a dominant final acceptor of electrons
  • Investigation on biotechnological, nonconventional methods of energy attaining.



  1. Means of ectoin production (P.395782) (Z. Stępniewska, A.Kuźniar, A. Pytlak)
  2. Means of polyhydroxyalkanoates production from methane by the methanotrophic consortium inhabiting coalbed rocks (P.401711) (Z. Stępniewska, A. Pytlak, A.Kuźniar).
  3. Bioconversion of coal to methane from materiale at different stages of coalification with the use of microbial consortium (Z. Stępniewska, A. Szafranek-Nakonieczna)
