Pseudomonas is a widespread bacterial genus embracing a vast number of species. Various genosystematic methods are used to identify Pseudomonas and differentiate these bacteria from species of the same genus and species of other genera. Ability to degrade and produce a whole spectrum of compounds makes these species perspec‐ tive in industrial applications. It also makes possible to use various media, including wastes, for cultivation of Pseudomonas. Pseudomonads may be applied in bioreme‐ diation, production of polymers and low-molecular-weight compounds, biocontrol. Recent studies open up new frontiers for further use of Pseudomonas in various areas.
