title: [Ability of opportunistic enterobacteria to adapt to different temperatures].
abstract: OBJECTIVE
  To study variability of enzymatic apparatus of opportunistic enterobacteria.
  
  
  METHODS
  Clinical strains of Morganella morganii, Citrobacter freundii, Proteus mirabilis isolated from patients treated in Irkutsk Regional Hospital for Infectious Diseases. Activity of cellulase and lipase as well as amount of auxins and gibberellins was studied in these bacteria at different cultivation temperatures.
  
  
  RESULTS
  It was shown that studied species isolated from humans enterobacteria are able to produce plant growth regulators amount of which depends from cultivation temperature and type of microorganism. Activity of cellulase sharply rises if temperature falls.
  
  
  CONCLUSIONS
  Obtained results show high adaptation potential of opportunistic bacteria from Enterobacteriaceae family. Switch on saprophytic mechanism after fall of temperature to environment-corresponding values allows them to survive in soil and arrange different interactions with soil biota including plants.
