Abstract: The invention relates to a separating device for separating a multiphase medium, comprising a cyclone separating device (1) that provokes an at least partial distribution of at least two phases of said medium with the formation of a vortex flow for the medium. The invention is characterized in that each phase, which has a lower density compared to the respective other phase, is separated from said other phase and can be guided out of the separating device by means of a collecting device (35, 37).

Abstract: The present invention relates to specific beta-lactone compounds and compositions thereof for the treatment of infections, such as, e.g., infections with bacteria or infections with protozoa, in particular infections with Gram-positive and/or Gram-negative bacteria and of infectious diseases caused by or related to Gram-positive and/or Gram-negative bacteria, and to the modulation of virulence of Gram-positive and/or Gram-negative bacteria or of protozoa by specific beta-lactone compounds. The invention further relates to the use of the compounds or compositions for preventing or eliminating biofilms.
