The present invention provides to a process for recovery of an organic compound (i.e. Ethanol, propanol, butanol, Acetone, iso-propyl alcohol) from a fermented broth which is produced from different fermentation technologies. The present invention particularly relates to an integrated process for ethanol separation from the fermentation broth using integrated vapor compressing unit (turbofans), evaporator (falling film) and a broth stripper column (vacuum distillation system). The process is operated under low temperature for the separation and recovery of the organic compound (particularly ethanol) from the fermented broth containing live microbes typically below or at 50&#xb0; C. to ensure the activity of the microbes in the broth recycle. Again, the activity of the microbes is further ensured by maintaining the residence time of the microbe containing broth outside the Fermentor is less than or equal to 10 minutes.
