AB  - The aim of this study was to couple biochemical and molecular methodologies for 
      evaluating the impact of two recycling technologies (composting and 
      vermicomposting) on a toxic organic waste. To do this, six enzyme activities 
      controlling the key metabolic pathways of the breakdown of organic matter, 
      real-time PCR assays targeting 16S rRNA genes, and denaturing gradient gel 
      electrophoresis (DGGE) profiling-sequence analysis of PCR-amplified 16S rRNA 
      fragments have been used to determine the functional diversity, bacterial number, 
      and bacterial community structure, respectively, in a mixture of olive waste and 
      sheep manure, and in the derived compost and vermicompost. Both the recycling 
      technologies were effective in activating the microbial parameters of the toxic 
      waste, the vermicomposting being the best process to produce greater bacterial 
      diversity, greater bacterial numbers and greater functional diversity. Although 
      several identical populations were detected in the processed and non-processed 
      materials, each technology modified the original microbial communities of the 
      waste in a diverse way, indicating the different roles of each one in the 
      bacterial selection.
