AB  - The influence of the hydraulic retention time (HRT) and organic loading rate 
      (OLR) on the performance of the hydrolytic-acidogenic step of a two-stage 
      anaerobic digestion process of sunflower oil cake (SuOC) were assessed. The 
      experiments were performed in laboratory-scale completely stirred tank reactors 
      at mesophilic (35 degrees C) temperature. Six OLR (ranging from 4 to 9 g VS L(-1) 
      d(-1)) for four HRTs (8, 10, 12 and 15 days) were tested to check the effect of 
      each operational variable. Based on the results obtained, it can be concluded 
      that the hydrolysis yields obtained for all HRTs and OLRs assayed were in the 
      range of 20.5-30.1%. In addition, the acidification degree of the substrate was 
      mainly influenced by the OLR but not by the HRTs, the highest value (83.8%) being 
      achieved for an HRT of 10 days and an OLR of 6 g VS L(-1) d(-1).
