AB  - Sunflower oil cake (SuOC) is the solid by-product from the sunflower oil 
      extraction process and an important pollutant waste because of its high organic 
      content. For the anaerobic digestion of SuOC three different industrial reactors 
      were compared as inoculum sources. This was done using a biochemical methane 
      production (BMP) test. Inoculum I was a granular biomass from an industrial 
      reactor treating soft-drink wastewaters. Inoculum II was a flocculent biomass 
      from a full-scale reactor treating biosolids generated in an urban wastewater 
      treatment plant. Inoculum III was a granular biomass from an industrial reactor 
      treating brewery wastes. The highest kinetic constant for methane production was 
      achieved using inoculum II. The inoculum sources were analyzed through PCR 
      amplification of 16S rRNA genes and fingerprinting before (t = 0) and after the 
      BMP test (t = 12 days). No significant differences were found in the bacterial 
      community fingerprints between the beginning and the end of the experiments. The 
      bacterial and archaeal communities of inoculum II were further analyzed. The main 
      bacteria found in this inoculum belong to Alphaproteobacteria and Chloroflexi. Of 
      the Archaea detected, Methanomicrobiales and Methanosarcinales made up 
      practically the whole archaeal community. The results showed the importance of 
      selecting an appropriate inoculum in short term processes due to the fact that 
      the major microbial constituents in the initial consortia remained stable 
      throughout anaerobic digestion.
