AB  - Due to the chemical and physical structure of a lignocellulosic biomass, its 
      anaerobic digestion (AD) is a slow and difficult process. In this paper, the 
      results obtained from a batch biochemical methane potential (BMP) test and 
      fed-batch mesophilic AD assays of sunflower oil cake (SuOC) are presented. Taking 
      into account the low digestibility shown during one-stage experiments the methane 
      yield decreased considerably after increasing the organic loading rate (OLR) from 
      2 to 3 g VS L(-1) d(-1), SuOC was subjected to a two-stage AD process 
      (hydrolytic-acidogenic and methanogenic stages), in two separate reactors 
      operating in series where the methanogenic stage became acidified (with >1,600 mg 
      acetic acid L(-1)) at an OLR as low as 2 g VS L(-1) d(-1). More recently, BMP 
      assays were carried out after mechanical, thermal, and ultrasonic pre-treatments 
      to determine the best option on the basis of the methane yield obtained.
