AB  - The purpose of this study was to investigate hydrolysis of animal fleshing 
      (ANFL), a predominant tannery solid waste and to characterize the acetogenic 
      fermentation products of anaerobic digestion. The acidogenic digestibility of the 
      tannery solid wastes were evaluated up to 120 h using batch anaerobic digestion 
      tests performed under mesophilic condition at 37 degrees C. The degradation of 
      ANFL starts with non-fibrillar proteins and proceeds with fibrillar proteins. The 
      release of aliphatic amino acid in the early stages of hydrolysis (24 h) and 
      followed by aromatic amino acids (24-72 h) were evidenced by HPLC analysis. The 
      maximum production of propionic and valeric acid were observed in 72 h followed 
      by rapid increase in acetic acid in 96 h using GC-MS. Breakdown of ANFL and 
      formations of other metabolites were evidenced by FT-IR and (1)H-NMR 
      spectroscopy.
