Key points

  • Exo-polymer (EP) was produced at 1.2 g l(-1) in submerged culture of Auricular auricula-judae
  • Crude EP (AJ-0) has 70% anti-complementary activity (inhibition of total complementary hemolysis 50%; ITCH50)
  • The activating pathway of the complement system occurred through both the classical and alternative pathways, though the major pathway was the classical one
  • Fractionation of AJ-0 using Sepharose CL-6B gel chromatography gave three major fractions (AJ-Fr-I, II and III) of which the first was the most active
  • The mycelial growth and EP production of A. auricula-judae were optimal at pH 6, 25 degrees C and pH 5, 25 degrees C, respectively
