Abstract
|
|
|
|
The anti-complementary activity (immunostimulating activity) was tested for the exo-polymers (extra-cellular polymer) produced from submerged mycelial cultures of 21 types of higher fungi. Anti-complementary activity of the exo-polymer from Cordyceps militaris showed the highest (69.0%) followed by Pleurotus ostreatus (63.7%) and Trametes suaveolens (61.4%). The mycelial growth rate and biomass doubling time of C. militaris in a 5 l air-lift fermenter were 0.0255 h^-1 and 27.2 h, respectively. The yield of the exo-polymer produced from the culture broth of C. militaris was 2.95 ㎎ of dry weight/㎖ of culture broth. Sugar and amino acid compositions of this exo-polymer were analyzed.
