Abstract:
The better conditions for flask fermentation of Grifola frondosa are:QF medium.25℃.pH4 5 filled volume 60mL/500mL flask.rotated speed 100rpm.When 0 4%CMC is added to medium,the growing point of mycelia can increase and the biomass is rised.Scale\|up test has done in 10 litre airlift bioreactor.The rate of biotransformation between biomass and original sugar or between biomass and consuming sugar is over 24% or up to 435%.In mycelium the polysaccharide content is 10 2%.In culture fluid the polysaccharide content is 1 38%.
