Liquid fermentation conditions of various Ganoderma lucidun strains

Optimum conditions of liquid fermentations of six strains of Ganoderma lucidun were determined basing on single factor experiments in shaking flasks.It showed that medium I is suitable for 3 strains as G9,moutant tai and 444 under 28℃shaked at 80 r/min,Under the conditions,dry mycelium weight was 0.7635 g/100 ml,1.0124 g/100 ml and 0.5635 g/100 ml,respectively.For strain 44,dry mycelium weight was 0.5197 g/100 ml in medium I at 24℃shaked for 120 r/min.And for strain 265,dry mycelium weight of was 0.9954 g/100 ml in medium I at 28℃shaked for 160 r/min.Dry mycelium weight of strain 267 was 0.9302 g/100ml in medium IV at 28℃shaked for 160 r/min,Optimum conditions for production of crude exo-polysaccharide were different from that for mycelium.
