ARTP Mutagenesis to Improve Mycelial Polysaccharide Production of Grifola frondosa Using a Mixture of Wheat Bran and Rice Bran as Substrate

Figure 3

Five generations of fermentation of the parent strain and three mutant strains (GFA1, GFA2, GFA7) during bioconversion of wheat bran and rice bran at 23°C and 150 r/min. The mycelial biomass concentration in five generations (a), the mycelial polysaccharides concentration in five generations (b), the average mycelial biomass and mycelial polysaccharides of five generations (c), the weight-for-weight yields of mycelial polysaccharides (d). The mycelial biomass was calculated as the dry weight of mycelia. Each data point is the mean of three replicate samples. (a) and (b) indicate significant difference at in average five generations.
