Response surface methodology-based optimization of <i>Inonotus hispidus</i>' liquid fermentation medium and evaluation of its exopolysaccharide activities.

3.1.2 The impacts of nitrogen sources on the mycelial biomass of Inonotus hispidus As shown in Figures 2A , B , it is very easy to conclude that the effects of yeast extract, peptone, and beef extract on promoting growth are highly significant; when yeast extract is used, the biomass levels of MS-5 and MS-9 are 9.27 g/L and 9.17 g/L, respectively, which are more than 1.29–1.86 times those of the control group (CK), while the roles of four nitrogen sources, i.e., ammonium tartrate, ammonium sulfate, ammonium nitrate, and urea, in promoting the growth of Inonotus hispidus ’ mycelial biomass are not significant enough.
