This study showed that higher dry weight biomass of P. pulmonarius produced in BRMY medium of 11.72 ± 5.26 g L−1 at 3 days was achieved compared to work done by Kim et al. (2002) where dry biomass of P. sajor-caju grown in an automated 5 L-bioreactor was estimated at 1.08 g L−1 in mushroom complete medium consisting of 2.64 g L−1 in yeast malt extract, and 2.84 g L−1 in potato malt peptone media, respectively, in 5 days. Further, higher biomass dry weight was also obtained in our study compared to previous study done by Confortin et al. (2008).
