The use of mushroom hydrolysate from waste bag-log as the nitrogen source to mycelium biomass and exopolysaccharide production in Pleurotus eryngii cultivation

In this study, Pleurotus eryngii head part waste in a bag-log was collected and processed to yield mushroom hydrolysate powder (MHP). To test its stimulatory effect, a P. eryngii submerged culture was conducted. The prepared MHP (1.6%) and glucose (2%) were found to be the best sources for both mycelial biomass and EPS productions. A specific growth rate of 0.68 day−1, and a specific EPS yield of 9.55 g/g-dry-cell-weight were obtained under...
