The use of additives as the stimulator on mycelial biomass and exopolysaccharide productions in submerged culture of Grifola umbellata

In this study, various additives including organic acids, alcohols, vegetable oils, surfactants and polymers were added in the cultural medium to investigate their stimulatory effects on Grifola umbellate mycelia growth and exopolysaccharide (EPS) production. It was found that the commonly used stimulatory additives, effective in other mushrooms’ cultures, exhibited negative results in Grifola umbellata submerged culture. In contrast, the...
