Abstract: The effects of saponified fatty acids with different saturations on mycelial growth of Lentinula edode (Berk.) Pegler were observed by plate culture method in this study. Results showed that saturated fatty acid can accelerate the mycelium growth of Lentinula edode (Berk.) Pegler, namely having a horizontal impetus on the mycelium growth. Unsaturated fatty acid can increase the amounts of branches of mycelium to make the colony denser, namely promoting vertically on the mycelium growth. The mixture of monounsaturated fatty acid and saturated fatty acid not only can promote cross growth of the mycelium, but also increase the density of colony.

Key words: fatty acid, saturation, saponification, Lentinula edode (Berk.) Pegler, growth of mycelium
