Bottom Line: With the exception of lactose, most of the carbon sources assayed demonstrated favorable vegetative growth of H. erinaceus.For mycelial growth, the most suitable nitrogen source was alanine and the most unsuitable was histidine.Oak sawdust medium supplemented with 10~20% rice bran was the best for mycelial growth of the mushroom.

ABSTRACT
Vegetative growth of four different strains of Hericium erinaceus was observed. The temperature suitable for optimal mycelial growth was determined to be 25℃, with growth observed in the extend temperature range of 20~30℃. The different strains of this mushroom showed distinct pH requirements for their optimum vegetative growth, with the most favorable growth observed at pH 6. Considering vegetative mycelial growth, PDA, YM, Hennerberg, Hamada, and Glucose peptone were the most favorable media, and Czapek Dox, Hoppkins, Glucose tryptone, and Lilly were the most unfavorable media for these mushroom strains. With the exception of lactose, most of the carbon sources assayed demonstrated favorable vegetative growth of H. erinaceus. For mycelial growth, the most suitable nitrogen source was alanine and the most unsuitable was histidine. Oak sawdust medium supplemented with 10~20% rice bran was the best for mycelial growth of the mushroom.

Effect of carbon source on the mycelial growth of 4 strains of H. erinaceus. Mycelial growth was measured (n = 4) after 10 days of incubation at 25℃ on basal medium. Dex: Dextrin, Fr: Fructose, Ga: Galactose, Gl: Glucose, Lac: Lactose, Mal: Maltose, Man: Mannose, Sor: Sorbitol, Suc: Sucrose, and Xy: Xylose. Each carbon source was added to the basal medium at the concentration of 0.1 M.

Figure 4: Effect of carbon source on the mycelial growth of 4 strains of H. erinaceus. Mycelial growth was measured (n = 4) after 10 days of incubation at 25℃ on basal medium. Dex: Dextrin, Fr: Fructose, Ga: Galactose, Gl: Glucose, Lac: Lactose, Mal: Maltose, Man: Mannose, Sor: Sorbitol, Suc: Sucrose, and Xy: Xylose. Each carbon source was added to the basal medium at the concentration of 0.1 M.

Mentions: Ten different carbon sources were assayed for optimal culture conditions. The mycelial growth of the strains used was best and mostly similar on dextrose, fructose, or glucose. Lactose showed very slow vegetative growth for all 4 strains (Fig. 4). Shim et al. (1997) assayed the effect of 19 carbon sources on the mycelial growth of G. umbellata and reported that growth was favorable on any carbon source used except salicin, cellobiose, and lactose. Shim et al. (2003) also found that dextrin was suitable for mycelial growth of P. fumosoroseus, which is equivalent to our findings.
