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.

Figure 2: Effect of pH on the mycelial growth of 4 strains of H. erinaceus. Mycelial growth was measured (n = 4) after 10 days of incubation at 25℃ on PDA.

Mentions: The pH values most suitable for the favorable growth of H. erinaceus was observed in the range of 5~9 and the best was pH 6. In the case of IUM3271, similar mycelial growth was observed at pH 6, 7, or 8. The other pH values also showed good mycelial growth, and pH 9 was better than pH 5 for the growth of the different strains of H. erinaceus (Fig. 2). Imtiaj et al. (2008) assayede the pH requirements for the vegetative growth of 10 strains of Schizophyllum commune and reported that pH 5 was the best. A decreased mycelial growth for this strain was found when the pH value was gradually increased to pH 9. Shim et al. (2005) revealed that pH 7 is the most suitable for the optimal growth of M. procera. Shim et al. (2003) shown that the optimal pH of Paecilomyces sinclairii was 8. This result suggested that different species of mushrooms demonstrate optimal mycelial growth at different pH values.
