Abstract ▼ AI-Helper

Mushroom strains of Polyporales from the genera Coriolus, Trametes, Pycnoporus, Ganoderma, and Formitella were explored in terms of mycelial growth characteristics for the application of mushroom mycelia as alternative sources of materials replacing fossil fuel-based materials. Among the 64 strains of Polyporales, G. lucidum LBS5496GL was selected as the best candidate because it showed fast mycelial growth with high mycelial strength in both the sawdust-based solid medium and the potato dextrose liquid plate medium. Some of the Polyporales in this study have shown good mycelial growth, however, they mostly formed mycelial mat of weak physical strength. The higher physical strength of mycelial mat by G. lucidum LBS5496GL was attributed to its thick hyphae with the diameter of 13 mm as revealed by scanning electron microscopic analysis whereas the hyphae of others exhibited less than 2 mm. Glycerol and skim milk supported the best mycelial growth of LBS5496GL as a carbon and a nitrogen source, respectively.

그림 Figure 2. Scanning electron microscopy analyses of mycelial mats from different polypore mushrooms in two different magnifications (×250 and ×900). (A,B) Coriolus brevis LBS1894CB. (C,D) Fomitella fraxinea LBS4388FF. (E,F) Ganoderma lucidum LBS5496GL. (G,H) F. fraxinea LBS2351FF. (I,J) C. versicolor LBSCVEYCV. (K,L) F. fraxinea LBS2349FF. The samples were prepared using the mycelial mats obtained from the PDB plate medium culture. Arrows indicate the hyphal diameters of the mycelium in the mycelial mat. The hyphal diameter of F. fraxinea was less than 1 μm, as indicated.
그림 Figure 3. Effects of carbon and nitrogen sources on the mycelial growth of Ganoderma lucidum LBS5496GL. (A) Effect of carbon sources. Two different concentrations (4 and 10 g/L) of different carbon sources were examined in minimal medium. (B) Effect of nitrogen sources. 5 g/L of each nitrogen source was examined in minimal medium. (C) Effect of the concentrations of skim milk. All the experiments were triplicated. The error bars indicate standard errors of each experimental sets. (D) Mycelial mat generated from scale-up experiment using the optimal conditions.
