Outline
Buchwaldoboletus xylophilus is the second cultivatable species of Boletales with significant scientific and commercial potential value. To better develop and utilize this wild resource, the morphological and molecular identification and the biological characteristic investigation of a wild strain, JSJ-Bx1, were carried out. The results show that this wild strain belongs to B. xylophilus. The hyphae grow well under the temperature of 35℃ and pH 4.0 on the medium using glucose as carbon source, and yeast extract as nitrogen source with the addition of inorganic salt FeSO4. The optimal medium formula consists of 20 g glucose, 2 g yeast extract, 1.5 g FeSO4, 0.3 g 1/2 MS medium, 20 g agar, and 1 L water. The hypha growth rate is 11.38 mm/d. The optimal expanded cultivation substrate formula consists of 20% sawdust, 30% cottonseed hulls, 20% wheat grains, 10% corn flour, 10% red soil, 8% bran, 1% gypsum powder, 1% glucose, 0.1% KH2SO4, and 0.1% FeSO4. The mycelial colonization period is about 20 days; primordial formation takes about 5 days, and the growth and maturation of the fruiting bodies takes about 7 days. The average yield is 96.64 g/bottle and the biological efficiency is 31.58%.
