Elicitor-induced β-glucan contents in fruit body of cauliflower mushroom (Sparassis latifolia)

Abstract

Strain KFRI 723 was used for the cultivation of fruit body to promote the production of β-glucan induced by the elicitor using physical stimulation in the superior cultivated fruit body. Three different elicitor treatments on the physical stimulation (UV, temperature, and harvest time) were treated on the primodia of fruit body. Elicitor controlled by UV light has an effect on the change of the β-glucan contents in flabellae and stipe of cauliflower mushroom, both parts have the highest concentration of β-glucan in strains irradiated by UV for 10 min: 41.36 ± 2.96% of flabellae and 42.16 ± 2.90% of stipe. Both flabellae and stipe represented β-glucan contents in order of low (10 ± 1 °C) - mid (21 ± 1 °C; control) - high temperature (25 ± 1 °C). In the different harvest time, the β-glucan contents of flabellae and stipe show high contents at 21st and 26th day and decreased since 31st day of harvesting.
