Mycelial growth and exo-biopolymer production by submerged culture of various edible mushrooms under different media

초록

Aims: The effect of synthetic media on the submerged mycelial growth and exo-biopolymer production in various edible mushrooms was investigated in shake flask culture. Methods and Results: Among 19 mushrooms examined, the relatively high yield in mycelial biomass and exo-biopolymer production was achieved in potato malt peptone (PMP) medium. In particular, Ganoderma lucidum NO. 1 and Phellinus linteus KCTC 6190 showed favourable growth in PMP medium with exo-biopolymer concentration of 1170 and 1520 mg l-1, respectively. Conclusions: Enhanced exo-biopolymer production was achieved from Ganoderma lucidum NO. 1 and Phellinus linteus KCTC 6190 in a 5L batch fermentor, indicating approximately 5000 and 2410 mg l-1, respectively. Significance and Impact of the Study: The exo-biopolymer production and mycelial growth from various mushrooms were found to be strongly controlled by different complex media.
