Abstract
We clarified optimal culture conditions of Omphalotus japonicus and Neonothopanus sp. mycelia, representative luminous fungi in the temperate and subtropical regions of Japan, respectively. The best growth conditions for the two species were the same; incubation in a medium with 40 g dextrin and 1 g yeast extract per L at pH 5.0 and 30℃ for 14 d. Under these conditions for the best mycelial growth, the luminous intensity of O. japonicus was 5.7 times stronger and that of Neonothopanus sp. was 46.5 times stronger than in potato dextrose broth medium, and the luminous intensity of O. japonicus was 6.6 times stronger and that of Neonothopanus sp. was 3.3 times stronger than on potato dextrose agar medium at pH 5.0 and 30℃ for 14 d.
