Laboratory culture of the myxomycetes: formation of fruiting bodies of Didymium bahiense and its plasmodial production of Makaluvamine A.

Laboratory cultures of more than 100 strains of myxomycetes were investigated, and the spore germinations of six strains were observed. The plasmodium of the myxomycete Didymium bahiense was cultured on oatmeal agar plates in a laboratory. The formation of fruiting bodies was observed in a plate culture. From the cultured organisms, a marine sponge metabolite, makaluvamine A (1), was isolated and identified on the basis of spectral data.
