Nutritional Requirement for Fruit-Body Formation in Favolus Arcularius

Abstract

F. arcularius showed a omnivorous character for the utilization of carbon and nitrogen sources, and was able to fruit well with many carbohydrates and inorganic- or organic-nitrogen sources. Thiamine was required for growth and fruiting, and these processes were promoted by the addition of Ca2+, Mn2+ and Cu2+. The C/N ratio showed a distinct effect on fruiting, and the ratio of about 30:1 was found to be optimal. The primodium formation and growth of sporophores were retarded at a lower C/N ratio. If the nitrogen concentration was fixed, the yield of sporophores was decreased at a higher C/N ratio. The fruiting was not induced only by an optimal nutrient condition, but may be much more highly influenced by light and other physical environments. © 1968, Japan Society for Bioscience, Biotechnology, and Agrochemistry.
