Influence of culture conditions on mycelial growth and luminescence of Panellus stipticus (bull.) P. Karst
Abstract
Panellus stipticus (Bull.) P. Karst, a naturally bioluminescent tropical fungus, has been studied in vitro for the optimum culture conditions viz culture media, temperature, pH and days of incubation required for luminescence. Temperature and pH affect growth and bioluminescence to a great extent. Glucose-peptone medium has been found to be the best for optimum mycelial growth as well as luminescence. The fungus exhibits luminescence at 20-24°C. The maximum mycelia dry weight (mg/25ml of the basal media) and luminescence observed at pH 4.0. The fungus exhibits luminescence after eight days of incubation at 24°C and pH 4.0, whereas it intensified to maximum after 13 days of incubation (pH 4.0 and temperature 24°C)
