Abstract

|
|
This study was designed to develop functional drink from jujube extract through a simple submerged culture of three basidiomycetes species. The optimum Brix and pH of the jujube extract for culturing the Ganoderma lucidum appeared to be 5 Brix and pH 4. Ten days of culture period produced maximum mycelium. The optimum Brix and pH of the jujube extract for culturing the Coriolus versicotor appeared to be 5 Brix and pH 5. Ten days of culture period produced maximum mycelium. The optimum Brix and pH of the jujube extract for culturing the Phellinus igniarius appeared to be 3 Brix and pH 5. For the maximum mycelial production eighteen days of culture period was required for Phellinus igniarius. The antitumor activity of the polysaccharides extracted from the fermented drinks was demonstrated through the tumor cell line experiments. The IC_(50) values of the jujube drinks fermented with Ganoderma lucidum and Phellinus igniarius against stomach cancer cell line appeared to be one fourth that of the jujube drink which was not fermented with basidiomycetes.
