以药食两用中药为基质的灵芝发酵

Study on Submerged Fermentation of Ganoderma lucidum into Chinese Pharmaceatical Edible Prodct

本文研究了以药食两用中药为基质的灵芝发酵,并用响应面分析法对培养基进行了优化,结果表明:山药、芡实适合于作碳源,莲子、薏苡仁适合于作氮源;以山药、薏苡仁为基质的最佳发酵培养基为:葡萄糖2.1%,山药3%,薏苡仁1.96%,灵芝菌体生物量可达2.05g/100ml。

The production of Ganoderma lucidum into Chinese pharmaceutical-edible product has been studied by submergedfermentation.The cultural medium has also been optimised by response surface methodology(RSM).The results showed:Dioscorea opposita and Euryale ferox were good carbon sources, Nelumbo nucifera and Coix lachryma-jobi were good nitrogensources.The optimised cultural medium was glucose 2.1%,Dioscorea opposita 3%,and soix lachryma-jobi 1.96%,and the dryweight of mycelia reached 2.05g/100ml.
