灵芝菌固体发酵三七药渣工艺研究

目的：优化灵芝菌固体发酵三七药渣的发酵工艺，缩短发酵周期，为三七药渣再利用研究提供新的思路。方法运用单因素试验法，以菌蕾形成时间为考察指标，筛选出最佳发酵条件。结果灵芝菌发酵三七药渣最优发酵工艺为：三七药渣粉末（过10目筛），加入1.5％生长因子CaCO3，加适量水（使含水量达60％），接种量（V/V）＝1：1~1.5：1，在（28±1）℃下，避光培养。结论灵芝菌固体发酵三七药渣的工艺稳定、可靠、高效、产物得率高，为三七药渣的进一步研究和开发利用奠定了基础。

Solid-fermentation process of Panax notoginseng residues by Ganoderma Lucidum

Objective To optimize and shorten the fermentation process of Panax notoginseng residues( PNR) by Ganoderma Lucidum as well as provide a new experimental idea for the recycle study of PNR. Methods Single factor experiments were introduced,using the formation time of fungi button as measure index,to screen optimum fer-mentation parameters. Results The optimal fermentation process of PNR by Ganoderma Lucidum was optimized as follow:PNR were smashed into 10 meshes before being mixed with 1. 5%(W/W)CaCO3 as a growth factor;The hu-midity of the mixture was 60%( V/W);Inoculation concentration was 1:1-15:1( V/W);The solid-fermentation of PNR was conducted in dark at the temperature of( 28 ± 1 )℃. Conclusion The optimized fermentation process for PNR was stable,reliable,efficient and highly productive. So these findings would lay a solid foundation for further re-searches and developments of PNR.
