Solid-fermentation process of Panax notoginseng residues by Ganoderma Lucidum

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Ca CO3,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。

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 fermentation 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） Ca CO3 as a growth factor; The humidity 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 researches and developments of PNR.
