菌草鹿角灵芝新菌株栽培特性及其营养活性成分分析

Analysis of cultivation characteristics and active components of the new strain of antler-shape Ganoderma lucidum with juncao

摘要:

为拓展灵芝栽培原料和应用灵芝新菌株，采用菌草栽培灵芝及其蛋白质、氨基酸、多糖、三萜分析方法，对引进灵芝菌株南GL11进行鹿角灵芝栽培特性研究及营养和有效活性成分分析，结果表明，南GL11与当地主栽培品种韩芝1号进行鹿角灵芝栽培时，灵芝南GL11呈鹿角状，韩芝1号为念珠状，南GL11形状优于韩芝1号.菌草鹿角灵芝南GL11菌柄显著长于韩芝1号，比其长7.4%，菌柄直径略比韩芝1号粗，但无显著差异；鲜芝、干芝产量均显著高于韩芝1号，分别高40.9%、21.4%，其鲜干比分别为2.55、2.18；菌草栽培南GL11鹿角灵芝的多糖、总三萜含量分别比韩芝1号高28.57%、10.2%，差异显著；其粗蛋白与氨基酸含量略低于韩芝1号，但差异不显著，二者氨基酸组分相同，均检出十七种氨基酸，色氨酸则可能因酸分解未能检出.南GL11鹿角栽培时，形状好，产量高，有效活性成分高，具较好的推广前景.

Abstract:

In order to expand the cultivation substrate of Ganoderma lucidum and apply the new strain, the method of cultivating Ganoderma lucidum with juncao and analyzing its protein, amino acid, polysaccharide and triterpene was used. The cultivation characteristics and nutrient and effective active components of introduced Ganoderma lucidum strain Nan-GL11 were analyzed. The results indicated that when Nan-GL11 and HanZhi-1 were cultivated with antlers Ganoderma lucidum, Nan-GL11 was antler like, while the main cultivated variety HanZhi-1 was bead-like, and the shape of Nan-GL11 was superior to HanZhi-1. The stipe of Nan-GL11 was significantly longer than that of Hanzhi-1 by 7.4%. The stipe diameter of Nan-GL11 was slightly thicker than that of Hanzhi-1, but without significant difference. The fresh and dry yield of Nan-GL11 was significantly higher than Hanzhi-1 by 40.9% and 21.4%, respectively. Their fresh-dry ratio was 2.55 and 2.18, respectively. The contents of polysaccharide and total triterpenoid in antler-shape Nan-GL11 cultivated with Juncao were higher than that in Nan-GL11 by 28.57% and 10.2%, respectively, and with a significant difference between them. The contents of crude protein and amino acid in Nan-GL11 was slightly lower than that in Hanzhi-1 but without significant difference, and they had the same amino acid components with 17 kinds of amino acid. Tryptophan was unable to be checked out probably because of the acid decomposition. Because of good shape, high yield and effective active ingredients of the Nan-GL11 antlers when cultivated, antler-shape Nan-GL11 has good prospects for popularization.
