摘要
对金福菇出发菌株采用氮离子束进行诱变,通过低温筛选出5个菌株,测定诱变后各菌株的出菇产量、生物学效率和总糖、蛋白质、粗脂肪、粗纤维等营养成分以及降血脂成分洛伐他汀含量,筛选出营养和保健价值较高的优质突变菌株。结果表明,金福菇诱变菌株JF-004的生物学效率最高达到76.64%,其每栽培袋平均产量为(191.60±1.80)g。诱变菌株JF-004的蛋白质和粗纤维含量最高,分别达到35.26%和9.26%,具有适中的总糖含量和较低粗脂肪含量,符合低脂肪、高纤维的膳食结构;同时JF-004的洛伐他汀含量在所有菌株中也达到最高,子实体中含量为(10.180±0.123)μg·g-1,是一株营养和保健价值较高的优质诱变菌株。
Tricholoma lobayensc heim fruit body was injected by ion beam to induce mutant strains. After treatment, the fruiting yield and biological efficiency of the strains were investigated. As results, a high quality mutant strain was screened out by determining the contents of conventional nutrients including the total sugar, protein, crude fat, crude fiber, and lovastatin（a hypolipidemic component）. The results showed that the mutant strain JF-004 had the highest yield（191.60±1.80） g, biological efficiency（76.64%）, protein content（35.26%）, and crude fiber（9.26%）, a moderate total suger, and a low crude fat content, which fits the low-fat and high-fiber dietary pattern and is beneficial to human health. The mutant strain JF-004 also had the highest lovastatin content（10.180 μg·g^-1） in the sporocarp. The results indicated that JF-004 is a high-quality mutant strain.
