以40个灵芝属菌株（包括9个江西野生菌株和31个国内栽培菌株）为试验材料，对其菌丝特征、子实体产量及农艺性状进行了评价。结果表明，不同菌株的菌丝特征存在一定差异，其中菌株G23、G06、G17、G15的菌丝平均生长速率较快，长势较好。不同菌株子实体产量、生物学效率，以及菌盖大小、形状、菌柄长度、直径等农艺性状差异较大。野生菌株G01、G06和G09具有较大的驯化潜力，可进一步开发利用，栽培菌株G33、G32、G11、G12、G30综合表现优异，适宜在江西省示范推广。 相似文献

对从广州微生物研究所引进9个草菇菌株与江苏省江南生物科技有限公司常用品种V830进行对比试验,以期能筛选出适合江苏省丹阳市及周边地区栽培出菇的优良菌株.经过对菌丝生长速度、生物学效率及出菇农艺性状进行的分析比较,结果表明,在这10个供试菌株中,草菇菌株V9715具有菌丝生长旺盛,出菇时间早,抗杂菌能力强,生物学效率高,子实体商品性状较好的特点,而且所有的试验都是在当地自然条件下栽培,其产量和形状表现为适宜在江苏省丹阳市及周边地区生产中应用,可代替本地菌株V830使用,同时为遗传变异和遗传育种提供了重要的材料. 相似文献

2种灵芝液体培养的比较研究 总被引：1，自引：0，他引：1
比较赤芝和松杉灵芝液体培养菌丝体生物量和多糖含量。在相同的培养条件下,对赤芝和松杉灵芝进行液体培养,采用热水浸提法提取干燥菌丝体多糖,通过蒽酮-硫酸法测定赤芝和松杉灵芝多糖含量。测得赤芝多糖含量为7.22%,松杉灵芝多糖含量为3.78%,液体培养赤芝生长速度比松杉灵芝快,多糖含量也比松杉灵芝高,因此,赤芝更适合用于液体培养生产灵芝多糖。 相似文献

AIM: To investigate the effect of Ganoderma lucidum spores powder on the expression of insulin-like growth factor-1 (IGF-1), nuclear factor-κB (NF-κB) and apoptosis of nerve cells in rats with epilepsy established by pentetrazole. METHODS: The sub-eclampsia dosage of pentetrazole (PTZ) was used to make epilepsy model. Ganoderma lucidum spores powder group was given from stomach. The enduring time and latent period were recorded. The immune reactivity of IGF-1, NF-κB/P65 and apoptosis of nerve cells were measured with immunohistochemical staining and TUNEL method. RESULTS: In high power sight (×400), there were much more apoptosis cells in hippocampus and brain cortex of model group (18.80±2.13, 16.87±2.00) than those in control group (0.97±0.52, 0.58±0.25). The expressions of IGF-1, NF-κB in model group were higher than those in control group. Compared with model group, the latent period of Ganoderma lucidum spores powder group at the 17th, 21th, 25th days were longer (P<0.05, P<0.05, P<0.01, respectively).There were less apoptosis cells in hippocampus and brain cortex of Ganoderma lucidum spores powder group (12.30±2.46, 10.48±1.33) than those in model group. The expression of NF-κB/P65 in Ganoderma lucidum spores powder group was lower than that in model group, but the immune reactivity of IGF-1 increased more distinctly in Ganoderma lucidum spores powder group than that in model group. CONCLUSION: IGF-1, NF-κB and apoptosis of nerve cells may have play a role in occurrence and development of PTZ-induced epilepsy. Ganoderma lucidum spores powder can suppress expression of NF-κB strongly, and facilitate the immune reactivity of IGF-1, which may be one of the mechanisms by which Ganoderma lucidum spores powder restrains the apoptosis of nerve cells caused by epilepsy to prevent the damages of nerve cells. 相似文献

测定灵芝提取液中杂质含量对灵芝品质具有重要意义。采用微波消解方法对灵芝提取液样品进行测定前预处理,同结合二值化方法对样品溶液图像进行阈值分割,选取适当的小波函数,提取样品溶液图像的局部灰度突变点,对灵芝提取液中金属杂质的边缘定位;在此基础之上,通过ICP-MS测定灵芝提取液中的Pb、As、Hg等金属杂质含量,实现对灵芝提取液中杂质含量的精确测定。试验结果表明,与传统测定方法相比,所提方法具有测定速度快、误差率低的优点。 相似文献
