Four polysaccharide fractions were extracted and purified from the cultured stroma of Cordyceps kyushuensis using DEAE-cellulose 23 and Sephadex G-150 column chromatography.
本研究采用硅胶柱、凝胶柱、HPLC等色谱分离技术对紫玉盘内生真菌节菱孢(Arthrinium sp.)A092发酵菌丝体进行分离纯化,通过波谱分析进行结构鉴定;以NCI-H460、SF-268、MCF-7、HepG-2为供试细胞株,采用SRB法对化合物进行细胞毒活性研究.
墓葬遗址中,微生物腐蚀是文物保护工作最普遍的问题之一。本实验旨在对比不同地理距离以及同一地理位置下不同墓葬环境中相似形态菌斑的群落结构。样品分别采自嘉峪关五号墓、太原徐显秀墓、敦煌西晋砖壁画墓以及敦煌汉砖壁画墓,采用Buck Bio-CultureTM Sampler采样器进行壁画附近空气样品采集,使用无菌棉签采集壁画菌斑表层样品,用无菌手术刀进行壁画基层菌斑采集。
Watermelon(Citrullus lanatus) is susceptible to Fusarium oxysporum f.sp.niveum(FON) infection,which causeswilt disease.Arbuscular mycorrhizal fungus(AMF) colonization can alleviate plant disease cause
香菇(Lentinula edodes)是世界著名食用真菌之一,子实体是其重要的食、药用部分。香菇具有典型的伞菌子实体发育过程,对香菇子实体发育过程的研究有助于我们了解大型真菌子实体发育机制。
采用扫描和激光共聚焦显微镜观察,分析了人工栽培梯棱羊肚菌(Morchella importuna)无性孢子的产生过程和细胞核行为变化规律.扫描电镜观察发现,梯棱羊肚菌无性孢子大小均一,无色,球形,无隔,光滑,直径3.5-5.2 μm;分生孢子梗纺锤状或轻微S 形弯曲,(2.1-6.2)×(14.1-18.5)μm,4-6 个瓶颈状环绕着生于菌丝的四周;细胞核染色后显微观察表明,无性孢子多为单核(占
