为确定引起枸杞霉变的菌种类型，该文以采后鲜枸杞果实为材料，分离导致其霉变的菌种，经形态学特征及分子生物学特征鉴定确定类型，并对与其霉变速率相关的部分生物学特性进行研究。结果表明：从霉变的鲜枸杞中共分离出6株致霉菌，分别鉴定为：菌种1为镰刀菌、菌种2为交链孢霉、菌种6为尖孢镰刀菌、菌种7为青霉菌、菌种11为串珠状赤霉菌及菌种21为草酸青霉。经过回接试验发现6种霉菌均能使健康枸杞鲜果霉变，从这些病斑中...
旨在了解梅花鹿鹿茸不同部位蛋白表达差异，本研究以腊片部位、血片部位和骨片部位的梅花鹿鹿茸组织为试验材料，运用双向电泳（2-DE）和MALDI-TOF-TOF串联质谱技术对不同部位梅花鹿鹿茸差异表达蛋白质进行鉴定，并对差异蛋白进行生物信息学分析。结果表明，成功筛选出37个差异表达蛋白，主要涉及多细胞生物体发生、解毒、细胞成分组织或生物发生、细胞聚集、定位、对刺激的反应、生物黏附、发育、单一生物体发生...
