有关成龄和幼龄麝鼠性别鉴定的报道屡见不鲜(华树芳,1985,刘桂仁,1984;曲增文,1987,李晓坤,1987),其方法大同小异,我们亦采用其中的“看”和“触摸”法对成龄和幼龄麝鼠进行性别鉴定。但就仔鼠的性别鉴定至今尚未见报道。如能对仔鼠进行性别鉴定,对科研及生产会有重要意义。笔者通过1986 ...

本研究总结了犀牛角仿冒品的研究现状。当前犀牛角的仿冒品主要包括以下几类:洞角、蹄匣、纤维聚合物、真假结合仿品和古犀角等。在这些仿冒品中,洞角的组织特征与犀牛角差别较大,鉴别二者相对容易;蹄匣、纤维聚合物、真假结合仿品和古犀角等特征与犀牛角存在很大的相似性,鉴定时存在一定难度。本研究分别指出了仿冒品与真犀牛角之间的差异或应采取的鉴定方法,将对从事犀牛角鉴定的工作人员提供一些参考。

Actinobacterial Diversity in Depositional Environment of the Southwest India Ocean Ridge and Polyphasic Taxonomy of Five Marine Actinobacteria [PDF]
随着各类拮抗病原菌和顽固性病原菌的出现,以及人们对抗病毒、抗肿瘤等低毒性药物需求的增加,海洋微生物活性次生代谢产物已经成为全球创新药物新的增长点。放线菌是一类重要的药用微生物资源,一百多年来,陆生放线菌资源的研究和开发利用取得了极其辉煌的成就;但受资源获取的限制,目前人们对海洋放线菌的研究还未完全展开。本论文以西南印度洋中脊沉积环境采集的海洋生物样品为基础,对其中的放线菌进行分离方法、生物学特性和系统分类学研究,并结合克隆文库方法对其中放线菌的多样性进行研究;对于发现的新分类单元菌株 ...
