1999-2003年,在捷克共和国特布盆地生物圈保护区(Tebo Basin Biosphere Reserve)内,我们对13个采矿后形成的人工湖中水鸟群落的形成过程进行了研究。我们假定生活在邻近鱼塘中的水鸟会逐渐向这些人工湖迁移和聚集。在这些人工湖中共记录到42种水鸟,隶属于10个目,其中17种典型的海滨鸟类是该群落的重要组成部分。这些水鸟的季节动态过程与各物种自身的生活史阶段有关(如筑巢、迁徙),同时也被人类的采矿活动所影响。环境因素和人类干扰影响了绿头鸭(Anas platyrhynchos)、疣鼻天鹅(Cygnus olor)和凤头(Podiceps cristatus)等优势种的分布。沙坑湖作为一种独特的生境为本保护区的濒危物种提供了栖息地,如:小苇(Ixobrychus minutus)、大苇莺(Acrocephalus arundinaceus)及其它潜在分布的鸟类。对南波西米亚地区沙坑湖鸟类的研究,可为其它相似地区水鸟群落演替研究提供了重要经验。

N-糖酰胺酶(N-glycosidase,PNGase)是一种糖苷水解酶,主要功能为释放糖肽或糖蛋白上的N-糖链,在食品、生物医药等领域中具有重要的应用价值。目前,商业化的PNGase在使用过程中具有一定的局限性,因此,开发性能优良的新型PNGase具有研究意义。该研究在细菌Dyella caseinilytica中利用编码PNGase的基因,通过在大肠杆菌中进行重组表达,成功获得一种新型PNGase,命名为PNGase Dc,该酶分子质量为63.01 kDa。之后对其酶学特性、功能和应用潜力进行分析。酶学特性结果表明,PNGase Dc的最适pH和温度分别为2.0和37℃,酶促反应无金属离子依赖性;此外,该酶稳定性优良,在4℃下保存45 d仍能维持最高活性;分子对接结果表明,PNGase Dc与底物N′N-二乙酰壳二糖的相互作用力以氢键和范德华力为主;定点突变证明,Asp102和Glu236是影响重组PNGase Dc活性的关键氨基酸;PNGase Dc对标准糖蛋白辣根过氧化物酶和牛乳铁蛋白均具有良好的去糖基化效果;最后,以拟南芥和小鼠血浆作为底物评估PNGase Dc应用潜力,证实PNGase Dc在动植物源糖蛋白的研究中具有一定的应用潜力。综上所述,该研究为动植物源糖蛋白的研究提供了一个新的工具酶PNGase Dc,并为该酶的开发利用奠定理论基础。

灰树花是中国具有较高食药用价值的大型真菌,国内外学界过去多认定其学名为Grifola frondosa。本研究结合形态学和多基因分子系统发育分析,对分离自东亚、欧洲和北美洲的45份样本进行分类研究。多基因联合分析的研究显示了对应各大洲灰树花菌种的高支持率分支,表明不同地域灰树花的遗传信息存在一定程度的差异,分离自我国的灰树花菌种均属于东亚分支,欧洲和北美分支的成员在中国尚未发现分布。因此,东亚分支应代表了一个独立的物种。东亚地区的灰树花过去在日本曾经被描述为白树花***,而且该种曾经被认为是欧洲灰树花***的同物异名,因此,东亚分支的物种学名应该是白树花***。由于中国多数野生和栽培灰树花菌盖颜色较深,故将其命名为白树花的一个新变型*** ***,并指定了该变型的模式标本和菌种(凭证标本HBAU15778,凭证菌株HBAU LM502)。
