This study was carried out to evaluate the radical scavenging activityof giycoprotein isolated from jellyfish Rhopilema esculentum,and the effect on which of temperature.The results showed glycoprotein had dose-dependent scavenging activities for superoxide anion radical and hydroxyl radical.The value IC50 of glycoprotein was 450μg·ml-1 while value IC5o of carnosine was 80μg·ml-1 for scavenging activities of superoxide anion radical,and the value IC50 of glycoprotein was 750μg·ml-1 while value IC5o of carnosine was 100μg.ml-1 for scavenging activities of hydroxyl radical.That suggest that the glycoprotein has strong radical scavenging activity but lower than camosine.Moreover,radical scavenging activity was stable at high temperature.

定置网具是一种被动过滤性渔具,其渔获效果往往受水流、底质以及季节等因素的影响.为了改进传统的定置网具,本试验参考定置张网、多门网箱簖以及底层鱼诱捕定置网箱等定置网中拦网、八字门的设计参数,结合本次试验条件设计了由拦网、八字门组成的模拟组合网,研究了鲤、草鱼在400 Hz矩形波连续音的刺激下对该模拟组合网的行为反应,探讨了音响驯化技术与定置网具相结合的联合渔法中拦网、八字门的相关参数以及开发新渔具渔
甲烷水合物的溶解与分解过程是甲烷水合物成藏机制的关键科学问题,同时也是造成环境灾害事件的重要因素.近年来,在阅读甲烷水合物相关文献中发现有些作者对甲烷水合物溶解和分解的复杂动力学过程产生了一些混淆,从而对甲烷水合物的成藏机理及其对环境气候变化作用的认识造成偏差.本文基于大量的研究成果,并结合作者多年对甲烷水合物形成与分解动力学过程的系统研究,认为海底存在一种甲烷气体的动态存储与排泄平衡,甲烷水合物
乌-夏地区稠油主要分布在风城油田,正构烷烃和无环类异戊二烯烷烃严重降解,胡萝卜烷缺失,藿烷含量部分降解或严重降解,甾烷和重排甾烷部分降解,而三环萜烷含量、孕甾烷和升孕甾烷含量很高,Ts/Tm平均值为3.55.根据稠油的正构、异构烷烃降解程度、生物标记化合物和25-降(藿)烷系列化合物的降解程度以及三环萜烷含量和孕甾烷含量,将乌-夏地区稠油生物降解作用级别划分为6级.根据构造演化特征并结合油气水分布

应用AFLP技术对我国条斑星鲽引进群体(烟台、大连和莱州)共63尾个体的遗传多样性及遗传变异进行分析,计算了3个群体间的遗传相似性指数和遗传距离,并构建了UPGMA系统发生树.10个引物组合在3个群体中共扩增到827个位点,大小位于50～700bp之间.每个引物组合扩增到的多态性条带在8到37条之间不等,平均为17.9个.3个群体的多态性位点比例分别为29.14％、15.60％和 20.31％;S
海洋嗜杀酵母YF07b的嗜杀因子经Sephadex G75凝胶过滤和DEAE-Sephorose Fast Flow阴离子交换得到纯化,经SDS-PAGE检测得到分子量为47kDa的单一条带.纯化后的嗜杀因子有β-1,3-葡聚糖酶活性,并且纯化后的嗜杀因子仍具有抑菌活性.根据陆地嗜杀酵母Pichia anomala strain K的嗜杀因子(β-1,3-葡聚糖酶)的基因及相关序列设计引物克隆菌株
建立了微波消解-电感耦合等离子体质谱(ICP-MS)测定富硒及无富硒海带中硒元素含量的方法,采用In元素为内标,利用其回收率对测定结果进行校正.该方法对硒元素的检出限为0.143μ g/L,In元素加标回收率为86.7％～114.5％,说明该方法灵敏度高,结果准确可信.将富硒海带叶状体经人为划分为上部、中部及下部,通过测定海带三个不同部位的总硒含量(干重)分别为2260.5ppm,2287.5pp
