, 2003 铁、锰离子或铁、锰氧化物可作为电子供体或受体被微生物催化氧化或还原,这种微生物催化作用是自然界金属循环、矿物形成与迁移的重要推动力。微生物的呼吸作用或特异性酶使铁、锰氧化沉淀或还原浸出,同时其它有价金属共沉淀或浸出,所以铁、锰及其氧化物的微生物循环转化作用是资源环境领域生物技术的重要的共性基础。基于对微生物催化铁、锰氧化还原过程的机理探索,对自然界固有的缓慢生物过程进行人工强化提取富集有价金属、消除环境金属污染 ...

对中国科学院千烟洲试验区人工林的养分生物循环进行了研究。结果表明 ,湿地松和马尾松人工林中的N、P和K养分元素积累量分别占 7种元素积累量的 41 .8%和 46.6%。而木荷林只占 2 2 .9% ,说明了湿地松和马尾松人工林生产lt干物质生物量要比木荷人工林消耗更多的N、P和K养分元素。通过降雨淋溶归还给 3个林分的 7种养分元素量 ,分别为相应林分凋落物中的养分元素归还量的 0 .2 9倍、0 .2 0倍、0 .1 5倍。按林分生物循环特点可把该试验区的人工林划分为 :湿地松林和马尾松林为高存留 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 1990 高催乳素血症可致卵巢功能紊乱,并导致不孕。然而,近年国外有若干报道少数本症伴存正常排卵周期与生育功能,引起人们注意。其循环中催乳素以生物活性较低的多聚型‘大’与‘大大’分子催乳素占主要成份,有人称作假高催乳素血症。通常使用胶层析方法检测到这类妇女循环中过量的多聚型‘大’与‘大大’分子催乳素成份。本文报告2例不孕妇女有高催乳素血症伴正常排卵周期。催乳素水平分别为133～165ng/ml和115～136ng/ml。胶层析结果显示其循环中‘大大’分子催乳素分别占83％及87％。例1同时合并有5.3× 4 ...
