, 2008 利用3种发根衣杆菌（LBA9402、R601、和R1000）转化纤维植物罗布麻无菌种子苗的根茎叶不同外植体部位，首次诱导其生成发根并实现了直接由发根途径的植株再生。罗布麻发根诱导与所用的发根农杆菌菌株，外植体部位及光周期密切相关。发根农杆菌LBA9402感染罗布麻的根外植体，实现了最高转化率达100％。与LBA9402及R601相比，被发根衣杆菌R1000感染的根外植体适合在黑暗环境下培养，其诱导生成的发根密度可达平均每个外植体22条。在不加激素的1／2MS培养基上 ...

, 2009 微囊藻毒素是一类由蓝藻产生的具有肝毒性的环状肽类化合物,是富营养化淡水水体中最常见的一种藻类毒素,也是蓝藻水华污染过程中产量最大、危害最严重的藻毒素种类.本文研究了微囊藻毒素MC-RR对大肠杆菌(Escherichia coli)和枯草杆菌(Bacillus subtilis)细胞膜的渗透效应,采用MC-RR和溶菌酶协同处理下由于细胞溶解而引起吸光值A675的降低来表示.结果表明,A675值的降低随MC-RR处理浓度和时间的变化而变化,浓度越高,A675值降低越明显,由此表明,MC ...
