Degradation of three herbicides, atrazine, cyanazine and dicamba, was assessed in laboratory microcosms incubated under simulated methanogenic conditions using sediment from Pearl River of Southern China as an inoculum. Atrazine was much more resistant to degradation than cyanazine and dicamba over 300 days of incubation. Biodegradation of cyanazine and dicamba was further substantiated by establishment of enrichment transfer cultures in which the degradation of the respective herbicide was accelerated by the active microorganisms. Degradation of cyanazine initially involved the removal of chlorine and the two side chains, while that of dicamba was O-demethylation reaction forming 3, 6-dichlorosalicyclic acid. Results suggest that biodegradation of xenobiotics can be established through enrichment culture transfer technique, and further mechanism of degradation and microorganisms involved can be elucidated.

The perennial chenopod sub-shrub Artemisia halodendron Turcz. ex Bess. is endemic to the semi-xed and mobile sand dunes in Inner Mongolia of northern China and is an important sand-stabilizing plant. A. halodendron can persist through either sexual reproduction (seed- ling recruitment) or vegetative propagation. However, it is not known if there are differences in patterns of reproductive allocation in A. halodendron inhabiting semi-xed and mobile habitats. To characterize this, a test of eld measurements was conducted on two typical semi-xed and mobile sand dune habitats. In each habitat, 120 individual A. halodendron plants were randomly sampled at the time of seed production to examine changes in some reproductive characters including the number of owering shoots, dry weight of owering shoots, dry weight per owering shoot, dry weight of seed, and reproductive effort (RE = seed dry weight/total above-ground dry weight) between habitats. Although total above-ground dry weight and dry weight of vegetative biomass were similar between habitats, plants inhabiting the less eroded semi-xed habitat produced more owering shoots, greater dry weight of owering shoots, dry weight of seed and RE than those inhabiting the more eroded mobile habitat. This suggests that sexual reproduction is relatively favored by plants from the semi-xed habitat, whereas vegetative propagation is favored by plants from the mobile habitat. The allocation of resources to reproduction was size-dependent and specic to habitats sampled. Reproductive biomass and the number of owering shoots per plant increased with increasing vegetative biomass, with plants in the semi-xed habitat producing more owering shoots and greater reproductive biomass than plants in the mobile habitat. Plant size did not inuence RE, indicating that allocation of resources to reproduction appeared to be a constant proportion across all plant sizes sampled.

【期刊论文】Peptidemodelsoffourpossibleinsulinfoldingintermediateswithtwodisulfides
段舜山, XIAO-YUA NJIA, ZHAN-YUN GUO, YAOWANG, YEXUSHUN-SHANDUAN, YOU-MINFENG

The single-chain insulin (PIP) can spontaneously fold into native structure through preferred kinetic inter-mediates. During refolding, pairing of the first disulfide A20–B19 is highly specific, whereas pairing of the second disulfide is likely random because two two-disulfide intermediates have been trapped. To get more details of pairing property of the second disulfide, four model peptides of possible folding intermediates with two disulfides were prepared by protein engineering, and their properties were analyzed. The four model peptides were named [A20–B19, A7–B7]PIP, [A20–B19, A6–B7]PIP, [A20–B19, A6–A11]PIP, and [A20– B19, A7–A11]PIP according to their remaining disulfides. The four model peptides all adopt partially folded structure with moderate conformational differences. In redox buffer, the disulfides of the model peptides are more easily reduced than those of the wild-type PIP. During in vitro refolding, the reduced model peptides share similar relative folding rates but different folding yields: The refolding efficiency of the reduced [A20–B19, A7–A11]PIP is about threefold lower than that of the other three peptides. The present results indicate that the folding intermediates corresponding to the present model peptides all adopt partially folded conformation, and can be formed during PIP refolding, but the chance of forming the intermediate with disulfide [A20–B19, A7–A11] is much lower than that of forming the other three intermediates.

The zooplankton of 18 reservoirs of South China was investigated in 2000. 61 Rotifera species, 23 Cladoceras and 14 Copepodas were identified. The most frequent Rotifera genera were Keratella, Brachionus, Trichocerca, Diurella, Ascomorpha, Polyarthra, Ploesoma, Asplanchna, Pompholyx and Conochilus. Bosmina longirostris, Bosminopsis deitersi, Diaphanosoma birgei, D. brachyurum and Moina micrura were typical of Cladocera in the reservoirs. Phyllodiaptomus tunguidus, Neodiaptomus schmackeri and Mesocyclops leuckarti were the most frequent Copepoda and M. leuckarti dominated Copepoda in most reservoirs. High zooplankton species richness with low abundance was characteristic of the throughflowing reservoir, whereas low species richness with low abundance was found in the reservoir with the longest retention time. Relative high abundance and medium species diversity were the distinction of intermediate retention time reservoirs.

以绿色巴夫藻(Pavlova viridis)为实验材料,设置了18、36、54、65、86和108J.m-2 6个UV-B辐射剂量处理组,以无紫外辐射为对照,解除胁迫后,处理组和对照组在相同接种密度和相同条件下培养12d,测定了生长过程中的吸光值、生物量、叶绿素a、类胡萝素、可溶性蛋白质和胞内多糖含量,结果表明,在UV-B胁迫下,绿色巴夫藻细胞生长受到显著抑制,6个处理组细胞的相对增长率比对照下降了16.15%-60.00%(P<0.05).但在胁迫解除后,各胁迫处理的藻细胞生长指标均显著高于对照(P<0.05),证明绿色巴夫藻在胁迫后的恢复生长中出现超补偿生长现象,恢复培养第12天,最大吸光值、生物量、叶绿素a、类胡萝素、可溶性蛋白质和胞内多糖含量分别比对照提高了22. 38%、15.00%、26.15%、23.81%、11.63%和27.58%.藻类中存在超补偿生长特性为微藻生物活性物质的开发提供了有效途径,

以绿色巴夫藻(Pavlova viridis)为试验材料,设置了4、6、8、10Wcm2和12μWcm2个UV-B辐射强度,以无紫外辐射为对照,UV-B分别胁迫处理10min(a组)和15min(b组)。解除胁迫后,处理组和对照组在相同接种密度和相同条件下培养12d,测定了生长过程中的吸光值、色素含量、可溶性蛋白质和胞内多糖含量。结果表明,P. viridis 在UV-B胁迫下,藻细胞生长受到显著抑制,a组和b组辐射处理的细胞相对增长率分别比对照下降了17.70%~51.54%和26.16 %~60.01%(p0.05)。但是,当胁迫解除后,各处理的藻细胞生长速率,在恢复阶段前期(1~4d)与对照无显著差异,在恢复阶段的中后期(6~12d)则显(p<0.05)或极显著(p<0.01)高于对照。证明P1viridis在胁迫后的恢复生长中表现超补偿生长现象,恢复培养第12d 的最大光密度值比对照提高了26.55%,最大叶绿素a、类胡萝卜素、可溶性蛋白质和胞内多糖含量分别比对照提高了29.17%、29.93%、15134%和34.37%。当然,在各处理中,随着辐射时间的延长和辐射强度的增大,超补偿生长发生的时间也相对滞后。

综述了赤潮的发生与沿岸海域富营养化的关系。近几十年来,人类活动使得天然水体的富营养化进程大大加速。营养负荷的增加与高生物量水华的增多相联系。控制营养输入后,浮游植物生物量或有害藻类水华事件也相应减少。营养的组成与浮游植物的种类组成及水华的形成有密切联系。有机营养对有害藻类水华的促进作用受到关注。营养输入时机影响浮游植物种间竞争的结果,因而对浮游植物的群落演替具有深远影响。由于浮游植物存在生理差异,因而对营养加富的反应因种而异。营养在调控某些有毒藻类的毒素产量方面也发挥着重要作用。此外,营养输入与藻类水华之间存在复杂的间接联系。当然,营养状况并非浮游植物群落演替的唯一决定因素。研究结果提示,控制营养输入、减缓水域富营养化是减少有害藻类水华发生的有效途径,而深入研究典型有害藻类的营养生理对策则为防治并最终消除有害藻类水华提供了理论基础

采用LRH -GII型光照培养箱培养试验藻种,设置了持续黑暗胁迫(分6个强度处理)和间断黑暗胁迫(分4个模式处理)两项试验,研究了眼点拟微绿球藻(Nannochloropsis oculata)在不同环境胁迫下的生理生态变化和该藻种在黑暗胁迫下的超补偿生长响应情况.两个试验的结果均显示,眼点拟微绿球藻在持续黑暗胁迫和间断胁迫后,均表现出明显的超补偿作用现象.黑暗对眼点拟微绿球藻的生长造成显著抑制,但是适当进行黑暗胁迫以后恢复生长,微藻具有更强的生长繁殖能力,细胞净增率最大可达123%.经SSR测验,不同的胁迫方式、胁迫持续时间和胁迫模式与超补偿现象发生时间及强度密切相关,
