An optimized method for automated analysis of algal pigments by HPLC

A recent development in algal pigment analysis by high-performance liquid chromatography (HPLC) is the application of automation. An optimization of a complete sampling and analysis protocol applied specifically in automation has not yet been performed. In this paper we show that automation can only be successful if the various methodological aspects of the sampling and analysis protocol are considered in coherence. We introduce an optimized protocol that involves freeze-drying of the sample, subsequent extraction in 90% acetone and the application of water-packing during analysis. The method was evaluated on both natural plankton populations and a broad spectrum of microalgal cultures: Thalassiosira weisflogii (Bacillariophyceae), Emiliania huxleyi (Prymnesiophyceae), Phaeocystis globosa and Phaeocystis antarctica (Prymnesiophyceae) and Pyramimonas sp. (Prasinophyceae). Whereas pigment extracts were unstable in methanol, with recorded chlorophyll a losses from 10% to 60% per day, pigment degradation rates in acetone were generally less than 1% over 18 h storage in the autosampler (4 °C). In addition, it was found that the extraction efficiency of acetone significantly increased upon freeze-drying prior to extraction. Increases as high as 50–60% were measured in P. antarctica. The application of water-packing of the sample during injection resulted in improved peak shape and peak separation, without diluting the pigment concentrations. Automation is especially beneficial for application in the field, when mixed algal assemblages and low biomass put a high demand on the sensitivity as well as reproducibility of the method.

海洋微藻Chlorella sp．1061的脂类特征与分类探讨

采用生化分析方法研究了海洋微藻Chlorella sp．1061色素、极性脂及其脂肪酸组成特点。结果表明，Chlorella sp．1061色素、极性脂及其脂肪酸组成均与小球藻属的其它藻类存在着很大差异。绿藻纲中的主要化合物，如叶绿素b、十六碳四烯酸[16：4(n-3)]和亚麻酸[18：3(n-3)]均未在Chlorella sp．1061中检测到。从Chlorella sp．1061中分离到占总极性甘油脂8mol％的甜菜碱-1，2-二酰基甘油一O-4’-(N，N，N-三甲基)高丝氨酸(DGTS)，并从半乳糖脂和DGTS等极性甘油脂中检测到大量的二十碳五烯酸[20：5(n-3)](EPA)。但是一般认为，小球藻属藻类中不含这两种化合物。根据Chlorella sp．1061的这些特点，作者认为它不应该被归到小球藻属中。由于Chlorella sp．1061在色素、极性甘油脂及其脂肪酸组成特征方面与大眼藻纲(Eustigmatophyceae)中的拟微绿球藻(Nannochloropsis)非常相似，因此，Chlorella sp．1061可能是Nannochloropsis中的一个种。     

三种赤潮藻多克隆抗体制备及特异性分析

Polyclonal antibodies against three red tide algae with different size, Heterosigma akashiwo, Gymnodinium sp and Alexandrium catenella were raised in this study. Block affinity treatment was done to enhance the specificity of the antibodies. The titer of three polyclonal antibodies was determined by indirect enzyme-linked immunosorbent assay, and the specificity against polyclonal antibody was determined by indirect competitive enzyme-linked immunosorbent assy(icELISA). The result showed that Heterosigma akashiwo and Gymnodinium sp antibodies without block treatment got titer higher than 1:32000 and 1:10000, respectively, an indicating of high affinity antibodies. The titer of Alexandrium catenella antibody reached 1:2500, relatively lower than the previous two. The specificity of three polyclonal antibodies after affinity treatment was raised remarkably. However, the titer declined. All the polyclonal antibodies showed a high affinity with their own cells. Polyclonal antibodies were not remarkable cross reacted with other algae in the icELISA, The antibody of Alexandrium catenella reacted to its own cells, no cross activity was found with Alexandrium tamarense, which will be applicable in distinguishing species within the genus. The immunology technique was specific, sensitive and simple with low expend. This was provide a valuable tool for further experiment and had signafication to qualitative and quantitative monitoring of red tide algae.

Neocalanus flemingeri, a new species of Calanidae (Copepoda: Calanoida) from the subarctic Pacific Ocean, with a comparative redescription of Neocalanus plumchrus (Marukawa) 1921

Copepodites of Neocalanus plumchrus dominate the macrozooplankton biomass of the subarctic Pacific during spring. Living specimens have patches of bright red-orange pigment. During May of 1984 it was found sharing dominance with another, related species with differently placed patches of more distinctly red pigment. This is an undescribed species, which is designated here as Neocalanus flemingeri sp. nov. In the Gulf of Alaska it is smaller than N. plumchrus, but in the Bering Sea where food supplies are greater it reaches dimensions as large or larger. The morphologies of the two species are distinct, and previous confusion in the taxonomy of these forms was caused by differences in their life histories.

Alteration of benthic communities associated with copper contamination linked to boat moorings

Although copper (Cu) is an essential element for life, leaching from boat paint can cause excess environmental loading in enclosed marinas. The effects of copper contamination on benthic macrofaunal communities were examined in three San Diego Bay marinas (America's Cup, Harbor Island West and East) in Southern California, USA. The distribution of Cu concentration in sediments exhibited a clear spatial gradient, with hotspots created by the presence of boats, which in two marinas exceeded the effect range medium (ERM). Elevated sediment Cu was associated with differences in benthic assemblages, reduced species richness and enhanced dominance in America's Cup and Harbor Island West, whereas Harbor Island East did not appear to be affected. At sites without boats there were greater abundances of some amphipods such as the species Desdimelita sp., Harpinia sp., Aoroides sp., Corophium sp., Podocerus sp., bivalves such as Lyonsia californica, Musculista senhousia, Macoma sp., and polychaetes such as Diplocirrus sp. In contrast, at sites with boats, densities of Pseudopolydora paucibranchiata, Polydora nuchalis, Euchone limnicola, Exogone lourei, Tubificoides spp. were enhanced. The limited impact on Harbor Island East suggests not only lower Cu input rates and increased water flushing and mixing, but also the presence of adequate defense mechanisms that regulate availability and mitigate toxic impacts. At all three marinas, Cu in tissues of several macrobenthic species exhibited Cu bioaccumulation above levels found in the surrounding environment. The annelids Lumbrineris sp. and Tubificoides spp., and the amphipod Desdimelita sp. contained high levels of Cu, suggesting they function as Cu bioaccumulators. The spionid polychaetes Polydora nuchalis and Pseudopolydora paucibranchiata had much lower Cu concentrations than surrounding sediments, suggesting they function as Cu bioregulators. The macrobenthic invertebrates in San Diego Bay marinas that tolerate Cu pollution (e.g. P. nuchalis, P. paucibranchiata, Euchone limnicola, Typosyllis sp., Tubificoides sp.) may function as indicators of high‐Cu conditions, whereas the presence of Cu‐sensitive species (e.g. Podocerus sp., Aoroides sp., Harpinia sp., Macoma sp., Lyonsia californica) may indicate healthier conditions (less Cu‐stressed). Parallel responses by faunas of Shelter Island Yacht Basin, also in San Diego Bay, suggest potential for development of regional Cu contamination assessment criteria, and call for functional comparisons with other marinas and coastal water bodies.
