Survivorship characteristics and adaptive mechanisms of phytoplankton assemblages in ballast water

Journal of Oceanology and Limnology 2019年第2期37卷 580-588页

Phytoplankton diversity and abundance were determined in ballast water from 26 vessels in the Shanghai Yangshan Deep-Water Port from April 2015 to January 2016. In total, 84 species of phytoplankton were identified, belonging to 43 genera and 5 phyla. bacillariophyta (75.0%, including 30 genera and 63 species) were the dominant algae in the ballast water. Their density ranged from (5.55±9.62) SD to (1.878±0.872)×10 3 cells/L, with a mean of 410.1 cells/L. Nine potentially harmful phytoplankton taxa were detected: Ceratium furca , Ce . marcroceros , Leptocylindrus danicus , Coscinodiscus radiatus , Co . granii , Prorocentrum micans , Melosira sulcata , Meuniera membranacea and Skeletonema costatum . Our survey and identification results showed that Microcystis aeruginosa , Ankistrodesmus falcatus and Scenedesmus survived in the high-salinity ballast water, even though they are freshwater species. We identified the common features of surviving phytoplankton and impacts on the phytoplankton assemblage of ballast water age and source. Our goal was to understand the adaptative mechanisms of phytoplankton in ballast water, providing statistical and theoretical support for future ballast water research and suggesting a scientific basis of ballast water management and inspection of vessels entering the port.

用3 2 P分别标记 3 0 8bpcry1A上游和 65 0bpcry1C上游片段 ,并将标记后的DNA与不同苏云金芽孢杆菌菌株的细胞粗蛋白进行凝胶阻滞反应。结果表明 ,cry1A和cry1C上游均能被苏云金芽孢杆菌库斯塔克亚种 (bacillusthuringinensis subsp .kurstaki)的细胞粗蛋白特异性结合 ,而同一cry1基因上游序列可被不同多肽特异或非特异性竞争结合 ,不同的cry1基因上游序列也能同时被一种蛋白结合。说明苏云金芽孢杆菌某些特异细胞蛋白参与了cry1基因上游序列的转录调控作用 ,而不同的调节因子可能会竞争同一结合位点。库斯塔克亚种和鲇泽亚种 (b .thuringinensis subsp .aizawai)所含特异细胞蛋白在种类和作用上都有差异。

bACKGROUND Aprotinin has recently been associated with adverse outcomes in patients undergoing cardiac *** reviewed our experience with this agent in patients undergoing cardiac surgery at Duke University Medical Center. METHODS We retrieved data on 10,275 consecutive patients undergoing surgical coronary revascularization at Duke between January 1,1996,and December 31,*** fit data to a logistic-regression model predicting each patient’s likelihood of receiving aprotinin on the basis of preoperative characteristics and to models predicting long-term survival(up to 10 years) and decline in renal function,as measured by increases in serum creatinine levels. RESULTS A total of 1343 patients(13.2%) received aprotinin,6776 patients(66.8%) received aminocaproic acid,and 2029 patients(20.0%) received no antifibrinolytic therapy. All patients underwent coronary-artery bypass grafting,and 1181 patients(11.5%) underwent combined coronary-artery bypass grafting and valve *** the risk-adjusted model,survival was worse among patients treated with aprotinin,with a main-effects hazard ratio for death of 1.32(95%confidence interval[CI],1.12 to 1.55) for the comparison with patients receiving no antifibrinolytic therapy(P=0.003) and 1.27(95%CI,1.10 to 1.46) for the comparison with patients receiving aminocaproic acid(P=0.004).As compared with the use of aminocaproic acid or no antifibrinolytic agent,aprotinin use was also associated with a larger risk-adjusted increase in the serum creatinine level(Pbut not with a greater risk-adjusted incidence of dialysis(P=0.56). CONCLUSIONS Patients who received aprotinin had a higher mortality rate and larger increases in serum creatinine levels than those who received aminocaproic acid or no antifibrinolytic agent.
