216 Prof. Edward Laws Louisiana State University, USA 美国路易斯安那州立大学 Intro: In this distinguished lecture, Prof. Laws firstly overviewed the background of CO2 effect on diatoms. Then he discussed his systematic study of the marine cyanobacterium Synechococcus strain CCMP 1629 under different conditions, with the goal to test the relative growth rate hypothesis of Joel Goldman, the algal growth model published by Richard Geider et al. He discovered a new observation that bacterial grow faster with high light, under nutrient deplete condition, independent on CO2, which is new from the reported model. This distinguished lecture clarifies the importance and courage to explore the established scientific models and inspires all the participants in their future research activities. 内 容 摘 要 : 在 此 次 杰 出 学 者 讲 座 中,L aw s教授首先概述了二氧化碳对 硅藻生长的影响。为了检验由 R i c h a r d G e i d e r 提出的藻类生长模型, L a w s 教授系统研究了不同条件对海洋蓝藻 Synechococcus CCMP 1629 菌株生长的 影响。通过一系列的研究,他发现了一 个与之前报道的模型完全不同的结果, 即在营养不足的条件下,海洋蓝藻在强 光下生长更快,与二氧化碳的多少无 关。这个新发现对以后海洋藻的培养及 研究至关重要 。 Interactive effects of temperature, irradiance, nutrient limitation, and CO2 partial pressure on the growth and physiology of the marine cyanobacterium Synechococcus 温度、幅照度、營養局限和CO2分壓海洋藍藻集聚球菌 Sy n e c h o c o c c u s的生长和生理的相互作用影响 Distinguished Seminar Series 2 香港分部第二次杰出学者讲座 Date 日期 : 10 June 2021 (Thursday) 2021年6月10日 (星期四) Zoom Meeting 线上平台 ID : 207 460 5139 Participants 参会者 : 92
