Infrared Fast Repetition Rate Fluorometry (IR-FRRF) for Detection and Characterization of Photosynthetic Bacteria in Deep Sea Vents

Falkowski 9911948在这项研究中，Falkowski和Kolber将利用探索性研究小奖开发一种红外快速重复频率荧光仪(IR-FRRF)，作为一种检测海洋中光合细菌的新技术。目前与深海喷口有关的地热和/或地球化学产生的光的证据可能表明，海底可能存在非太阳驱动的光合作用。这项研究将能够量化光驱动的新陈代谢对这些细菌的总生物能量预算的贡献。这台仪器将为探索光合作用活性细菌生活在深海喷口相关光区或附近的假说提供新的能力。与辛迪·范·多佛博士合作，该仪器将于1999年11月和12月出海，对阿尔文从太平洋海隆喷口提取的样本进行检查。

Falkowski 9911948In this study, Falkowski and Kolber will use an Small Grant for Exploratory Research award to develop an Infrared Fast Repetition Rate fluorometer (IR-FRRF) as a novel technology for the detection of photosynthetic bacteria in the sea. Current evidence of geothermal and/or geochemically produced light associated with deep sea vents may indicate that non-solar driven photosynthesis could exist on the sea floor. This research would enable the quantification of the contribution of light-driven metabolism to the overall bioenergetic budget in these bacteria in situ. This instrument will provide new capabilities in exploring the hypothesis that photosynthetically active bacteria live in or near deep sea vent associated light regions. In collaboration with Dr. Cindy Van Dover, the instrument will be taken to sea in November and December 1999 for examination of samples retrieved by Alvin from vents on the Pacific Rise.
