Project description:Analysis of bacterial fraction collected on GF/F filters post pre-filtration on 1um filter. 15L were filtered from Bering Strait (BSt) surface water and Chukchi Sea (station 2) bottom waters.
Project description:The purpose of this study is to elucidate the proteorhodopsin function based on the genome of strain IMCC1322 which was cultivated species of SAR116 from East Sea of Korea. Light-enhanced photoheterotrophy of strain IMCC1322 is interrogated by the transcriptomics of IMCC1322 once the appropriate phenotypic characteristics are revealed by cultivation and polyphasic studies. Transcriptome revealed that green light (max. wavelength =522nm) drives metabolism and cessation of bacterial aging of IMCC1322. Here we report the mRNA profiling of IMCC1322 which is the first effort to the biogeochemistry of light-utilizing SAR116 group in the ocean.
Project description:Vibrio species represent one of the most diverse genera of marine bacteria known for their ubiquitous presence in natural aquatic systems. Several members of this genus including Vibrio harveyi are receiving increasing attention lately because they are becoming a source of health problems, especially for some marine organisms widely used in sea food industry. To learn about adaptation changes triggered by V. harveyi during its long-term persistence at elevated temperatures, we studied adaptation of this marine bacterium in sea water microcosms at 30 oC that closely mimicks the upper limits of sea surface temperatures recorded around the globe.
