Beschreibung:
The vertical distribution of bacteriochlorophyll a, the numbers of infrared fluorescent cells, and the variable fluorescence signal at 880 nanometers wavelength, all indicate that photosynthetically competent anoxygenic phototrophic bacteria are abundant in the upper open ocean and comprise at least 11% of the total microbial community. These organisms are facultative photoheterotrophs, metabolizing organic carbon when available, but are capable of photosynthetic light utilization when organic carbon is scarce. They are globally distributed in the euphotic zone and represent a hitherto unrecognized component of the marine microbial community that appears to be critical to the cycling of both organic and inorganic carbon in the ocean.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kolber, Z S -- Plumley, F G -- Lang, A S -- Beatty, J T -- Blankenship, R E -- VanDover, C L -- Vetriani, C -- Koblizek, M -- Rathgeber, C -- Falkowski, P G -- New York, N.Y. -- Science. 2001 Jun 29;292(5526):2492-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Environmental Biophysics and Molecular Ecology Program, Institute of Marine and Coastal Sciences, Rutgers University, 71 Dudley Road, New Brunswick, NJ 08901-8521, USA. zkolber@imcs.rutgers.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11431568" target="_blank"〉PubMed〈/a〉
