Value <=194000 cells/ml
Organism Anaerobic Anoxygenic Phototrophic AAP bacteria
Reference Lami R, Cottrell MT, Ras J, Ulloa O, Obernosterer I, Claustre H, Kirchman DL, Lebaron P. High abundances of aerobic anoxygenic photosynthetic bacteria in the South Pacific Ocean. Appl Environ Microbiol. 2007 Jul73(13):4198-205.PubMed ID17496136
Method For the enumeration of AAP bacteria, seawater samples were fixed with 2% paraformaldehyde (final concentration). Samples were stored in the dark for 18 h at 4°C and then filtered onto 0.2-µm-pore-size black polycarbonate filters. Filters were stored at –80°C before microscopic counts. AAP bacterial abundances were determined following the protocol previously described by Cottrell et al. (8).
Comments AAP bacteria were a large fraction of the overall South Pacific prokaryotic community (up to 24%)
