Abstract: Microbial degradation of dissolved organic matter (DOM) in planktonic ecosystems is carried out by diverse prokaryotic communities, whose growth rates and patterns of DOM utilization modulate carbon and nutrient biogeochemical cycles at local and global scales. Nine dilution experiments (September 2007 to June 2008) were conducted with surface water from the highly productive coastal upwelling system of the Ría de Vigo (NW Iberian Peninsula) to estimate bacterial growth rates of six relevant marine bacterial g… Show more

“…4), suggesting that our incubation times were not too short to observe changes in the BCC. Teira et al (2009) conducted 11 dilution experiments over 1 yr in the Ría de Vigo (NW Iberian Peninsula) upwelling system and did not observe such large, systematic changes in the BCC as did Fuchs et al (2000). Their results were thus similar to ours, suggesting that the BCC was relatively stable in both untreated and amended incubations over short intervals (a few generation times).…”

“…Finally, %RP patterns were compared against available literature values for taxon-specific in situ growth rates (Yokakawa et al, 2004;Malmstrom et al, 2005;Allers et al, 2007;Teira et al, 2009;Ferrerra et al, 2011), and results showed that rankings of taxa based on %RP tracked well with rankings based on measures of in situ growth rates ( Figure 1d). Among the 200 top-recruiting reference bins, the percent of sequences identified as ribosomal proteins (%RP hits) within a genome ranged from 0.05% (Candidatus Pelagibacter ubique HTCC1002) to 20.5% (Chryseobacterium gleum ATCC 35910), and showed distinct phylogenetic patterns ( Figure 1c).…”

“…Interestingly, two SAR11 oligotypes (types_68 and 73) showed strong positive correlations with NOx (nitrite plus nitrate) concentrations. Although SAR11 are globally abundant in marine seawater environments (Morris et al, 2002), both negative (Eiler et al, 2009) and positive (Teira et al, 2009) correlations of marine SAR11 to ammonium and nitrate concentration have been reported. Thus, SAR11 members may be specialized for ecological niches defined by the availability of nutrients.…”
